Make Sure You Have A Good Flange
Standard flanges of large diameter is not necessarily mate. Andrew Sloley offers a look at Plant Insites column this month.
The system was adding a three-stage vacuum ejector for steam. We would like to discuss with us from time to time by representatives of local suppliers to ensure that the instruction schedule. Everything was expected, as stated in all devices of the system in the near future to supply export and transit to the factory to complete.
Shortly before the ship date, EPR has asked me to ask me for lunch and it was unusual for him. Apparently he wanted something, but I do not know what. My boss told me, less cynical and simply enjoy a good meal. The breakfast was wonderful and went well.
Then, the EPR has gradually come to see me with a statement about a small problem with the equipment of the vacuum system. The purpose of this meal was finally free in nature.
The steam system were three stages of capacitors after each step. Capacitor reduce the load for the next phase of the condensation of the steam engine, steam from the process and the process may be condensed. The first stage is designed with ejector directly related to the first capacitor. Three parallel lines are combined into a single seal drum (also called).
We wanted at least one complete set of soaring in the shop of the seller prior to shipment. This required manufacturers to take delivery of heat and do the installation. The soaring preferred suppliers for each component suppliers to deliver directly to our site. However, she said: Just humor us for at least one laboratory in the file. In the end, we have concluded an agreement to take a train track.
The problem occurred at the meeting. The 30-in. Flange output capacitor of the first phase of mate with 30-in. Intake flange of the condenser. Have been ordered Rush to take the respective flanges and repairs.
The incident took place well before the American Society of Mechanical Engineers (ASME) was launched in 1980, official efforts to develop a single flange for pipe diameters 26 inches and above. Until then, two different models of the flange were common: the standardization of civil manufacturers (MSS) sector of the valve, and the American Petroleum Institute (API).
The MSS-44-Standard for Steel Pipe Line Flanges radically different from the API-605 standard for large diameter steel flanges carbon.
Figure 1 contrasts with the size and layout key for the category 150 of sealing films. Obviously inappropriate. The manufacturer of ejection had used a type of flange and heat had another supplier may be used.
ASME was looking for a single design of the nominal diameter of the tube, 26 inches. 48-in. Brides. Let MSS or API, or both, should be changed to create the model. Neither move would be. So far we have ASME / ANSI standard has two parts. ASME B16.47 Series A offers a the amount of MSS flanges and a series of B corresponding to the flanges API. For class 150 and class 300 (all sizes) and 36-inch and smaller classes, higher than Class 300 Series A and Series B flanges are not compatible.
Thus, while our problem is occurring before the ASME was a single standard does not eliminate the problem. Isolated mismatches continue to provide accurate information, lack of awareness of the Series A or B. Only a few engineers that two possible types of large-diameter flanges are available. If you have a large flange diameter, check what you need to make sure that what you get.

Process Puzzler: Soothe A Skittish Supervisor
THIS MONTHS PUZZLER
We use a carbon-steel spiral-tube heat exchanger as a condenser in our spray tower. Operating conditions normally are 100 psig at about 150°F. Treated chilled water at 45°F runs in the tube side. The shell side handles metal chlorides, e.g., FeCl2, VCl4 and TiCl4. These chlorides condense to form liquids and evaporate to form gases Stainless steel pipe. Severe corrosion from chlorine and erosion was the reason why the spiral heat exchanger was chosen over a shell- and-tube one. The chlorine is usually dry but, occasionally, spikes of water upstream of the exchangers cause corrosion. One of our engineers is pushing the idea of cladding Type 304L stainless steel with a high nickel alloy. Coupon tests suggest this will improve service life. One concern is how bending the tube will affect cladding. How can we assure our nervous operations manager that this cladding will work? Do you have any other ideas? Keep in mind replacing the heat exchangers with another style will require a major change in piping around the units.
REPLACE THE EXCHANGER
Try looking at a hybrid heat exchanger that incorporates the strengths of both plate-and-frame and shell-and-tube exchangers without their weaknesses. It is a good compromise between cost and performance. My experience is only as a happy customer of an exchanger manufactured in France. Its design tends to provide the best lifecycle cost choice for our circumstances.
LOOK AT TANTALUM LINING
I think that you have not considered all of the options available. Cladding is a risky option. Maybe replacing the tubing with duplex steel would be a better option. Another idea would be to seek a consultant. There is a manufacturer in Germany that makes tantalined equipment for the fabrication of spiral exchangers with lined carbon steel pipe. This last item might be your best choice.
WATCH THERMAL EXPANSION
We have used nickel-plated copper seamless pipe tubing for similar heat-transfer applications. The plating can be applied after the tubing is bent, but youll need to be careful about the amount of expansion you get from temperature variation.
