Welded steel pipe refers to a steel pipe with seams on the surface that is welded by bending and deforming a steel strip or steel plate into a circular, square or other shape. The blanks used for welded steel pipes are steel sheets or strips. Since the 1930s, with the rapid development of strip rolling production and the advancement of welding and inspection technology, the quality of welds has been continuously improved, the varieties and specifications of welded steel pipes have been increasing, and they have replaced seamless steel pipes in more and more fields. Steel Pipe. Welded steel pipes have lower cost and higher production efficiency than seamless steel pipes.
3PE anti-corrosion steel pipe refers to an external anti-corrosion steel pipe with a three-layer structure polyethylene coating, which is a kind of anti-corrosion pipe often used in the oil pipeline industry. 3PE anti-corrosion steel pipe category Precision seamless steel pipe is a high-precision steel pipe that has been cold-drawn or cold-rolled or processed. The full name is cold-drawn or cold-rolled precision seamless steel pipe.
The production process of the spiral steel pipe is to extrude it under the normal temperature environment, use the strip steel coil as the raw material, and use the automatic double-wire double-sided submerged arc welding process to weld and process the spiral seam steel pipe.
