We are the design and manufacture base of welded pipe equipment. The production lines supplied by us include discontinous production line and continous production line. We are capable of designing and manufacturing one step formation and two-step formation. The finishing line is arranged as per AP2 standards in order to perform the diameter expansion at pipe ends, facing and chamfering, hydrotest and NDT etc. We are capable of designing and manufacturing spiral welded pipe mill wit one step formation and tacking & final welding formation.
Spiral welded pipe mill is mainly designed for producing the line pipes for conveying petrolium and natural gas.
The spiral welded pipe mill supplied by our company is relatively flexible in operation and convenient for changing and adjusting pipe catagories.
Under the same conditions, the pressure resistance of the welding seam of spiral pipes is higher than that of longitudinal welded pipes.
