51 steel pipe network to provide: Seamless steel pipe under pressure calculation formula One: to know the thickness of the outer diameter of seamless steel pipe wall thickness to calculate the method to withstand pressure (the different tensile strength of different steel pipe materials) 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<Pipe pressure P<17.5 Coefficient S=6 Pressure P>17.5 Factor S=4 (Information Sources)
