Large Diameter Spiral Steel Pipe Q235B For Fluid Transmission

Q235B spiral pipe is a commonly used raw material in spiral pipes.It is a spiral seam steel pipe welded with strip steel coil as the raw material and active double wire double-sided submerged arc welding. The main technical characteristics of the spiral steel pipe: During the forming process, the steel plate is uniformly deformed, the residual stress is small, and the surface does not scratch. Can meet the user’s more requirements in the spiral steel pipe standard.