CONDUCT THOROUGH TESTING
Some years ago an engineer at our plant in Grimsby, U.K., looked at tantalum cladding for our chlorinators. These are large brick-lined reactors. Inside, chlorine comes in contact with carbon monoxide from burning coke; the chlorine reacts with ore to chlorinate it, producing titanium tetrachloride, TiCl4. Trace water and hydrogen chloride (HCl) in recycled chlorine is a continual problem. Unfortunately, the brick and carbon steel shell of the chlorinators is quickly attacked at the moisture penetration zone where the water and HCl condense. These chlorinators are water-cooled by falling-film heat transfer, making it difficult to detect a breakthrough of the shell. Such a breakthrough posed a significant environmental risk.
The engineer thought tantalum, the only material not susceptible to attack by wet chlorides, would work. He was looking into coupons to test in the next chlorinator turnaround. These coupons included welds and other features.
With the heat exchangers, the combination of welds and bends offer a challenge for coupons. I suggest installing a coupon that includes welds and a distressed plate, not unlike the forming process for an elbow. Test in a large vessel, if possible, to avoid affecting the chlorination process. If the coupon survives, your cladding idea may succeed. The next test involves checking the manufacturing process. A very good test for identifying cracks in metal tubes is an acid dye-penetration test. Its a destructive test that will reveal voids in the interstitial areas between crystals in nickel alloys and similar metals that ultrasonic means wont identify. Use this method to validate the manufacturing process.
It would be really easy to grow shy about this application. When we considered cladding of our heating coils, which operated at about 1,000°C, we opted out. We felt that it was too risky and chose to go with high nickel alloy coils instead.
MARCHS PUZZLER
Management wants to boost production from our batch polymer process by changing the operating procedure. Now, a portion of the acrylic monomer goes in with the bulk of the solvent and other ingredients. Then, monomer is slowly added until the reactor level rises to about 55%. Instead, management wants to increase the maximum level to about 65% and raise the final concentration of the polymer about 2%. The reaction is very exothermic; a chilled-water baffled jacket provides cooling Stainless steel. At the top of the reactor a horizontal shell-and-tube condenser that uses cooling tower water captures evaporated solvent. Agitation consists of a single axial impeller and the tank has reduced baffles to account for viscosity above 5,000 cP. To meet the production goal, its been proposed that we add all of the monomer at once; bench-scale tests have shown that this could work but our current approach seems safer. Management likes the plan and wants to put into practice immediately. Our production engineer is a little nervous should he be concerned? How should we approach this problem? Are any process changes necessary? What do you think?
And, of course, if you have a process problem youd like to pose to our readers, send it along and well be pleased to consider it for publication.

R4 Ds Complete Guide
Set up the R4 so that it works on your ds.
Required Materials
R4DS package
A computer (Mac or Pc doesnt really matter)
A micro SD
DS or DS lite
Part 1: Setting up Your R4DS
Put the micro SD into the USB-micro SD adapter and plug it into your computer. Then you download the required stuff from the R4DS website (it use to be on a cd but now its on the website) You can make all the new file hidden so it you dont see it in your DS After that you can either download a starter pack which will have most of the stuff you need or you can just find everything yourself. If you dont download a starter pack the first thing you should do is to make 3 folder in the r4ds name them Games Multimedia and homebrew. In the Multimedia folder you should make 3 folders music videos and pictures. That is about it for set-up.
Part 2: Putting Stuff onto Your R4
You can look for themes and download them from the Internet. After you do that you just replace the theme that is already in the computer. For music you just put the mp3 into your folder and it will work. For videos you have to download a program called Super and change the video format to dpg. Then you just put it in the R4 Cards and it should work. Games I would use homebrews because its legal unless you already have the game and you just want a backup in case you break the game.
Part 3: Turning on the R4
Place it in the DS and turn it on. If the DS doesnt recognize the R4 there could be 2 problems. It could be you got a fake copy or most likely that the receptors on the R4 are not touching the receptor in the DS. To solve the problem you could just insert a piece of paper with your DS so that the receptors touch or you could take apart the R4 with a tiny screw and add a piece of paper between the chip and the plastic. When you open the R4 you will see a screen with 3 figures Games Multimedia and slot 2 (which is the GBA slot). When you click on Games it will allow you to play games. If you click on the multimedia circle then you can listen to music or watch video.
Recommended Stuff to Put on Your R4
Bible.nds Great program if youre a Christian
DSReader Read book and faqs for you games
IpodDS Looks cool and plays music
Comicbook R4 DS Great if you read comics
Svsip Great to prank call people or just to call people
These are what I mainly use however there are many more all you got to do is look around.

