Seamless steel pipes are widely used.1. General-purpose seamless steel pipes are rolled from ordinary carbon structural steel, low-alloy structural steel, or alloy structural steel, and have the largest output. They are mainly used as pipelines or structural parts for conveying fluids.2. According t

Comparison of advantages and disadvantages of welded seams between spiral steel pipes and straight seam steel pipesThe 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). The vast majority of steel pipe de

How to solve the "goose head bend" phenomenon of spiral steel pipeIf the large-diameter spiral steel pipe is processed to a certain length, bending will exist, and it is a phenomenon and situation that is often encountered in steel pipes. Large-diameter spiral steel pipe is due to unevenness along t

Points for Attention in Welding Technology of Longitudinal Steel Pipes and Diameter Expansion TechnologyLongitudinally welded pipe diameter expansion is a pressure processing technology that uses hydraulic or mechanical means to apply force from the inner wall of the steel pipe to expand and expand
