Pipeline Hydro test pressure calculation

[JIJILAL K M]

Dear Experts,

For the pipeline hydro test calculations,what is the pressure in bar required to produce hoop stress equal to 4341.45 kg/cm2? 

Best Regards,

Check the design pressure first based on which the hydro test pressure has been set from your end .  Hydrotest need not be designed  as per code.

did not understand the term volume pressure.hydro could be 1.5 times the design pressure. check first what is the design code being used.

I understand your question well, but to be able to do this calculation you need some data to work with the Hoop Stress formula: It is the wall thickness of the tube to which you will test, the Outside Diameter of the line of pipe to be tested, the Yield of the material from which the tube is made, which you can find in ASME Section II Part D.
Cheers!
