What are the inspection rules for the Plastic pipes system performance tester?
The
Plastic pipes system performance tester shall comply with the following requirements:
1. The hydraulic test should be carried out after the completion of the interface for more than 24 hours. The total length of the pipeline for a hydraulic test should not be greater than 500 m.
2. Before the hydraulic test, the pipe should be fixed firmly and reliably, the joint should be exposed, and the end of the branch pipe should not be connected with the water fittings of the sanitary appliances except the valves.
3. Manual
Plastic pipes system performance tester The pressure gauge for pressure measurement should be installed at the bottom of the pipeline system at the lowest point (the pressure value of geometric height difference should be converted when not at the lowest point). The pressure gauge accuracy of the performance tester for plastic pipeline system should be 0.01 Mpa.
4. After the pipeline is filled with water, the air in the pipeline is discharged, the exhaust outlets are blocked, and the water tightness is checked.
5. Slow boost, boost time should not be less than 10 minutes, rise to the prescribed test pressure (within 30 minutes, allowed two times to test pressure), regulate pressure for 1 hour, test should be no leakage, test pressure drop should not exceed 0.06 Mpa;
6. When the design working pressure is 1.15 times, the pressure drop should not exceed 0.03 Mpa for 2 hours. At the same time, no leakage is found and the hydraulic test is qualified.
