Standard Classification Spiral seam submerged arc welded steel pipes for pressurized fluid transportation are mainly used in pipelines for transporting oil and natural gas. Spiral seam high-frequency welded steel pipes for pressurized fluid transportation are welded by high-frequency lap welding and are used for pressurized fluid transportation. Spiral seam high-frequency welded steel pipes. The steel pipes have strong pressure-bearing capacity and good plasticity. They are easy to weld and process. Spiral seam submerged arc welded steel pipes are generally used for low-pressure fluid transportation. They are made by double-sided automatic submerged arc welding or single-sided welding. Submerged arc welded steel pipes for general low-pressure fluid transportation such as water, gas, air and steam
Common standards for spiral steel pipes are generally divided into / (industry standards, also called spiral seam submerged arc welded steel pipes for ordinary fluid transportation pipes), / (National standard, also called oil and gas industry transportation steel pipe delivery technical conditions, first part graded steel pipe (strictly demanding graded steel pipe and graded steel pipe)), (American Petroleum Institute standard, also called pipeline steel pipe, which is divided into two levels: and ), / (Spiral seam submerged arc welded steel pipe for piles) Spiral seam submerged arc welded steel pipe for pressure fluid transportation () is made of hot-rolled steel strip coils as pipe blanks, which are spirally formed at regular temperatures and welded by double-sided submerged arc welding. Spiral seam steel pipes used for transporting pressurized fluids. Steel pipes have strong pressure-bearing capacity and good welding performance. They have undergone various rigorous scientific inspections and tests and are safe and reliable to use. The steel pipe has a large diameter, high transportation efficiency, and can save investment in laying pipelines. Mainly used for pipelines transporting oil and natural gas.
