Test Knowledge Of PPR Pipe Fitting

- Jan 09, 2018-

PPR pipe fittings manufacturer said that the PPR pipe fitting must be tested for hydraulic pressure after installation. If it is a dark pipe, it should be able to conceal the pipe after the water pressure test.

The step of the pipe hydraulic test is to stop the end of the pressure test tube, slowly fill the water, and discharge the air in the pipe at the same time. Then use the hand pressure pump to increase the pressure slowly, and the lift time should not be less than 10 minutes; After the pressure is increased to the specified test pressure, the pressure is stopped to observe whether there is leakage in the joints. After 1 hour of stabilization, the pressure value will be added to the test pressure value. If the pressure drop is not more than 0.05mpa within 15 minutes, it will be qualified.

It is important to note that must be 24 hours later, at the end of the heat pipe system installation for water pressure test, and test of pipe should be fixed effective measures, the joint part of test pipe shall be bare.
