| Synopsis: The new manufacturing processes for seamless steel pipe and REW steel pipe have been developed. The manufacturing concept of the developed steel pipe and its characteristics are summarized as follows. (1)Hight efficient manufacturing technologies for high alloy steel seamless tube and pipe have been established by Mannesmann rolling process. (2)New martensitic stainless steel seamless pipes with superior corrosion resistance have been developed. (3)New ERW forming mill for stainless steel pipes with excellent formability habe been developed. (4)High quality ERW pipe products have been produced by manufacturing technology for medium diameter ERW linepipe and square steel pipe. |
