What are Duplex & Super Duplex Socket Weld Flanges?

Socket Weld Flanges are designed with a recessed socket or shoulder into which the pipe is inserted before welding. The pipe is positioned inside the flange socket, and a fillet weld is applied around the outer circumference to create a secure and leak-proof connection.

Socket Weld Flanges are commonly used in small-diameter, high-pressure piping systems where reliability, structural integrity, and excellent sealing performance are essential.

Duplex Socket Weld Flanges are manufactured using Duplex Stainless Steel grades featuring a balanced ferritic-austenitic microstructure. This combination provides excellent mechanical strength, superior resistance to chloride attack, and outstanding resistance to stress corrosion cracking.

Super Duplex Socket Weld Flanges contain higher amounts of chromium, molybdenum, and nitrogen, offering enhanced resistance to pitting corrosion, crevice corrosion, seawater corrosion, and aggressive chemical environments.

At Maruti International, we manufacture premium-quality ASTM A182 Duplex Socket Weld Flanges and ASTM A182 Super Duplex Socket Weld Flanges for demanding industrial applications worldwide.
