  1. the spiral steel pipe for low pressure fluid transfer is also called the general welded spiral steel pipe pipe, commonly known as the black pipe. It is a spiral steel pipe used for conveying water, gas, air, oil, heating steam and other general low pressure fluids and other purposes.

  2. the straight seam electric welded spiral steel pipe is a steel pipe longitudinally parallel to the pipe. They are usually divided into API 5L Gr B Sch 40 Welded Spiral Steel Pipe, welded thin-walled tube, transformer cooling oil pipe and so on.

  3. Spiral steel pipe seam submerged arc welded steel pipe for pressurized fluid conveying is a spiral seam steel pipe for pressurized fluid conveying, which is formed by hot rolled steel strip coil and welded by double-sided submerged arc welding. The steel pipe has strong bearing capacity and good weldability. It is safe and reliable to use after various strict scientific tests and tests. The diameter of the spiral steel pipe is large, the transportation efficiency is high, and investment in laying pipelines is saved. It is mainly used for transporting oil and natural gas pipelines.

  4. The welded spiral steel pipe for pressurized fluid conveying is a spiral seam high-frequency welded spiral steel pipe for pressurized fluid conveying, which is made of hot-rolled steel strip coil and often formed by warm spiral forming and welded by high-frequency overlap welding method. The steel pipe has strong bearing capacity, good plasticity, and is easy to be welded and processed. Through various strict and scientific tests and tests, it is safe and reliable to use, large diameter of steel pipe, high conveying efficiency, and can save the investment of laying pipelines. It is mainly used for laying pipelines for transporting oil and natural gas.
