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 tube blank according to a certain spiral angle (called forming angle), and then welding the tube seam. It can produce large diameter steel pipe from narrow strip steel.

standard

Commonly used standards for spiral pipes are generally divided into: SY/T5037-20 18 (ministerial standard, also known as spiral seam submerged arc welded steel pipes for general fluid transportation pipelines), GB/T971.1-1997 (.

classify

Spiral submerged arc welding pipe for pressurized fluid transportation is mainly used for pipelines transporting oil and natural gas. Steel pipe has strong bearing capacity and good plasticity, which is convenient for welding and processing. Spiral submerged arc welded steel pipes for general low-pressure fluid transportation are manufactured by double-sided automatic submerged arc welding or single-sided welding, and are used for conveying general low-pressure fluids such as water, gas, air and steam.
