Product Description
The spiral steel pipe is a spiral seam steel pipe with strip coil plate as raw material, often warm extrusion forming, and welded by automatic double-wire double-sided submerged arc welding process. The spiral steel pipe sends the strip steel to the welding pipe unit, and rolls up the strip gradually to form a circular tube blank with open gap through multi-channel roll rolling. The pressure of the extrusion roll is adjusted to control the weld gap between 1 to 3mm, and the two ends of the welding joint are flush.
| Basic infor mation: | Spiral welded pipe: It is made by rolling low-carbon carbon structural steel or low alloy structural steel strip into a pipe blank at a certain helix angle (called forming angle), and then welding the pipe seam to produce large-diameter steel pipes using narrower strip steel. |
