What is the difference between a welded steel pipe and a welded spiral steel pipe
Welded steel pipe refers to a steel pipe with seams on the surface, which is made by bending and deforming steel strips or steel plates into circular, square, and other shapes and then welding them. The blank used for welded steel pipes is a steel plate or strip. Since the 1930s, with the rapid d...Read more -
Comparison of the advantages and disadvantages of spiral steel pipe and straight steel pipe welds
The weld seam of spiral steel pipe is longer than that of straight seam steel pipe. If the pipe length is L, the weld seam length is L/cos(θ). Most of the defects in steel pipes are concentrated in the welds and heat-affected zones. Long welds mean a high probability of defects. This is the main ...Read more -
