Industry-leading straight seam pipe production technology

 

1. High frequency straight seam welded pipe (ERW)

Straight seam high-frequency welded pipe is a welded pipe that is continuously produced on the production line using steel strip (coil) as the raw material and high-frequency welding technology.

The material strength is generally below 450MPa, and the materials include J55, L450, X60, Q235, Q345, Q420, Q460. The diameter range of the longitudinally welded pipe is 14-610mm, and the wall thickness is 1-23.8mm.

Straight seam steel pipe high frequency welded pipe adopts multi-frame continuous forming process, high production efficiency (production speed 15-40m/min), the production line has complete sizing, straightening, rounding and other equipment, and the steel pipe is in roundness, straightness and The welding aspect is better.

 

2. Submerged arc straight seam welded pipe (LSAW)

Submerged arc longitudinal seam welded pipe is produced by using a single steel plate as raw material, through JCO or UOE forming, submerged arc welding or submerged arc welding combined with other welding processes. Common ones are X70, X80, X120, etc. The diameter of LSAW pipe is 400-1422mm and the wall thickness is 8-44.5mm.
