Pipe fittings is mainly used to connect, control and support the pipe system in the pipeline system, and welding pipe fittings mainly connect with pipe by the way of the hot-melt welding. The new welding pipe fittings, include the new shape of the pipe fittings, the column indications in the pipe wall and the concave surface from outside the pipe wall to inside. The new design patent of hot wheels style, the column indications showing the function of Pipe fittings and the design of concave to solve the problem of the melt residues by hot-melt welding are the three new characteristics of this new pipe fittings.
