Stainless steel pipe fittings belong to one kind of pipe fittings, it is made of stainless steel material so called stainless steel pipe fittings, it includes: stainless steel elbow, stainless steel tee, stainless steel tee, stainless steel four-way, stainless steel different diameter pipe, stainless steel pipe cap, according to the connection method can be divided into socket stainless steel pipe fittings, threaded stainless steel pipe fittings, Four types of steel pipe fittings and welded stainless steel pipe fittings. Stainless steel elbows are used where the fittings turn; flanges are used where the tubes and pipes are connected to each other, at the end of the pipe; stainless steel tee pipes are used where the three pipes converge; stainless steel tee pipes are used where the four pipes converge; and stainless steel pipes with different diameters are used where the two pipes are connected. Main stainless steel material: 304, 304L, 316, 316L
