【Abstract】 The working procedure and the principle of its mills of LSAW steel pipe processed by the method named UOE are introduced in this paper.Applying the pre-established forming process,the steel pipes with dimension of Ф711mm×15.9mm×12200mm have been produced tentatively.The data(including diameter,thickness and ovality of steel pipe,which have been measured from the test production)show that the preassigned forming process is reasonable for the batch production of the steel pipes with the dimension mentioned above.更多还原
