Easier to use than manual pumps, these use electricity to quickly pump water through your system so you can test for leaks. They are also known as hydrostatic test pumps. They are portable so they can be lifted and moved to any location.. Style B is protected by a metal cage with rubber feet; it includes a 10-ft. hose for high-pressure applications. Hydrostatic Testing of Welded Stainless Steel FabricationsAPI 570:Piping & Inspection Code, American Petroleum Institute. Piping fabricated of or having components of 300 series stainless steel should be hydrotested with a solution made up of potable water (see note) or steam condensate.After testing is completed, the piping should be thoroughly drained (all high-point vents should be opened during draining), air blown, or otherwise dried.
It is the final check of 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. Non Destructive Testing - Pressure Testing is a non Furthermore, the test pressure must never exceed a pressure that would cause yielding, or the maximum allowable test pressure of some component exposed to the test. In the case of ASME B31, section 137.1.4, and the Boiler and Pressure Vessel Codes, the maximum test pressure must not exceed 90 percent of yield for any component exposed to the test.