Types of Flanges and How to Flange Pedal Works
Flange are used to connect together pipes or to connect a pipe to a choke, tee, valve or other equipment. There are seven main types of flanges and they come in rectangular, square and round shapes to accommodate a variety of needs and projects.
Lap Joint Flange
For pipes that are frequently taken apart for repair or replacement, lap joint flanges are used. These flanges are used with a universal stub-end insert that is easily rotated and makes it easy to line up bolt holes. This type of flange is used for junctures that do not come in contact with anything flowing through the pipes, which increases their durability and renders them reusable. Caution should be taken not to use lap joint flanges for jobs where high temperatures or high pressure conditions are possible.
Slip-on Flange
Slip-on flanges are thinner than most flanges as they are slid over pipe ends, easily aligned with bolt holes, and then permanently welded into place. Unlike lap joint flanges, they are designed to withstand contact with liquids and can withstand low-pressure atmosphere. They are stronger than other flanges, low cost and dependable at preventing leaks.
Threaded Pipe Flange
This popular type of flange not only comes in a wide range of materials and sizes, it can also be attached to pipes without welding, as it is a threaded flange. Extremely useful in connecting small pipes, it is a low cost flange that can be safely used in highly explosive and high pressure areas of projects and machinery.
Weld Neck Flange
The most popular type of high pressure pipe flange is the weld neck flange. The tapered hub design provides an extremely strong connection and these flanges can be repeatedly manipulated and bent without compromising the quality of the material and/or connection. The weld neck flange is highly resistant to extreme high and low temperatures.
Socket Welding Flange
The socket welding flange was created specifically for small piping that must withstand high pressure and/or contact with chemicals. With expert grinding and welding, socket welding flanges allow the unfettered flow of any type of liquid.
Blind Flanges
These flanges are commonly used to seal or blank off the ends of valves and pipes. They are always round and have bolt holes around their perimeter. They are economical.
Reducing Flange
Some piping system designs require constant changes in pipe diameters to accommodate changing conditions. The reducing flange economically connects different types and sizes of flanges, can endure extreme changes in pressure and are easy to attach.
Creating the Effect
To produce the flanging effect, a flanger pedal mixes two identical signals together from your instrument. One of these signals is then delayed in varying amounts. The delayed track is slowed down very slightly (as if one was gently pushing down on a tape reel as playing and then sped up in order to catch up with the other track. This creates a spinning, sweeping effect like the sound of a jet plane passing overhead.
Delay Amounts
Although flanger pedals delay the copied signal, there is no echo heard. This is because the delay times amount only to the range of one to 10 milliseconds. The human ear can only distinguish an echo if the delay is over about 50 milliseconds. Instead, as the low amounts of delay are used and varied within this tiny range, the listener will only detect the pitch modulation from the delayed track as its signal is read slower (creating a slightly lower pitch) and then faster (for a higher pitch).
Controlling the Sound
Most flange pedals allow you to shape your sound by rotating dials that control the amount of delay added to the delayed signal. This is usually labeled as the "depth" control although on some pedals it will read "mix." The depth level determines how pronounced the notches in the flanger effect will sound. Some pedals also have a sweep depth (sometimes called width) dial to control how noticeable the pitch modulation in your flanger effect will be.

Brush And Satin Finish On Stainless Steel
While at first glance deburring & finishing stainless steel and aluminum railings may seem somewhat a niche market it should be noted that with the correct Dynabrade tools, grinding, sanding and polishing products almost any weld shop can take on this type of work.
It is hard to put a number on how many steel fabricators, welding shops, artists garages, etc. I have been called into because a nervous owner, foreman or project manager took on railing jobs that were above their expertise. Most thought they were going to lose their shirt once they got to the metal finishing stages on somewhat temperamental stainless or aluminum.
The best advice I can give anyone who wants to Brush Finish Stainless Steel or Aluminum Railings in a professional manner is set up your shop and your polisher with the necessary Dynabrade tools and Abrasives. If you are willing to allocate some of your time and hard earned money as an investment in yourself and your company the quality stainless or aluminum railings you produce will come back to you financially many times over. The most common abrasives questions I get asked for these metal finishes are some of the easiest to answer. Thats not to say I havent seen some interesting challenges over the years. I have been in over 1,000 shops that work on all types of metals and woods.
A consistent finish on stainless or aluminum railings steel fabricators want to achieve is a brush, satin or #3 finish or #4 finish. Most steel fabricators order the stainless steel or aluminum pre-finished to this specification and only need to bring the areas they have welded back to a nice clean satin finish which will match the rest of the metal railings original finish.
