Stainless steel pipe fittings are pipe fittings in which the stainless steel pipe is inserted into the socket part of the pipe fitting and then argon arc welding is performed in a circle along the edge of the pipe fitting. It is the most reliable connection method among all the connection methods. Inner diameter of pipe fitting socket = outer diameter of pipe. According to the welded part of the pipe edge, it can be further divided into three kinds of pipe fittings: slope side extension, step side extension and no extension. The socket welding specification is generally DN15-DN100.
Butt welding type
Butt-welded stainless steel pipe fittings are pipe fittings made by argon arc welding along the butt seam of the stainless steel pipe and the pipe fitting. Generally, welding is required.
Outer diameter of pipe fitting socket = outer diameter of pipe.
Butt welding is generally used for welding of stainless steel piping systems with larger specifications.
