Socket Weld Flange Supplier in India

Q: 1. What is a Socket Weld Flange, and how does it work?

A Socket Weld Flange (SW Flange) is designed with a recessed socket where the pipe is inserted before being fillet welded at the top. This flange provides a strong, smooth bore connection, reducing turbulence and improving flow efficiency. It is commonly used in small-diameter, high-pressure piping systems.

Q: 3. What are the different types of Stainless Steel Socket Weld Flanges?

Standard Socket Weld Flange – Most commonly used in pipelines Raised Face (RF) Socket Weld Flange – Enhances sealing performance Flat Face (FF) Socket Weld Flange – Used in low-pressure applications

Q: 5. What stainless steel grades are used for Socket Weld Flanges?

SS 304 / 304L – General-purpose corrosion resistance SS 316 / 316L – Superior resistance to chloride environments SS 321 – Good oxidation resistance at high temperatures SS 904L – Excellent corrosion resistance in acidic environments

Socket Weld Flanges – Top Manufacturer & Supplier in India

What is a Socket Weld Flange?

A Socket Weld Flange (SW Flange) is a type of pipe flange designed for small-diameter, high-pressure piping systems. The pipe is inserted into the flange’s socket and welded on the outside, creating a strong and leak-proof connection.

Socket weld flanges are widely used in industries requiring high strength, durability, and corrosion resistance, including oil & gas, chemical processing, power plants, and water treatment facilities. These flanges are typically manufactured using stainless steel grades such as SS 304, SS 316, SS 321, SS 347, SS 310, and SS 904L, ensuring long-lasting performance in harsh environments.
