By Industry
Straight seam steel pipe main processing methods are:
Forged Steel: using a reciprocating hammer impact force or pressure presses the blank changed into the desired shape and size our a pressure processing method .
Extrusion : the steel of the metal simple squeeze on the closed , the pressure applied to one end of the metal from a predetermined hole in the extrusion mold to obtain a finished product with the shape and size of the processing method used for production of non-ferrous metal steel .
Rolling : a steel metal blank by a pair of rotating rolls gap ( various shapes ) , due to compression of the material roll reduced cross-section , the length of the increased pressure processing method .
Pullout Steel: is already rolled metal blank ( type , tubes, products, etc. ) through the die hole pull aside into a reduced cross-section to increase the length of the processing methods are mostly used as a cold .
