Stainless steel pipe fittings are pipes that are inserted into the pipe socket portion and then argon-arc welded along the edge of the pipe. They are the most reliable connection method for all connection methods. Pipe fitting diameter = pipe outer diameter. The welded part according to the edge of the pipe can be further divided into three kinds of pipe fittings: the edge of the slope, the edge of the step and the section without the extension. The welding specifications of the socket are generally DN15-DN100.
