For hydrostatic testing with water, the testing pressure should be 1.5 times the maximum operating pressure
For hydraulic pressure testing, the testing pressure should be 1.5 times the maximum operating pressure
The operating pressure isn’t relevant; it’s the design pressure that matters. For thermal pipelines, the temperature coefficient also needs to be taken into account
For hydraulic pressure testing, the testing pressure should be 1.5 times the maximum operating pressure
1.5 The hydrostatic test of indoor water supply pipes must meet the design requirements. When not specified in the design, the test pressure for water supply pipe systems made of various materials is 1.5 times the operating pressure, but it must not be less than 0.6 MPa. Testing method: For metal and composite pipe water supply systems, the system is held at the test pressure for 10 minutes; the pressure drop should not exceed 0.02 MPa. After that, the pressure is reduced to the operating level for inspection, during which no leaks should occur ； The plastic pipe water supply system should be held at the test pressure for 1 hour, with a pressure drop of no more than 0.05 MPa; thereafter, it should be held at 1.15 times the operating pressure for 2 hours, again with a pressure drop of no more than 0.03 MPa. At the same time, it is necessary to check that there are no leaks at any connections.
