Pipes Hydro-Testing
Hydrostatic testing of pressure piping is a mandatory activity before the finalization of any new or modified piping system. It is the final check of the mechanical integrity of the whole system and should be followed religiously as after this activity the piping system has to be commissioned.
This test is carried out at a pressure 1.5 times higher than the design pressure of a system regardless of the service conditions of a piping system. This article discusses some of the major requirements of hydrostatic testing of pressure piping as per ASME B31.3 for process piping and specifically provides guidelines on some issues not directly addressed in the code.
