ASME B 16.47 is one of the American standards. It refers to one of the large-diameter steel flanges. The standard also covers the requirements about flange joint, flange bolting, flange gaskets, etc. In addition, the standard covers the design of flanges from NPS 60 to NPS 24. With the rating classifications 900, 600, 400, 300, 150, and 75, the standard ASME B 16.47 offers measurement, dimensions, marking, tolerances, and pressure temperature for the pipe flanges. ASME B16.47 standard comes in two series, Series B and Series A flanges. The differences between these flanges are: Characteristics ASME B16.47 Series A flanges are relatively thicker, heavier, and more robust than Series B flanges with the same size and pressure ratings. Hence, series A flanges can withstand extra external loading compared to the Series B flanges. Required Fasteners The fastener quality requirement for ASME B16.47 Series A flanges is lesser than the Series A. Class 150 Series A flange requires 28 bolts of 1...

Stainless steel flange   is used widely in industrial and domestic applications because of its many benefits. It is resistant to corrosion alongside the temperature looks good. The flanges made of stainless steel also offer all these benefits and much more. Flanges are an essential part of the piping valves, contractors, and other types of equipment. However, the best they offer is to provide a repair, cleaning, and access point. In a closed system, a  flanged joint   is made by bolting the gasket together, which you can flank by two flanges, resulting in a stronger seal. Here are a few benefits of choosing  stainless steel flanges : Strength Stainless steel is durable and strong, and it is one reason that it can withstand enormous pressure. On the other hand, aluminum may prove a much cheaper option. The reason is that it is soft and cannot work under high pressure. Corrosion Chemical, rust, and other factors are easily damageable metals. Therefore, when you choose ...

The flange is a structure extension that has holes drilled into it. These holes are placed in the flange to accommodate the securing bolts. The flange joins or seals the various part of the structure. Here are a few main elements of the flange. These are: Flange dimensions Each flange ASME B16.5 comes with many standard dimensions. So if a draftsman in the US, a work preparer in Japan, or a pipefitter in Australia is speaking about the welding neck flange 6″-150#-S40 ASME B16.5, it may go over the flange. If the flange is ordered, the supplier would like to know the material quality. Like, ASTM A105 is one of the forged carbon steel flanges, while A182 would be a forged stainless steel flange. Flange applications The flange’s purpose depends on its design. The main reason is to increase the structure’s strength, like in the case of an iron beam. These are often useful in the construction of buildings and houses. You can use the flange as a guide to keeping a particular object in place....

Weld neck flanges are useful extensively for all types of pipe systems. However, industrial long weld neck flanges are taken as the best option when the pipes are transferring high-pressure or high-temperature fluids or fluids that fluctuate in temperature. It is true, especially in the gas and oil industry. How to choose long weld neck flanges? Industrial long weld neck flanges offer additional reinforcements which standard  weld neck flanges  do not offer. The long neck guides the pipe into the flanges, providing them with extra strength. The extra assurance helps ensure the structure, environment safety, and people when high-pressure and high-temperature fluids are involved. The structural reinforcement provided by an industrial long weld neck flange is crucial to the stability and safety of high-pressure industrial and commercial systems. How long do weld neck flanges help? There are a few uses of weld neck flanges: Large pipe networks Be it water main, gas main, or anothe...

There are many kinds of flanges available in the market like blind flanges , butt weld flanges, slip-on flanges, weld neck flanges, and more. Here in this blog, we’ll discuss slip-on vs. plate flanges. Meaning of plate flanges Plate flange is a circular, flat disc welded to the pipe’s end. It enables the flange to be bolted to another pipe. It is often referred to as the flange slip, plane flange, flat flange, etc. Two plate flanges can be bolted together with a gasket in between them, usually used in water and fuel pipelines. The pipe length is not always known while constructing a pipeline. The plates may also be welded with a slight bias to the shaft, allowing the two pipes not to match up and join. Plate flanges come with a notched finish on the inner mating surface that allows the plate to fit within the gasket material. In any given dimension, plate flange designs are standardized, apart from the materials used to manufacture them. It ensures that the fit is exactly like a 6-inc...

