Large diameter straight seam welded pipes and tubes

Large diameter straight seam welded pipe: also known as welded steel pipe, it is formed by bending steel plate or steel strip, the electric model is 0317. Inspection 8517611 standard, and then it is made by high frequency welding and submerged arc welding.
According to the weld form, it is divided into straight seam welded pipe and spiral welded pipe. According to the application, it is divided into general welded pipe, galvanized welded pipe, oxygen-blown welded pipe, wire casing, metric welded pipe, idler pipe, deep well pump pipe, automobile pipe, transformer pipe, electric welding thin-walled pipe, electric welding special-shaped pipe and spiral welded pipe. Large diameter welded pipe, etc.
General welded pipe: General welded pipe is used to transport low pressure fluid. The implementation of the standard GB/T0317 No. 8517611. Made of Q195A, Q215A, Q235A steel. Also available in other mild steels that are easy to weld. The steel pipe needs to be tested for water pressure, bending, flattening, etc., and has certain requirements on the surface quality. Usually, the delivery length is 4-10m, and it is often required to deliver to a fixed length (or multiple feet). The specification of the welded pipe is expressed by the nominal diameter (mm or inch). The nominal diameter is different from the actual one. The welded pipe has two kinds of ordinary steel pipe and thickened steel pipe according to the specified wall thickness.
