Product Description
Longitudinal welded pipe has simple production process, high production efficiency, low cost and rapid development. The strength of spiral welded pipes is generally higher than that of straight seam welded pipes. A narrower blank can be used to produce welded pipes with larger pipe diameters, and a billet with the same width can also be used to produce welded pipes with different pipe diameters. However, compared with the straight seam pipe of the same length, the weld length is increased by 30-100%, and the production speed is lower. Generally welded pipes are used to transport low-pressure fluids. Made of Q195A, Q215A, Q235A steel. It can also be made of other mild steel that is easy to weld. Steel pipes need to be subjected to water pressure, bending, flattening and other experiments, and there are certain requirements for surface quality. Usually the delivery length is 4-10m, and fixed-length (or double-length) delivery is often required. The specifications of welded pipes are expressed by nominal diameter (mm or inches). The nominal diameter of welded pipes is different from the actual ones. According to the specified wall thickness, welded pipes can be divided into ordinary steel pipes and thickened steel pipes. The steel pipes are divided into threaded and non-threaded types according to the tube end.
