An alternative leak test is only permitted by ASME B31.3 when: Exposure of the piping to water via a hydrostatic test would damage the linings or internal insulation, or contaminate a process that would be hazardous, corrosive, or inoperative in the presence of moisture; and (3) Except for natural gas, nonflammable. The volume of equipment under test should be kept as small is greater than the test pressure. (a) Each segment of a service line (other than plastic) must be leak tested in accordance with this section before being placed in service. 2- Hydrostatic pressure test, according to the view of the supervisor and the project consultant, is better to calculate based on the pressure (less than the nominal pressure . Hydrostatic testing: Relieves pressure and disposes of test fluid as described in Pressure Test Plan and returns relief devices to normal configuration . p Test pressure (bar). For RTR laminated and filament wound pipe, the test pressure should be three times the manufacturers allowable pressure rating. Over the years, I have conducted hundreds of pressure tests, and I have collected a lot of documentation about this non-destructive test method. A hydrostatic test is a pressure test method that uses a liquid as a fluid medium in order to increase the pressure of a piping system to the desired target final test pressure. Position the balance arm on the knife edges and check that the arm swings freely. If an inspection is required within the hold period, then pressure should be reduced to 80% of the test figure. The most common liquid used for conducting a hydrostatic pressure test is water; however, other liquids can and have been used for hydrostatic pressure tests. All equipment, plant, and devices used for pressure and leak testing are properly rated, adequately calibrated, maintained, and checked.