I like to see anyone who is serious about working with metals such as stainless or aluminum own at least two Dynabrade tools for their shop. The first is a Dynabrade Dynafile. There are many variations of the Dynafile which Dynabrade Manufactures. They are as follows: The Original Dynafile model 14000, the dynafile II model 40320, and the Electric Dynafile model 40590. Either one of these Dynafiles will do the job.
I prefer the Dynafile II series air or electric. They seem to be the most versatile. You can position the rotating sanding belt head in many different positions depending on the angle of your work piece. The Electric dynafile II and the Air Dynafile II also accept over 20 interchangeable contact arms which will hold sanding belts and surface conditioning belts 1/8 to ? in width.
The Dynafiles primary function is to grind and polish hard to reach areas on a metal work piece. Some examples of this are the corners or where the welds join together two or more parts. The second Dynabrade Tool I find to be a necessity from Dynabrade is from the Dynastraight Family. These tools include: The Dynastraight model 13204 .7 hp 3,400 RPM or the Dynastraight model 13505 1 hp 3,400 RPM.
I like these models because they are rated at the proper RPM and have male 5/8-11 threaded wheel arbors which are standard and allow for many different abrasives to be mounted and used on them. If you want to use a dynabrade inflatable rubber drum with sanding belts or surface conditioning belts on it the Dynabrade Pneumatic Wheel seamless pipe part number is 94472. I also recommend a combination of unmounted 6x1x5/8 flap wheels in assorted grits for either Dynastraight to help bring the Railings back up to the 3 finish or 4 finish.

Disposer Flange And Sink Strainer
The disposer flange and sink strainer includes a strainer unit, a seat, and a mounting flange. The strainer unit comes with a handle, a strainer member, and a plug member while the plug member has a platform and a surrounding wall depending from the platform on which multiple slope guide is located.
The seat used in the disposer flange and sink strainer includes a limiter located at a lower portion of the seat. It also includes a snapping portion at a top of the seat. The seat also includes a stopping surface protruding from and surrounding a middle portion of the seat, and there is also another snapping portion at the bottom of the seat.
The mounting flange in the disposer flange and sink strainer is available at the top end with a flange portion and at a bottom end with a mounting portion. You can also find some units in which the sink strainer may further include a decorative flange having a flange portion and a snapping portion. These portions are dimensioned and configured to abut on, and be engaged with, the flange portion and top-snapping portion of the seat.
It is really a fact that Louis Vuitton always made creative items by the classical legendary Monogram pattern, no matter what they are Louis Vuitton handbags, or watches. Just like the Tambour Diving Lady Watch with dazzling red color.
Bright and elegant, this lady watch is absolutely your perfect accessory for Summer holiday, What's more, it is right for your wrist whether you're in a suit or party dress even the casual jeans. Now, let's check it carefully.
Replacing the sink strainer from the disposer flange and sink strainer is also very simple. The sink strainer is the fitting secured to the sink bowl. The first thing in order to replace the sink strainer is to remove the old one.
Thanks for the diamonds detail, the watch features a truly glamorous look. As for me, I mostly like the bright red rubber strap since it looks so lively and energetic. What about you? In a word, totally a luxurious sprorty design. Best functionality and fabulously designed for best style - I finally realize that why it could become the enduring fashion brand for so many years. What's your opinion?
However, you must keep in mind that you can also find units in which the strainer is held with a large lock nut. There are another type as well that has three screws. Once you have removed the sink strainer, all you have to do is to install the flange that comes with the disposer, applying plumber's putty under its lip to form a seal with the sink bowl.

The Worthy of Stainless Steel
Over the past century, stainless steel has arisen as the first metal of choice for many applications. You will find stainless steel at the top of skyscrapers, in your sink and in your hands as you use tools and various other objects. But is stainless steel really all that great? How does it compare to other metals? Here is some basic information about stainless steel to examine its worth and popularity compared to other metals.
What is stainless steel?
Stainless steel may be defined as an alloy of iron and carbon with a chromium content from 10.5 - 11.5%. Metallurgists began working to form stainless steel in the 19th century, but it was not until the early 20th century that stainless steel became mass-produced and widely used. The chromium content is the secret to the stain-resisting properties. When chromium comes into contact with oxygen it creates a film called chromium oxide that encases the steel and provides a sort of barrier against corrosion. Whenever the layer of chromium oxide is breached, it will "self-heal" and continue to create another film as the exposed chromium interacts with oxygen.
