PRODUCT DETAILS

The strength of spiral welded pipe is usually higher than that of straight seam welded pipe. It can use narrow blank to produce large diameter welded pipe, and can also use blank of the same width to produce welded pipe of different diameters. Commonly used for liquid delivery ( water supply and drainage ) and gas delivery ( natural gas, steam and liquefied petroleum gas).

Structure: such as piling pipes and Bridges; Wharf, road, building structure and other pipelines.
