Socket Weld Flange manufacturer

EN 1092-2 PN16 SWRF Flange, Carbon steel socket weld flange ansi b16.5 manufacturer in India

ANSI B16.5 class 150 socket weld flanges uses grades like F304, F304L, F321, F321H and many more. These are used in industries like oil field and power plant, and in many other applications. These are available in various sizes and are in huge demand in the market. Reducing socket weld flanges are of smaller size and it allows a smooth flow of liquid or gas inside the pipe. This is having various grades and based on that the product is manufactured. This is most durable and gives excellent performance.

Socket weld flange dimensions consist of many parameters like class, diameter, thickness, height, stud bolts and many more. Based on this dimensions, the product is manufactured. This is used in applications like pipeline industry, steam, air, gas and oil. There are various types of socket weld flanges. Those are as given below:

  • 1. Lap joint flange
  • 2. Threaded flange
  • 3. Blind flange
  • 4. Stub end
  • 5. Slip on flange
  • 6. Welding neck flange

These are some of the types which are available in the market. SS socket weld flanges are perfect corrosion resistance and has good weldability. These are a bit expensive compared to slip on flange. The dimensions of this include various parameters like diameter, thickness, height, holes and many other factors are included. 300# socket weld flange is the one where high quality raw materials are used and are manufactured accordingly. Various other grades are also available.

What is Stainless Steel Socket Weld Flanges ?


Socket weld flanges are used on smaller sizes of high pressure pipes. These are the one which are inserted on a pipe and these are provided with raised face, flat face or RTJ facing. These are designed for high pressure and small diameter pipeline. These are used in industries such as chemical, and many other allied industries. Stainless steel socket weld flanges are manufactured by using quality raw materials and they are the one where it is used to block the end of a pipe system or valve. This is having its own dimensions and specifications.