Can stainless steel rust?
Yes. It is important to note that while stainless steel does strongly resist any form of corrosion, it is not completely immune to corrosion and rust. While only gold and platinum are entirely impervious to corrosion, stainless steel is the most economical choice for endless applications. The best way to prevent stainless steel from rust and corrosion is to keep it clean. When kept clean, this steel can come into contact and withstand diverse environments and chemicals. Abrasive materials can break down the ability of stainless steel to resist corrosion. Whenever cleaning an item made of stainless steel, refrain from using abrasive materials or brushes. Soft cloths and various kinds of soap are recommended as long as they do not contain chloride.
Stainless Steel Grades
The most common grades are 304 (18% chromium, 8% nickel) and 316 (16% chromium, 10% nickel, and 2% molybdenum. Grade 304 is the most versatile and widely used stainless steel. Originally it was called 18-8 because of its chromium and nickel content. Grade 316 has superior corrosion resistance and is often referred to as the "marine grade stainless steel" and is used in food and laboratory equipment, medical devices, threaded fasteners, and marine applications. Grade 302 has given way to 304 due to availability and price but is still found in items such as washers and springs.
How has it been used?
Stainless steel is perhaps one of the most broadly applied metals in the world today. One will find seamless pipe in everything from buildings, to wrist watches, from monuments to skate blades. In 1930 the Chrysler Building in New York City was erected and capped with 302 grade stainless steel. A recent inspection of this building reveals the durability of stainless steel and its resistance to the elements as no corrosion or loss of thickness was found. The St. Louis Arch is the largest man-made monument in the United States. The concrete arch is covered with nine hundred tons of stainless steel from top to bottom. [3] Ever since 1965 when the arch was completed, cleaning is the only maintenance the 603 ft. monument has needed.
While the average person may not always have contact with these two monumental structures, most people interact with stainless steel products every day. Many household appliances from cabinets to sinks to dishwashers consist of stainless steel. This metal is chosen often in the kitchen because of its durability and sharp aesthetic appeal with only the occasional cleaning necessary to maintain its look.
Stainless steel is not merely good for aesthetics, but many tools are now made from stainless steel. Because of the superior strength and durability of the metal, homeowners and businesses have chosen to incorporate stainless steel tools. One business has even commented, "Replacing carbon steel tools with stainless steel tools eliminates this risk and should be considered a standard operating procedure for any modern facility." High-risk jobs require reliable tools that won't corrode or break during use. No one likes to find a tool rusted when it is needed for a particular job in the house, and homeowners can't afford to continually buy replacement tools.
Hardware made of stainless steel benefits the user with all the above qualities of stainless steel. Today you can find stainless steel hardware from basic nuts, bolts, screws and chain. You'll also find highly specialized and complex fittings and hardware used for rigging and marine applications.
What about other metals?
One of the most common elements in the entire universe is iron. Because of its abundance and relatively easy accessibility, iron has been a popular metal for tools and various other objects for several millennia. Cast iron is used to make bicycles, machines and hardware. Yet, iron metals may break and are easily susceptible to rust. Rusting takes place whenever iron materials come into contact with oxygen and water (moisture). Because of this liability, rusted iron loses integrity and can become dangerous in critical situations.
Nickel is a metal commonly used as an alloy. Even the nickel as currency is 75% copper. Nickel is commonly used as a metal in cast iron or even stainless steel. However, nickel is seldom used as a metal unto itself.
As was stated earlier, titanium stands out as one of the only elements in nature that is of itself completely rust resistant. Titanium is uniquely light, durable and dent resistant. Yet, with all of these qualities, titanium needs to be refined and is not normally produced in vast amounts. This results in high prices. Normally, titanium will be included in an alloy such as stainless steel or aluminum. Sometimes it will show up in watches or even wedding rings, but again, only in small amounts because of supply and cost.
Zinc is another metal, like nickel, that is better applied in alloys. Often times it is used to coat other metals for corrosion resistance. Architects increasingly employ this material for its UV resistance, natural tones and corrosion resistance.
One of the most common and cheapest metals is aluminum. When in its pure form, this metal is relatively weak and impressionable, but when united to other metals in alloys it becomes much stronger. If aluminum is used for critical applications, it appears as an alloy. Because this material is so light and cheap, most large objects (cars, planes) that require a large metal structure incorporate aluminum as an alloy.
These metals (and a few others) each have their own particular benefits. Rarely will any of these materials constitute a single object by themselves. Normally, objects are a composition or alloy of several of these metals. Even though stainless steel is always composed of iron, carbon and chromium, it may have these other metals as well. All things considered, it should be noted that stainless steel as such is a superior metal in a lot of ways. It is extremely strong, stain resistant, and can be fashioned to fit many different applications.
