Non-standard Straight Seam Welded Steel Pipe Processing Method

Forging steel: 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 require.

Extrusion: It is a steel processing method in which metal is placed in a closed extrusion cylinder and pressure is applied on one end to extrude the metal from a specified die hole to obtain a finished product of the same shape and size. It is mostly used to produce non-ferrous metals and steel.

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

Drawing steel: The rolled metal blank (shaped, tube, product, etc.) is drawn into a cross-section through the die hole, and the processing method to reduce the length increase is mostly used as cold processing.
