Calculation method of pressure resistance of seamless steel pipe

One: Knowing the calculation method of the pressure and the wall thickness of the seamless steel pipe outer diameter specifications (the tensile strength of different materials of steel pipes is different)

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

2: Knowing the calculation method of wall thickness of seamless steel pipe and seamless steel pipe under pressure:

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

3: Representation method of steel pipe pressure coefficient:

Pressure P <7Mpa
Coefficient S = 8

7 <steel tube pressure P <17.5
Coefficient S = 6

Pressure P> 17.5 Coefficient S = 4
