Offline spiral pipe welding plant with PERFECT arc®

Zhejiang Kingland uses its offline spiral pipe welding plant to produce pipes to API 5-L PS2 standard with an outside diameter of 20 to 64 inches and wall thicknesses of 6.4 to 25.4 millimeters.

To achieve exceptional results, the new plant comprises a spiral pipe forming and tack-welding machine for forming and pre-welding hot rolled steel strip. It also features three downstream offline finish-welding stands. Additionally integrated is PERFECT arc® which ensures the line meets our Ecoplants sustainability criteria. That saves up to 30 percent energy compared to competitor plants.
