Stainless steel pipe fittings are a type of pipe fitting, made from stainless steel material, hence the name. They include items such as stainless steel elbows, tees, crosses, reducers, and caps. Based on the method of connection, they can be categorized into four types: socket weld stainless steel fittings, threaded stainless steel fittings, flanged stainless steel fittings, and welded stainless steel fittings. Stainless steel elbows are used in areas where the pipe needs to turn; flanges are used for connecting pipes to each other, mounted at the pipe ends. Stainless steel tees are used where three pipes converge; stainless steel crosses are used where four pipes meet; and stainless steel reducers are used where two pipes of different diameters connect. Main stainless steel grades: 304, 304L, 316, 316L.
