Spiral welded pipe.
Compared with the straight seam welded pipe, the spiral welded pipe has higher strength and larger diameter. The production standard of the spiral welded pipe is more than that of the straight seam welded pipe. Mainly used in steel structure engineering, machinery manufacturing, construction water, oil pipelines and other low-pressure fluid pipelines, and can also be used in piling,structure and other construction fields.Product Name | Mild ssaw pipeline hot rolled round carbon spiral welded steel pipe for hydropower penstock | ||||
