Spiral Structural Steel Pipe

Spiral Structural Steel Pipe

The spiral structural steel pipe is jointed by welding, but the welding seam is spiral rather than straight. The spiral welding seam type steel tube has high crack resistance property and few defects during the welding process. It can be particularly used as pipeline with high durability requirement such as road construction casing pipe to lower the maintenance cost. Thus, it’s often applied to achieve road construction, piling and trench building.
