Piling press with straight seam mild steel pipe production process can be divided into high frequency straight seam submerged arc weld steel pipe and straight seam steel pipe. Submerged arc welding and straight seam steel pipe according to the different forming methods is divided into UOE, RBE, JCOE steel pipes, etc. According to purpose is different, and different production working procedure, after. (can be roughly divided into the scaffold tube, fluid pipe, wire casing, stent tube, guardrail tube etc) DSAW steel pipe of the main processing methods are:
Forging steel: use the reciprocating impact or press pressure forging hammer to make blank as we need to change shape and size of a pressure processing method.
Extrusion: steel metal is placed within the closed extrusion Jane, pressure on the side, make the metal from rules of extrusion die and have same shape and size of the finished product processing method, used in the production of non-ferrous metal material products.
Rolling: steel metal blank through a pair of rotating roll gap (shape), due to the compression of roll reduce material section, the length of the increase of pressure processing method.
Drawn steel: it is already rolling metal blank (type, tube, products, etc.) through the die drawn into section reduced length increased processing methods are mostly used in cold working.
