The Production & Quality Control Flow Chart For Pipe Butt-Welding Fittings

The butt welding fittings are commonly made from two kinds of raw material:

1. Made from the steel pipes, it maybe the seamless pipes ,or welded pipes . The production method of both pipes are same.

2. Made from the steel plate, for example , the steel pipe cap, is made from the steel plate. Other big size pipe fittings which is not available to produce from a pipe is also made from steel plates, so it is not seamless pipe fittings, it need to be welded from the steel plates.
