Carbon steel spiral welded pipe

Carbon steel spiral steel pipe is made by rolling low-carbon carbon structural steel into a tube blank according to a certain helical angle, and then welding the pipe seams. It can use narrow strip steel to produce large-diameter steel pipes. The main materials are q195, q235A, q235B, q345 and so on. Spiral welded pipes are single-sided welded and double-sided welded. The welded pipes should ensure that the hydraulic test, the tensile strength of the weld and the cold bending performance must meet the regulations. Carbon steel spiral steel pipe is mainly used in drainage and water supply projects, fluid liquid, and solid conveying pipelines. It is widely used in urban construction and municipal engineering.
