Standard for inspection of stainless steel pipe fittings tee

　　Stainless steel pipe fittings belong to one kind of pipe fittings. They are made of stainless steel material. They include stainless steel elbows, stainless steel tees, stainless steel tees, stainless steel cross, stainless steel pipe with different diameters and stainless steel pipe caps. According to the connection method, they can be divided into socket stainless steel pipe fittings, threaded stainless steel pipe fittings, flanged stainless steel pipe fittings and Stainless steel tees are used for turning parts; flanges are used for connecting pipes to pipes; stainless steel tee pipes are used for converging places of three pipes; stainless steel tee pipes are used for converging places of four pipes; stainless steel differential pipes are used for connecting places of two pipes with different diameters. Main stainless steel materials: 304, 304L, 316 |, 316L.
