[MW:25407] Re: Regarding design and working pressure

MAWP (API570)
The maximum internal pressure permitted in the piping system for continued operation at the most severe condition of coincident internal or external pressure and temperature (minimum or maximum) expected during service. It is the same as the design pressure, as defined in ASME B31.3 and other code sections, and is subject to the same rules relating to allowances for variations of pressure or temperature or both. If the piping system is being rerated, the new MAWP shall be the rerated MAWP

Dear sir / experts,

As we know that, hydrotest pressure = 1.5 design pressure.

Then, in the same mathematical way, what is relation between design pressure and working pressure.

Pls help.

Regards

Prasad Rode
