Stress calc for hydrotesting?
A simple hoop stress calc based on code should be sufficient. This is to ensure that the design pressure selected for the piping class is such that hoop stress during hydrotest pressure (typically 1.5 times design pressure) does not exceed code limits.

do you guys really perform a stress calc for every piping system requiring hydro at the plant? we dont. and we got several dozens of different piping class from hdpe to duplex to c-moly. but every single piping installed are fully documented. i meant every single spool installed - doesnt matter if its utility or process piping.

makes repair, alteration or mods later on a breeze.
