1. The calculation method of the ability to withstand the pressure based on the outer diameter and wall thickness of the seamless steel pipe (the tensile strength of different materials of the steel pipe is different)

Pressure = (wall thickness * 2 * tensile strength of steel pipe material) / (outer diameter * coefficient)

2. Calculate the wall thickness by knowing the outer diameter and pressure of the seamless steel pipe:

Wall thickness = (pressure * outer diameter * coefficient) / (2 * tensile strength of steel pipe material)

3. The method of expressing the pressure coefficient of the steel pipe:

Pressure P<7Mpa Coefficient S=8

7<Pipe pressure P<17.5 Coefficient S=6

Pressure P>17.5 Coefficient S=4
