What is stainless steel pipe allowable working pressure?

Stainless steel pipes are made up of different materials with different compositions. All of the material grades have yield and tensile strength values. The yield strength is what the material could withstand before changing shape permanently while the tensile strength is at which the pipe will rip apart when pulled from opposite directions.

Similar to the yield and tensile strength, there are working pressure and bursting pressures for pipes. The pipes have to operate under various temperatures and pressures. The maximum allowable working pressure indicates the pressure at which the pipe can operate without starting to change. The bursting pressure is at which pressure the pipe will begin to burst. There are different values of allowable working pressures for different materials, diameters, wall thicknesses, and schedules. For example, the standard wrought steel pipes at schedule 40 would have 1080PSI of allowable working pressure for ¾ inches diameter.

With the increment of diameter, the allowable working pressure decreases. The 1-inch pipes have 1010PSI and the 1 ¼ inch pipes have 840PSI. The working pressure is calculated with Barlow’s formula. The yield strength of the pipe is multiplied by the design factor of the pipe to derive the allowable working pressure.

    Ans: Seamless steel pipe cost is almost 40-50% higher compared to the welded pipes due to manufacturing process & raw material, click here to view the updated Stainless Steel Seamless Pipe Price List.
  • What is the maximum pressure of SCH40 Seamless Pipes?
    Ans: Pressure rating depends upon sizes, wall thickness & temperature. For example:
    1" SCH40 WT 0.133, 100°F = 2205 PSi
    10" SCH40 WT 0.365, 100°F = 699 Psi
  • Why in high pressure applications SS Seamless Pipe is prefered?
    Ans: Welded pipe can be cracked on high pressure while Seamless Pipes can withstand extremely high pressure without cracking. So seamless pipe can take 20% higher pressure compared to welded.
  • What is the weight difference between Welded and Seamless Pipe?
    Ans: The welded pipe is 30% heavier compared to seamless pipe because of welding of HR coil, don't forget.