While titanium and gold may be stronger and more durable, their cost makes them an impractical material for objects when stainless steel pipe can accomplish the job with extreme efficiency and lower cost. The growing popularity of stainless steel over the past century has not happened by accident. If you are considering purchasing a tool, appliance or building a national monument, you should employ the superior qualities of stainless steel. Without a doubt, stainless steel is worth the extra cost as it returns years of durable service in whatever form it is used.

CNC Programmer Jobs in Plastic Mold Making
Without the CNC programmer, any modern plastic mold making operation grinds to a complete stop-quickly! Just consider for a moment just how many machines use the CNC programmer.
The CNC programmer might work on programming a 5-axis CNC milling machine, WEDM machine, CNC EDM sinker, laser cutting machine, CNC lathe, and more. He also might be responsible for the programming of electrodes for the EDM machine, among other things.
A CNC programmer needs to understand nearly every aspect of plastic mold making to be truly efficient. In fact, most CNC programmers have extensive practical experience in the shop. Many apprentices who show an inclination for programming end up as a CNC programmer.
Most injection mold making shops have CNC programmer jobs available at almost any given time. This is especially true for someone with Fadal CNC experience, CNC engraving experience, or is competent with CNC CAD CAM programming.
What about the pay?
Generally, most CNC programmer jobs pay similarly to that of a plastic mold maker. This is true unless the CNC programmer lacks the hands on practical experience from working in the shop. A technical school graduate will find it easier to get the job, but the pay may be less to begin with than that of an apprentice Plastic mould maker who becomes a CNC programmer.
How do you become a CNC programmer?
Basically, there are two routes to take. One is to become an injection mold making apprentice, with the understanding that your main interest is in CNC CAD CAM programming. Over time you will be steered more and more in the direction of CNC programming.
The other route is to take a course designed specifically to learn the skills required to get one of the CNC programmer jobs you are hoping to win. Some technical colleges offer courses; as well as community colleges and universities. This path can land you a job more quickly because you already are partially trained and can begin producing for the company quickly.
One path is not necessarily better than the other in the long run though.
What is a typical day like for a CNC programmer?
Obviously, a greater part of your day is in front of a computer monitor. There are also many times when you will need to be at one of the many machine tools you are programming. This variety can provide a welcome respite from sitting all day in front of a computer screen.
You also will be communicating with the various machine operators, Rapid prototype designers and the mold makers. The work of a CNC programmer touches almost every aspect of the entire mold making process. This can make you a hero, or a villain!

Tips For Installing Closet Rods
Closet tubing: what you can expect to find
Profiles and sizes
Closet tubing comes in a variety of shapes, sizes, materials, and colors. The most common shapes, or profiles, are round and oval. Round closet rod is sold in 1-1/16 inch diameter tube and 1-5/16 diameter tube. It can be purchased in steel, stainless steel, and aluminum.
Round closet rod generally carries more weight due to the shape of the tube and usually has a thicker wall. While either size is suitable for a closet, for maximum weight bearing capacity use 1-5/16 diameter rod.
Oval tube isn't truly oval in shape but more of an oblong rounded shape with two flat sides. It normally measures 15 x 30 mm or approximately 1-1/8 x 1-1/4 inches. Oval tube is manufactured in steel or aluminum.
Materials
Metal closet rod is available in Steel, Stainless Steel, and Aluminum. Steel is typically sold with a Polished Chrome finish; this is the most common closet rod material and finish. Its advantages are strength and durability at a lower price. Stainless Steel is typically sold with a satin or brushed finish. It offers the strength and durability of steel with the added advantage of rust and corrosion resistance. Stainless steel is ideal for humid and sea-side applications.
Aluminum is sold in a variety of anodized finishes. Anodizing is a process in which electricity is used to produce a hard and durable surface. Aluminum tubing is much lighter in weight but with a similar load bearing capacity to steel.
Evaluate your needs
Length - The first thing you should consider for your installation is the length of the closet rod. The length should be determined by measuring the wall to wall distance. Dry wall often has very slight waves or undulations in it so that the distance between walls may differ from one spot to another. For this reason it's important that you take your wall to wall measurement at the exact spot where the closet rod will be installed. Usually the closet rod is mounted at least 12 inches from the back wall. Having someone help you measure will make the job much easier and give you better results. If you need a closet rod over 8 feet long some profiles and finishes are available in extended lengths up to 12 feet.
