The socket argon arc welded pipe fittings developed by Minle Company is a national patent product, which highlights the characteristics of the physical properties of the material in the design of the socket. It forms an obtuse angle with the straight pipe of the socket and is connected in an arc shape, which can avoid the stress concentration caused by thermal expansion after the pipe is inserted into the pipe and causes the welding socket to crack. The finished pipe fittings are internally and externally polished by a magnetic polishing machine developed and designed by our company, which can make the inner and outer walls of the pipe fittings smooth and enhance the corrosion resistance of the pipeline.
