Stainless steel pipe fittings are pipe fittings in which a 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
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 fittings. Generally, welding is required.
The outer diameter of the pipe fitting socket = the outer diameter of the pipe.
Butt welding is generally used for welding large-sized stainless steel piping systems.