If you want to know why do forging flanges need heat treatment, you must first get an understanding of the meaning behind forgings. Forging is the use of a hand hammer, pressure equipment, or forging hammer on the mold on the heating of the metal blank force so that metal materials under the condition of non-separation plastic deformation obtain performance, size, and properties meet the requirements of parts. Need of heat treatment for the forged flange The main purpose is to refine the coarse grains, eliminate the residual stress and work hardening, reduce the hardness, improve the cutting performance, prevent the white spots while forging, and make sure about the required machinery and metal structure. Now, below are details about the heat treatment: Normalizing If you want to forge flange connections , heat treatment is the first step. Heat the forgings above the transformation temperature, form a single austenite structure, after a period of uniform temperature stability, after a ...

Bolted flange assemblies are helpful to connect widely with different elements of the pipelines and pressure vessels. They carry process media at temperatures that vary from cryogenic to more than 1000°C. Thermal transitions and high temperatures play a vital role in the tightness of bolted flange assemblies. We can quickly encounter the unfulfilled tightness that may occur due to thermal effects. It becomes easier if the assembled components (gaskets, bolts, and flanges) are in limits, and do not undergo mechanical failure. Characterize the temperature effects The temperature during the process is bound to rise. It demands the improvement in the chemical efficiency that drives the process. It is why; components like gaskets must be able to withstand the increase very quickly. Characterizing the temperature effects on the flange bolting assemblies will always remain a crucial issue. Not only for the end-users but also for the designers as it involves complex physical laws. The reason ...

There are numerous essential variables purchasers ought to consider when picking pipe fittings. The materials used to construct a pipe fitting helps identify how the fitting will connect to the pipes and the pressure it can handle. Therefore, it's imperative to choose the right pipe fittings for the project despite their size. To fix the right pipe system, you should know the different types of fittings available and their properties. Here are flange fittings that can help you find a solution. Knowing the Different Types Will Help to Find the Right Pipe Flange: 1. Threaded flanges 2. Blind Flanges 3. Alloy pipe flanges Threaded flanges: These types of flanges are used in low-pressure systems. The most mainstream threaded flanges range in ½ inch to 6" standard size, yet many offer NPT threaded flanges up to 24" if necessary. These flanges are not suitable for welding temperature, which is more than 260 ℃and less than -45 ℃ of the pipeline.             ...

What to look at before beginning the installation? Accessories or connections for the flange: Properly introduced flanged connections give progress fitting to join substitute funneling materials, a mechanical way to interface with valves and other hardware, and join channeling frameworks where continuous destroying might be required. The notched substance of the flange gives a fluid-tight seal on the gasket when flanges are appropriately gathered, upheld, and legitimate torque is applied to the bolts. Gaskets: Full face 1/8" thick elastomeric material with a Shore A Durometer hardness of 50-70; gasket material is chosen should be viable with application and liquids passed on. Varieties in a gasket material and shore hardness may influence the fixing torque required. Dimensions of the flange :   Dimensions are more than after according to the ANSI Flange dimensions . Flange ring bolt opening dimensions adjust to ANSI B 16.5 Class 150 bolt design. Strung flange center points ...

A valve is a mechanical device in a piping system used to control the flow and pressure of contents – liquid, oil, vapors, or gas. Here is a list of 5  standard valves that every oil and gas engineer should know: #1. Ball valves It's a rotary motion quarter-turn valve. It uses a ball-shaped disk to control the flow of components flowing in the piping system. When you open the valve, the ball's holes come in line with the body inlet, allowing contents to pass. The ball valves can withstand a temperature between - 200 deg C and as high as 500 deg C. the best thing about this valve is that it’s a quick-acting type. Some of the different types of ball valves include: ·           Floating ·          Trunnion Mounted ·          3 Way ·          Top entry ·          Side en...
