Product Description
Product Overview
Our Forged Steel Socket Weld Flange is produced in accordance with ANSI/ASME B16.5 standards, offering a high-strength, leak-proof connection for small-bore, high-pressure piping systems.
The socket weld design allows the pipe to be inserted into the flange’s recessed area and fillet-welded around the outside, ensuring accurate alignment and smooth bore flow. Available with Raised Face (RF) and Ring Type Joint (RTJ) sealing surfaces, these flanges are ideal for use in oil & gas, petrochemical, chemical processing, power generation, and water treatment industries.
Manufactured from high-quality forged carbon steel and stainless steel (304/316), our socket weld flanges provide excellent durability, corrosion resistance, and pressure-handling capability.
