There are many processing methods for non-standard
straight seam welded pipes. Still, for non-standard straight seam welded pipes, more attention is paid to the strict control of the production process of high-quality and durable non-standard straight seam welded pipes, rather than the non-standard straight seam welded pipes. What are the processing methods?
Forging steel: a pressure processing method that uses the reciprocating impact force of a forging hammer or the pressure of a press to change the blank into the shape and size we need.
Extrusion: It is a processing method for steel to place metal in a closed extrusion box and apply pressure at one end to make the metal extrude from the specified die hole to obtain a finished product with the same shape and size. It is mainly used for the production of non-ferrous metal steel.
Rolling: A pressure processing method in which the steel metal billet passes through the gap between a pair of rotating rolls (various shapes), and the cross-section of the material is reduced and the length is increased due to the compression of the rolls.
Pulling steel: the processing method of drawing the rolled metal blank (type, pipe, product, etc.) through the die hole into a section, reducing the length, and increasing the length is mostly used for cold working.
