Spiral steel pipe is a spiral welded steel pipe made of coiled plate or strip steel as raw material and welded by automatic double-wire double-sided submerged arc welding process, and the pipe is often extruded at high temperature. The spiral steel pipe feeds the strip steel into the welding pipe unit, and the strip steel is gradually rolled up, rolled by multiple rollers, and the reduction amount of the extrusion roller is adjusted to form a circular tube blank with an opening gap, and make the two ends of the welded joint flush. , so that the weld gap is controlled between one and three millimeters.

Spiral steel pipes are mainly used in petrochemical industry, water engineering, urban construction, electric power industry, chemical industry, and agricultural irrigation. Spiral steel pipe is used for structure: wharf, bridge, road, piling pipe, building structure pipe, etc. Spiral steel pipe is used for liquid transportation: drainage and water supply. Spiral steel pipe is used for gas transportation: liquefied petroleum gas, steam, coal gas.
