Comparison between plastic-coated steel pipes and 3PE anti-corrosion steel pipes
Plastic-coated pipes, also known as plastic-coated steel pipes, steel-plastic composite pipes, and plastic-coated composite steel pipes, are based on steel pipes and use PE (modified polyethylene) for hot dip molding or EP (epoxy resin) as the main anti-corrosion raw material. It is a steel-plast...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
