Advanced testing equipment and high-standard physical and chemical laboratories are the reliable guarantee of product quality. The main products are spiral steel pipe, Zhongyuan spiral welded pipe, spiral welded pipe, spiral seam double-sided submerged arc welded steel pipe, anti-corrosion steel pipe and so on. At the same time, our company is also a relatively well-known Hebei spiral steel pipe factory and Cangzhou spiral steel pipe factory.
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.
