The pressure calculation formula method of seamless steel pipe

A: in order to know outside diameter specifications of wall thickness and the calculation methods of stress (tensile strength of steel tubes with different materials and different)


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


Two: to know the diameter and pressure for wall thickness calculation method:


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


Three: the representation method of steel pipe pressure coefficient:


The pressure coefficient of P<7Mpa S=8


7< steel pipe pressure coefficient of P<17.5 S=6


The pressure coefficient of P>17.5 S=4
