Commonly used processing methods for non-standard straight seam welded steel pipes in industry

Forged steel: A pressure processing method that uses the reciprocating impact force of the forging hammer or the pressure of the press to change the blank into the shape and size we need.

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

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

Drawing steel: It is a processing method in which the rolled metal billet (profile, tube, product, etc.) is drawn through the die hole into a cross-section, and the length is reduced and increased. Most of them are used for cold processing.
