2021 China New Design Galvanised Pipe Suppliers - Spiral steel pipe – Hongmao Detail:
Product Introduction
Spiral steel pipe is made of strip coil as raw material, extruded at regular temperature and welded by automatic double wire double submerged arc welding process. The spiral steel pipe will feed the strip into the welding tube unit, and the strip will be rolled up gradually to form a circular tube blank with open gap after rolling by multiple rolls. The pressure down of the extrusion roll will be adjusted so that the weld gap is controlled within 1~3mm and both ends of the welding joint are flush.
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 transportation: water supply, drainage. For gas transportation: gas, steam, liquefied petroleum gas. For structural use: for piling pipes, Bridges; Pipe for wharf, road, building structure, etc
