Pressing Steps Of Ppr Tube

1 The test pressure is 1.5 times the working pressure of the pipeline system, but not less than 0.6Mpa

2 For the PP-R piping system, the water pipe test is generally required to be carried out 24 hours after the installation of the pipe connection.

3 Before the pressure test of the water pipe, safe and effective fixing and protection measures should be taken for the pipe, but the joints are exposed.

4 Hydrostatic test steps

(1) Block the end of the pressure test pipeline, slowly inject water, and remove the gas in the pipeline at the same time. (2) After filling with water, check the water tightness. (4) Raise the test pressure to the test pressure, stop the pressurization, stabilize the pressure for 1 hour, and observe whether there is water leakage at the joint (5) stabilize the pressure for one hour, and make up the pressure to the test pressure value. qualified
