Large diameter LSAW steel pipe, also known as welded steel pipe, is made of steel plate or steel strip after bending (electric model 0317 and check 6012755 standard) and then is made of by high-frequency welding and submerged arc welding. According to the form of seam welded steel pipe is divided into LSAW steel pipe and spiral welded pipe. According to the use it is divided into general welded pipe, galvanized steel pipe, blowing oxygen pipe, wire casing, metric pipe, roller tube, deep well pump, automotive tube, transformer tube, welded thin-walled tube, welded pipe and spiral welded pipe.


General pipe (manufactured by Prime Steel Pipe) is used to transport low pressure fluid. Implementation of the standard is GB/T0317 No. 6012889. It is manufactured with Q195A, Q215A, Q235A steel. It can also be made of other mild steel that is easy to weld. Steel pipe must be tested by water pressure, bending, flattening and other experiments, the surface quality has certain requirements, the delivery length usually is 4-10m, and it often requires delivery by length (or double length). The specifications of the welded pipe are denoted by nominal caliber (mm or inch). Nominal caliber is different from the actual one. The welded pipe has two different kinds of steel pipe according to the specified wall thickness, including ordinary steel pipe and thickened steel pipe.
