How many process methods for straight seamless steel pipe

Seamless steel pipe, with its high pressure taking, special process production, is now widely applied in various engineering projects. However, do you know how many process methods for straight seamless steel pipe? The primary processing methods of straight seamless steel pipe: Cast steel: A reciprocating impact by using forging hammer or press pressure would change the billet into the shape and standard we need. Kneading: The steel metal will be placed in a closed kneading, and one end of the pressure, so that the metal from the rules of the die hole and get the same shape and standard products processing methods, and more for the production of non-ferrous metal materials steel . Rolling: The steel metal blank through a pair of rotating roll gap (various shapes), because of the roll of the contraction of the data cross-section to reduce the length of the pressure processing methods. Pull the steel: It is to be rolled metal billets (type, pipe, products, etc.) through the die hole pull into the cross-section to reduce the length of the increase in processing methods are mostly used for cold-working.