Weight bearing needs - Next, decide what kind of clothing will be stored on your closet rod. While a mix of garments is expected in a normal closet, an Arizona wardrobe will be much different from a Minnesota wardrobe. Cold weather clothing will weigh a lot more and that should be taken into consideration. A closet rod in a coat closet will need to support a lot of heavy items while a closet rod in a nursery closet will not need to support much weight at all. Keep in mind that the longer the closet rod the more likely it is to sag when loaded with clothing. Center supports and shelf/rod brackets will keep the closet rod straight. As a general rule, closet rods under 5 feet don't require center support. For longer spans consider using center supports every 3 or 4 feet.
Finish - After the practical needs of your closet are determined you can concentrate on aesthetics. Profile shape, color, and finish should fit the décor of the closet and surrounding room. With so many choices available you should have no problem finding something to suit your taste.
Mounting Flanges
Mounting flange are the supports that attach to the wall and hold your closet rod up. Each type of rod will have mounting flanges made specifically for it but there are common types of flanges used for all tubing. Open flanges are made with the top portion open like a "U" so the closet rod can be easily lifted out. Closed flanges completely encircle the end of the mounted closet rod and do not allow removal without unscrewing the flange from the wall. 32mm pinned flanges are made to work with 32mm systems or European Closet systems. These are closet systems that have pre-drilled holes spaced at 32 millimeters running up and down the closet side panels. While 32mm flanges can also be screwed in place, this isn't necessary and foregoing screws allows adjustment of the closet rod up or down if you wish. 32mm flanges are available for round and oval tubing in open and closed variations.
Accounting for mounting flange space
Since the mounting flange may have a back-plate, the flange you use will determine the cut length of the rod. For instance, if the wall to wall measurement is 60 inches and you are using two open flanges you'll need to subtract ? inch from the total length of the rod. Each open flange has a 1/8 inch back plate. 1/8 + 1/8 = ? inch of space that will occupy the total length of 60 inches. Some closed flanges have an opening all the way through so that your closet rod will actually touch the wall. In this instance the rod itself could actually be 60 inches long. Be sure to find out what space your mounting flanges will take up and factor that into the total length of the application. Each flange has a cuff, the part that encloses and supports the end of the tube. The cuff will be between ? inch and 1 inch deep. Keeping in mind the cuff depth you may want to cut the closet rod just slightly shorter to give yourself some "wiggle room".
Cutting Closet Tubing
While it is possible to cut closet tubing yourself it's usually worth it to pay a cutting charge if that service is provided by your supplier. If you do decide to cut it yourself use a saw blade made for cutting metal. Be sure to use your saw as directed by the manufacturer to prevent accidents!
Installation
Once you have everything measured and cut you may proceed with installation. This step will be easier with some assistance so get a friend to help. You've already made sure that your tubing is adequate for your closet, now you need to make sure that it's firmly and securely mounted in place. The mounting flanges are far more likely to tear loose from the wall than your closet rod is to bend so it's critical that this step is done correctly! If the closet rod is to be attached to dry-wall be sure that it is located so the screws go through the dry-wall and into a wall stud. Dry-wall alone is not sufficient as a mounting surface. If you're unable to screw into a stud, plan on using a wood mounting board on top of the wall. This should be firmly attached to the wall studs and will provide a suitable point of attachment for your mounting flange. If you do use a mounting board remember to subtract its thickness from your wall to wall measurement when determining your closet rod length. Depending on the type of flange you're using, it may be screwed in place before the rod is set or it may need to be slid onto the rod prior to screwing in place.
Using Your Closet
Once everything is in place you can start filling your closet. While metal tubing has a very durable finish it can scratch if used roughly. It's always a good idea to use quality hangers to protect your clothes and your closet rod. Plastic hangers will ensure that the finished surface remains scratch free. Wood and metal hangers are fine just as long as the hook has a smooth finished end. Wire dry cleaning hangers have sharp ends and should be avoided.

Design and Uses of Perforated Stainless Steel
The perforating of stainless steel is a process made popular due to the many desirable and durable properties of this alloy. Stainless steel is essentially a steel alloy with a minimum of 10% chromium content by mass. Stainless steel (It stains less) is named just that; because it does not stain, corrode, or rust as easily as ordinary carbon or mild steel. It can also be called corrosion-resistant steel. One common misconception however is that it is stain proof, this is an exaggeration of its metallurgic properties.
Stainless steel is available in various grades, approximately one hundred fifty total, yet only fifteen of these grades are commonly used. The individual grades of stainless steel are divided into groups or series based on their specific composition (100, 200, 300, 400, 500, and 600 series). The stainless steel is also classified according to its aesthetic finish which is applied after the material has been milled to size and thickness. Some examples of popular finishes are matte, satin, brushed, reflective, mirror, and a simple coarse abrasive finish.
