STRAIGHT SEAM STEEL PIPE AND SPIRAL STEEL PIPE WHAT DIFFERENCE DOES IT MAKE?

The difference between straight seam steel pipe and spiral steel pipe:
1. From the processing perspective: straight seam steel pipe is bent into a tubular certain width and is welded equipment is relatively simple, productivity is higher. Spiral steel pipe is made of a certain width around the steel tube and is welded equipment is relatively complex, and because the weld than the straight seam steel pipes much longer, so a number of relatively low productivity.
2, from the strength point of view: straight seam steel pipe after welding, the internal stress distribution along the weld, and the internal stress axially and radially spiral welded steel pipe after the uniform distribution can be better partially offset the pressure. So the pressure capacity, spiral pipe stronger.
