Welded pipe production line (English name: Welded Tube Mill) alias straight seam welded pipe production line is the material (same or different) of the workpiece to be welded, through heating or pressure or both, and with or without filling materials, so that the material of the workpiece reaches The process of bonding atoms together to form a permanent connection.

Tube pipe process
Raw material decoiling – leveling – end shearing and welding – looper – forming – welding – inner and outer bead removal – pre-calibration – induction heat treatment – sizing and alignment – eddy current testing – cutting – hydraulic inspection – pickling – final inspection (Strict control) – packaging – shipment.
Features:The production process of straight seam welded pipe is simple, the production efficiency is high, the cost is low, and the development is rapid. The strength of the spiral welded pipe is generally higher than that of the straight seam welded pipe, and the welded pipe with a larger diameter can be produced with a narrower billet, and welded pipes with different diameters can be produced with the same width billet. But compared with the straight seam pipe of the same length, the weld length is increased by 30~100%, and the production speed is lower.
General welded pipe: general welded pipe is used to convey low pressure fluid. Made of Q195A, Q215A, Q235A steel. It can also be manufactured from other mild steels that are easy to weld. Steel pipes are subject to water pressure, bending, flattening and other tests, and have certain requirements for surface quality. Usually, the delivery length is 4-10m, and it is often required to deliver in fixed lengths (or double lengths). The specification of the welded pipe is represented by the nominal diameter (mm or inch). The nominal diameter is different from the actual one. The welded pipe has two types of ordinary steel pipe and thickened steel pipe according to the specified wall thickness. The steel pipe is divided into two types: threaded and unthreaded according to the pipe end form.
