    What are the specified values of steel pipe wall thickness

    As an important building material, steel pipe is widely used in various fields. The wall thickness of the steel pipe is one of its important parameters, which is directly related to the strength, bearing capacity, and service life of the steel pipe. So, what are the specified values for the wall ...

  • The difference between HFW steel pipe and ERW steel pipe

    The difference between HFW steel pipe and ERW steel pipe

    The difference between ERW (straight seam electric resistance welded) steel pipe and HFW (high frequency welded) steel pipe is mainly the principle. As the name implies, resistance welding is a method in which pressure is applied through electrodes after the weldment is combined, and the resistan...
