    Description

    1.Spiral steel pipe is a spiral seam steel pipe made of strip steel coil as raw material, often extruded at temperature, and welded by automatic double-wire double-sided submerged arc welding process.

    2.The spiral steel pipe feeds the strip steel into the welded pipe unit, and after rolling through multiple rolls, the strip steel is gradually rolled up to form a round pipe blank with an open gap, and the amount of pressure of the extrusion roller is adjusted to control the weld gap at 1~3mm, and the two ends of the weld are flush.

    3.Spiral steel pipes are mainly used in water engineering, petrochemical industry, chemical industry, electric power industry, agricultural irrigation, urban construction, and liquid transportation: water supply and drainage. For gas transportation: coal gas, steam, liquefied petroleum gas. For structural purposes: as piling pipes, bridges; Pipes for docks, roads, and building structures.