Perforated stainless steel is typically produced using two popular production methods. The first, and more popular, is an all-across perforating press which perforates a row or pattern of holes across the material. The material is fed through the press in a precisely controlled fashion to produce a repetitive pattern. The finished material is automatically sheared or cut into specific lengths to create individual sheets.
The perforated stainless material can also be left intact as a single length of material and wrapped into a coil. A sectional or two axis perforating press is another method of producing a perforated seamless pipe sheet. In this case, the machinery moves the raw material beneath a stationary punching head in various patterns using two horizontal axes to guide the sheet. The end result is a pattern of holes based on the machine program and the desired output. This method is popular for unusual, non-repetitive patterns. It is also used when the raw material is too large or too wide to be physically inserted into an all-across press.
A perforated coil can be bound and shipped to the customer or moved to the next process once the perforating process is complete. The perforated sheets, on the other hand, may endure addition processes depending on their application, at the very least, cleaning and packing for shipment. Other finishing processes may be custom shearing into various shapes and sizes, rolling into cylinders or arches, welding, and forming into various shapes.
One process however that is rarely performed is painting. Stainless steel is designed for use without paint. Its surface is resistant to corrosion, rust, and discoloration and is rarely painted. Most paints will actually have difficulty adhering to the surface unless the surface has been sandblasted or roughed up and hand sanded.
Perforated stainless steel products are seen and used daily around the world. This product is used in many applications on the building and architectural front. It is renowned for its durability and strength, its longevity and ability to withstand the weather, as well as its pleasing appearance in aesthetic and decorative uses.
Many building facades has been designed to accommodate perforated stainless as a means of finishing the exterior. For instance, platforms and railings many times are designed using stainless steel. It is also popular with decorative accents and exterior stainless steel panels which allow light and air to pass freely while supplying a pleasing appearance.
Perforated stainless steel has infinite uses within the industrial as well as consumer markets. It is ideal for any products contacting liquids since it is resistant to rusting and corrosion. Liquid filtration, in particular, is a popular use for this amazing alloy. Perforated products in the food and medical industry are also produced in stainless steel for the same reason.
Stainless steel pipe resists bacterial growth just as it resists corrosion therefore making it the primary raw material for items that contact human consumables. It seems we can find perforated stainless steel all around us, in many instances right before our eyes throughout any given day.

Audio Effects-Noise Gate & Flange
Continuing the audio effects series, again, we all know of audio effects and what they generally are supposed to do. They are used to manipulate audio in ways that are not available with traditional playing and recording techniques. If youre like me, and enjoy dabbling in audio production, youre probably familiar with all the basic effects and maybe some other types.
Noise gate will be one of the topics of discussion today. Noise gate, what the heck is that? If that was your first reaction, youre not alone. Please dont worry; we will be demystifying this subject later on in the article. We will also be discussing flange, which is a more standard and widely used audio effect. So, in todays article we will be discussing both noise gate and flange effects, how they work and why they work the way they do.
Noise Gate
Basically, noise gate is a device or software logic that is used to manage the volume of an audio signal, in recording studios and in sound reinforcement. They are also used by musicians, in a portable form, to control amplification noise. At its most simple form it controls noise by only allowing sound to pass through it at a certain set threshold. Think of it as a literal gate; when the gate is open sound can pass, when the gate is closed no signal is allowed through.
More robust noise gate units have extra controls, I.E. attack, sustain, decay, release. This is so that you can further control the gating of your audio. Say youd like to have the gate applied in a hard fashion, you would set a short attack and a short release, so on and so forth. Noise gates are often used to isolate background noise from live recordings in order to eliminate them from the final copy.
Flange
Flange is related to the phasing effect produced by a, well, phaser effects unit. It is produced when two identical signals are mixed together, with one of the signals time-delayed by a small and gradually changing amount. The amount is usually equal to or less than 20 milliseconds. Peaks and notches are produced in the combined frequency spectrum, related in a linear harmonic series.
Part of the output signal is fed back in and resonates, intensifying the peaks and notches. This effect was originally generated with 3 three headed tape machines. Two of the tape machines would play the signal, obviously somewhat out of synch, and the third tape machine would record the output. The modern version of the effect is created using DSP (digital signal processing) technology.
This is the second part in my continuing series on audio effects. Today we discussed noise gate and flange, well be moving on some more advanced effects later on. I hope that this helped you all understand the basic functionality of these two effects, ultimately making your next foray into audio editing a bit less intimidating.
