What are the Benefits of Choosing Stainless Steel Flanges?

Image
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 ...

Plate flange vs Slip-on Flange

Image
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...

Why Do Forging Flanges Need Heat Treatment?

Image
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 ...

When Do We Use Slip-On Flange, A Weld Neck Flange Or A Lap Joint Flange

Image
There are few types of flanges , but the most used types by ASME B16.5 are weld neck, slip-on, and lap joint flange. Weld Neck Flange These are easy to recognize at the long tapered hub. It goes gradually over to the thickness of the wall from a fitting or pipe. The long tapered hub provides an essential reinforcement for use in several applications that involve elevated, sub-zero temperatures or high pressure. The smooth transition from fitting or pipe wall thickness to flange thickness gets affected by the taper and is extremely beneficial under the conditions of repeated bending caused by the line expansion or other variable forces.   Slip-on Flange The calculated strength from a slip-on flange under internal pressure is of around two-thirds of the Welding Neck flanges, and their life under fatigue is about one-third that of the latter. The connection with the pipe is about 2 fillet welds, as well at the outside as also at the inside of the flange. Lap Joint Flange Lap Joint Fla...
