Stainless Steel Socket Weld Flanges

Leading Manufacturer of ASME 16.5 socket weld flange in India, Provides Dimensionally Accurate Product


Stainless Steel Socket Weld Flanges


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. .

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.
