How is the pressure of q345b seamless steel pipe calculated

q345b seamless steel pipe is an important model and type of seamless steel pipe, generally q345b seamless steel pipe has a certain pressure, which is also where it is used in the process. The pressure is calculated in the process of engineering calculations and engineering design, so what is the method of calculating the pressure of q345b seamless steel pipe? We and q345b seamless steel pipe to understand in detail how the common pressure is calculated it: one: known q345b seamless steel pipe.

  A: known q345b seamless steel pipe outside diameter and pressure to find the wall thickness calculation method

  Pressure = 1Mpa

  Outer diameter = 168mm

  Coefficient = 8

  Material tensile strength = 400Mpa

  Wall thickness = (pressure * outside diameter * coefficient) / (2 * steel pipe material tensile strength) = 1.68mm

  Second: known q345b seamless steel pipe outside diameter specifications wall thickness to seek to withstand the pressure calculation method

  Wall thickness = 2mm

  Tube outer diameter = 21mm

  Coefficient = 8

  Material tensile strength = 400Mpa

  Pressure = (wall thickness * 2 * steel pipe material tensile strength) / (outside diameter * coefficient) = 9.52Mpa

  The above is the main calculation method of common q345b seamless steel pipe pressure and the main calculation process for your reference.
