316l Stainless Steel Pipe Outside Diameter

316l Stainless Steel Pipe Outside Diameter

What is the pressure of 316L stainless steel pipe?

1, to know the outer diameter specification wall thickness can withstand the pressure calculation method (different steel pipe materials tensile strength is different)
Pressure =(wall thickness *2* steel pipe material tensile strength)/(outer diameter * coefficient)
2, to know the outer diameter and pressure to calculate the wall thickness:
Wall thickness =(pressure * outer diameter * coefficient)/(2* tensile strength of steel pipe material)
3, steel pipe pressure coefficient expression method:
Pressure P<7Mpa coefficient S=8
7< steel pipe pressure P<17.5 coefficient S=6
Pressure P>17.5 coefficient S=4.
Tensile strength (Mpa)520
