Comparison of advantages and disadvantages of spiral steel pipe and straight seam steel pipe weld

Keywords :Comparison of advantages and disadvantages of spiral steel pipe and straight seam steel pipe weld         Update : 2023-04-07        View(s) : 70

The weld seam of the spiral steel pipe is longer than that of the straight seam steel pipe. If the pipe length is L, the weld seam length is L/cos(θ). However, most of the defects of steel pipes are concentrated in the weld seam and the heat-affected zone. The long weld seam means that the proba...
