Formula method of pressure calculation for seamless steel tube

One: To know seamless steel tube outside diameter specification wall thickness to be able to withstand pressure calculation method (steel pipe different tensile strength of different materials)

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

　　Second: To know seamless pipe tube outside diameter and pressure to calculate the wall thickness calculation method:

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

　　Three: the steel tube pressure coefficient representation method: Pressure p<7Mpa 系数s="8"></7Mpa><><17.5 系数s="6" 　　压力p="">17.5 factor s=4</17.5>
