China Lh800-1220-12 Steel Pipe Spiral Welding Machine of API Standard

Introduction:
A spiral pipe mill is a series of machines used to roll steel strips by a certain angle and produce spiral welded pipes.
A front swing type spiral pipe mill is the typical traditional spiral pipe mill. It operates uncontinuously but has the advantage of low investment, compact design and capability of extra-length pipe production.
This 1200mmx12mm (B= 800mm) front swing type spiral pipe welding machine is designed and manufactured by our high-tech institute with advanced national and international technology. It has been found to completely meet with the API-5Lx standards by advanced design, reliable performance, light weight and economical investment.
