2200 ton hydraulic press and microcomputer automatic recording system: inspect the pressure bearing quality of each large diameter steel pipe.

Spiral welded pipe

Spiral pipes, also known as spiral steel pipes or spiral welded pipes, are made by rolling low-carbon structural steel or low alloy structural steel strips at a certain helix angle (called forming angle) into pipe blanks, and then welding the pipe seams together. It can produce large-diameter steel pipes from narrower strip steel.
