Processing methods of LSAW steel pipe:

1 Forging : a pressure processing method that uses the reciprocating impact of a forging hammer or the pressure of a press to change the blank into the shape and size we need.

2 Extrusion: It is a processing method in which the steel puts the metal in a closed extruder and applies pressure at one end to extrude the metal from a prescribed die hole to obtain a finished product with the same shape and size. It is mostly used for the production of non-ferrous metal materials.　　

3 Rolling: A pressure processing method in which a steel metal billet is passed through a gap between a pair of rotating rolls (various shapes), and the cross-section of the material is reduced due to the compression of the rolls and the length is increased. 　　

4 Drawing steel: It is a processing method in which rolled metal blanks (forms, tubes, products, etc.) are drawn through a die hole to reduce the cross-section and increase the length, which is mostly used for cold working.
