The welding seam of the spiral steel pipe is longer than that of the straight seam steel pipe. If the pipe length is L, the welding seam length is L/cos(θ). The vast majority of steel pipe defects are concentrated in the weld and heat-affected zone. The long weld means that the probability of defect

①Advantages of material propertiesAs the name suggests, the thin-walled stainless steel water pipe is made of stainless steel. The strength of stainless steel is 3 times that of copper pipe and 8 to 10 times that of PPR pipe. It can withstand the impact of high-speed water flow at 30 meters per seco

In the use of straight seam steel pipes in daily projects, the safe placement of straight seam steel pipes in projects is particularly important. How to properly place straight seam steel pipes?1. When the straight seam steel pipe is hoisted, the wire rope is not allowed to be pulled diagonally to p
