Cold Dipped Galvanized Round Steel Pipe Galvanised Tube Spiral Seam Steel Pipe


The ASTM A269 specification covers nominal-wall-thickness, seamless and welded austenitic steel tubing for general corrosion-resisting and low- or high-temperature service. Upon completion, all material shall:

  • shall be furnished in the heat-treated condition.
  • conform to the chemical composition requirements.
  • different mechanical test requirements that includes, flaring test, flange test, hardness test, and reverse flattening test are presented.
  • shall be subjected to the non-destructive electric test or the hydrostatic test

Product Description


  1. The high-frequency welding (HFW) is mainly used in ordinary or thin wall steel pipe. It includes contact welding and induction welding. Direct current welding is generally used for small-caliber steel tubes.
  2. In general, HFW is one of ERW production methods, it adopts the high-frequency welding process. So, the ERW steel pipe includes the HFW steel pipe.
  3. ERW steel pipe application and usage
  4. ERW steel pipe used for transporting gas and liquid objects such as oil and gas could meet the low and high-pressure requirement. In recent years, with the development of ERW technology, more and more ERW steel pipes used in the oil and gas fields, the automobile industry and so on.
  5. Advantages of ERW pipe and HFW pipe
  6. ERW pipes’ advantage is high efficiency, low cost, material saving, easy automation.
