Threaded Pipe Fittings represent the oldest method of joining piping systems. Like Socket Weld Fittings, threaded pipe fittings are mainly used for small pipe diameters.Threaded piping is commonly used in low-cost, noncritical applications such as domestic water, fire protection, and industrial cooling water systems.Threaded fittings are normally made of cast gray or malleable iron, cast brass or bronze or forged alloy and carbon steel.

All Domestic Socket Weld Fittings are made from material forged and machined in USA. All fittings are supplied with MTR for full traceability.


    • A105 Carbon Steel: The standard forged carbon steel piping components for ambient and high temperature / pressure systems
    • S304 Stainless Steel: A common standard for stainless steel due to its malleability, high corrosive resistance weld-ability
    • SS316 Stainless Steel: A molybdenum stainless steel that provides excellent tensile, creep and stress-rupture strengths at elevated temperatures
