Suggestions for High Quality Development of HFW Pipe Manufacturing Technology

Described here in the paper is the current development situation of domestic HFW pipe manufacturing technology. It is pointed out that under the current situation，enhancing the manufacturing efficiency and high quality development is very important to expansion and improving competitiveness of the product. And it is an effective approach to promoting high quality pipe manufacturing via relevant analysis and exploitation the progresses involving such core HFW pipe-making techniques as formation，welding，controlling，heat treatment and inspection/testing，etc. Furthermore it is emphasized in the paper that strengthening the research and application of critical manufacturing technologies，control and inspection/testing techniques of the HFW pipe manufacture will significantly speed up the high quality development， and improvement of manufacture and competitiveness of the said weld pipe.
