Large straight seam welded pipe refers to a straight seam welded steel pipe with a diameter of 325 millimeters or more and a large wall thickness.
Due to these advantages, color coated coils are widely used across various sectors, including construction, home appliances, and automotive manufacturing, and have become essential high-performance materials in modern industry.
Spiral pipe, also known as spiral steel pipe or spiral welded pipe, is made by rolling low-carbon structural steel or low-alloy structural steel strip into a pipe blank at a certain angle of the spiral line (called forming angle), and then welding the pipe seam together. It can produce large-diameter steel pipes with narrower strip steel.
