1000mm SSAW steel pipe large diameter oil and gas carbon steel ERW spiral welded pipe tube
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.
