Hot dip galvanized spiral steel pipe is a hot dip galvanized spiral steel pipe made of strip steel coil as raw material, usually formed by warm extrusion, and welded by automatic double-wire double-side submerged arc welding process.The hot dip galvanized spiral steel pipe sends the strip into the welded pipe unit, and after rolling with multiple rollers, the strip is gradually rolled up to form a round pipe blank with an open gap. The amount of pressing down of the extrusion roller is adjusted so that the weld gap is controlled at 1~3mm and both ends of the welding joint are flush.

Galvanized spiral steel pipe is mainly used in tap water engineering, petrochemical industry, chemical industry, electric power industry, agricultural irrigation, urban construction, is one of the 20 key products developed in China.For liquid transport: water supply, drainage.For gas transmission: gas, steam, liquefied petroleum gas.For structural use: for piling pipe, for bridge;Pipes for wharves, roads, building structures, etc.
