. Basic information of spiral steel pipe
Strip coil spiral steel pipe is a spiral seam steel pipe welded by automatic double-wire double-sided submerged arc welding process using strip coil as raw material, regular warm extrusion molding.
Spiral steel pipes for water supply projects are mainly used in water supply projects, petrochemical industry, chemical industry, electric power industry, agricultural irrigation, and urban construction.
Used for water supply and drainage for liquid transportation. For gas transportation, coal gas, steam, and liquefied petroleum gas are used. It is used as piling pipes for structures, pipes for bridges, wharves, roads, building structures, etc.
Spiral steel pipes for sewage treatment, spiral steel pipes for water purification, spiral steel pipes for water plants, spiral steel pipes for power plants and chemical companies, spiral steel pipes for nuclear power, spiral steel pipes for transporting flammable fluids, spiral steel pipes for transporting non-flammable fluids Steel pipes are mainly used in the petroleum and natural gas industries to transport flammable and non-combustible fluids and steel structures.
