A: Knowing the thickness of the outer diameter of the seamless steel tube seamless pipe thickness calculation method to calculate the withstand pressure (the tensile strength of different materials of the steel pipe is different)
Pressure = (wall thickness * 2 * tensile strength of steel pipe) / (outer diameter * coefficient)
II: Knowing the outer diameter of the seamless steel tube and the pressure for the wall thickness calculation method:
Wall thickness = (pressure * diameter * coefficient) / (2 * tensile strength of steel pipe material)
Three: Steel pipe pressure coefficient representation method:
Pressure P<7Mpa Factor S=8
7<Steel Pressure P<17.5 Factor S=6
Pressure P>17.5 Coefficient S=4
