HYDROSTATIC TESTING PROCEDURE AND TYPES

16/04/2021  Hydrostatic testing is a type of pressure test that works by completely filling the component with water, removing the air contained within the unit, and pressurizing the system up to 1.5 times the design pressure limit the of the unit. The pressure is then held for a specific amount of time to visually inspect the system for leaks. Visual inspection can be enhanced by applying either

Safe pressure testing of pipes - WorkSafe

Hydrostatic pressure testing only requires a relatively small amount of liquid to develop a high pressure. It is therefore only able to release a small amount of energy in a pipe or joint failure. Use hand-operated testers. When testing pipes for system integrity and locating leaks, hand-operated testers should be used. This is because hand-operated testers have a lower compression rate, which ...
