Advantages And Disadvantages Of Spiral Submerged Arc Welded Carbon Steel Pipe

 Main advantages and disadvantages
advantage
Advantages of large diameter: narrow strip steel can be used to produce large diameter pipes with low cost.
Higher strength: Spiral welds bear better stress, and the overall strength is better than straight seam welded pipes.
Flexible and changeable: the diameter can be changed by changing the molding angle, suitable for small batches and multiple varieties.
Accurate dimensions: small ovality (≤0.5% of pipe diameter).
shortcoming
The weld seam is longer: 3 to 5 times that of straight seam pipes, and the inspection cost is high.
Limited pressure bearing: lower than seamless steel pipe, mostly used for medium and low pressure.
Large investment in equipment: The production line is complex and the investment is high.
