Large Diameter Thick Wall Spiral Steel Pipe

Spiral welded pipe is to roll the low carbon structural steel or low alloy structural steel band to pipe blank with certain spiral curve (forming angle), then weld the seam to form the finished product. We can use narrow steel band to produce large diameter steel pipe. Spiral welded pipe is mainly used in petroleum, natural gas, water supply and drainage pipework.
