Product Description

Dn 1200/1800 large diameter spiral welding steel pipes

Spiral welded pipe: It is made by rolling low carbon carbon structural steel or low alloy structural steel strip at a certain helix angle (called forming angle) into a tube blank, and then welding the pipe seams. Strip steel produces large diameter pipes.

Spiral steel pipes are mainly used in water engineering, petrochemical industry, chemical industry, electric power industry, agricultural irrigation, and urban construction.
(1) For liquid transportation: water supply and drainage.
(2) For gas transportation: coal gas, steam, liquefied petroleum gas.
(3) For structural purposes: for piling pipes, for bridges.
(4) Pipes for docks, roads, and building structures, etc.
Spiral steel pipe is a spiral seam steel pipe made of strip steel coil as raw material, often warmly extruded, and welded by automatic double-wire double-sided submerged arc welding process.
