how to fix the desing pressure of the pipe? Is there any exact formula to calculate the design pressure of the pipes. kindly explain.

[samayaraj]

Design pressure of pipe is generally taken as centrifugal pump shutoff head or the safety valve set pressure.

Are you asking about selection or calculation of the design pressure/MAWP? If you are interested in calculation, look at the piping code your project adheres to - usually based on ASME B31.3 if process piping is in question.

krishnamurthy,

 

As zauberberg mentioned you should refer to relevant piping code; for example in ASME B31.3 the design pressure, in brief, is a pressure value which with coincident temperature will lead to highest pipe thickness...

from my experience,

 

generally, process design pressure is maximum possible operating pressure + 1 barg OR maximum possible operating pressure x 110%.
