It is made by rolling low-carbon carbon structural steel or
low-alloy structural steel strip according to a certain spiral
angle (called forming angle) into a tube blank, and then welding
the tube seam together. It can be made with a narrower Strip steel
produces large diameter steel pipes. Its specifications are
expressed by outer diameter * wall thickness, and the welded pipe
shall be ensured that the hydraulic test, the tensile strength of
the weld and the cold bending performance must meet the
requirements.
The production of spiral welded steel pipes can reflect the
advantages of high quality and high efficiency. The production
capacity of one spiral welded pipe unit is equivalent to 5-8 sets
of straight seam welded pipe equipment. How to make multiple pipe
coiling equipment production lines meet the same production
standard, that is, produce according to a unified production
process specification and quality assurance system to meet welding
quality Requirements and piping manufacturing grades will be an
arduous task.
