Stainless steel socket fittings are a type of socket fitting, which are pipe connecting components machined from stainless steel round bars or ingots after forging.

Its connection form is Socket Welding-SW, where steel pipes are inserted into socket holes for welding. The main manufacturing standards are ANSI/ASME B16.11, HG/T 21634, MSS SP-83, MSS SP 79, and GB/T 14383-2008.

The types of stainless steel socket fittings include 45° elbows, 90° elbows, tees, cross tees, 45° slotted tees, double socket ferrules, single socket ferrules, pipe caps, swivel joints, and branch supports, etc. Among them, the tees and cross tees come in both equal and unequal diameters; similarly, the double socket ferrules are also available in equal and unequal diameters, with the unequal diameter ones further divided into concentric and eccentric types.
