Spiral steel pipe Accordingly, the spiral welded steel pipe is manufactured by welding rolled plate or strip steel using an automatic double-wire, double-sided submerged-arc welding process, and the pipe is formed through room-temperature extrusion. Spiral steel pipe The steel strip is fed into the welded pipe mill, where it is gradually rolled into a coil. It then passes through multiple sets of rolls, with the penetration of the extrusion rolls adjusted to form a circular tube blank with an opening gap, ensuring that both ends of the weld are flush and that the weld gap is maintained within one to three millimeters.
Spiral steel pipe It is primarily used in the petrochemical industry, municipal water supply projects, urban development, the power industry, the chemical industry, and agricultural irrigation. Spiral steel pipe For structural applications: wharves, bridges, roads, pile‑driving casings, and building‑structure pipes, among others. Spiral steel pipe For liquid conveyance: drainage and water supply. Spiral steel pipe For gas transport: liquefied petroleum gas, steam, and town gas.
