Socket Weld Flanges are used for small-size and high-pressure piping that do not transfer highly corrosive fluids.This due to the fact that these flange types are subject to corrosion in the gap area between the end of the pipe and the shoulder of the socket.Their static strength of socket weld flanges is similar to slip-on flanges’, but their fatigue strength is higher due to the presence of a single, instead of double, fillet weld

Why Choose Our Socket Weld Flanges?

• Exceptional Value: Our socket weld flanges offer strong performance at a competitive price.
• Robust Construction: Designed to handle high pressure and temperature, these flanges are suitable for demanding applications in the petroleum, chemical, natural gas, and power generation industries.
• Material Options: Available in a variety of materials, including 304, 304L, 316L stainless steels, and high-strength alloys like 2507, 2205, TP310S, and TP321 to suit your needs.
• Standards-Compliant: Manufactured to comply with standards such as GB/T9119-2010, HG/T20592-2009, HG/T20615-2009, DIN, ASME, BS, and JIS.
• Enhanced Strength: With static strength similar to slip-on flanges and improved fatigue resistance due to a single fillet weld, our socket weld flanges offer durability.
• Space-Efficient Design: Ideal for small piping systems, where space is limited but high performance is required.
