Product Paramenters
Spiral steel pipe is a spiral seam steel pipe made of strip steel
coils as raw materials, often extruded and formed by automatic
double-wire double-sided submerged arc welding. The spiral steel
pipe feeds the strip steel into the welded pipe unit. After rolling
by multiple rollers, the strip steel is gradually rolled up to form
a round tube blank with an open gap. The reduction of the squeeze
roll is adjusted to control the weld gap between 1 3mm, and make
both ends of the weld be flush.
Spiral steel pipes are mainly used in water supply engineering,
petrochemical industry, chemical industry, electric power industry,
agricultural irrigation, and urban construction. It is one of the
twenty key products developed in my country.
For liquid transportation: water supply and drainage. For gas
transportation: coal gas, steam, liquefied petroleum gas. For
structural purposes: as piling pipes and bridges; pipes for docks,
roads, and building structures.
