Home piping The pressure is Water pipe installation The test items to be carried out from time to time are to judge whether the water pipe connection is firm or not, and whether there will be water leakage; Of course, there are also many points to be noted during the pressure test, such as: try not to retain air in the water pipe during the test to avoid affecting the accuracy of the pressure test Pipe manufacturer I will give you a detailed introduction.

I Domestic water pipe Standard of suppression

1. The pressure standard of domestic water pipes is generally 9-10 kg water pressure, and the pressure holding time is generally 30 minutes. The pressure test is one of the common methods to judge whether the water pipe connection is reliable.

2. During the pressure test, check the connectors and inner wire connectors one by one, and the plug shall not have water seepage, otherwise it will directly affect the gauge needle of the pressure tester.

3. The method of use is to connect the cold and hot water pipes with hoses. The cold and hot water pipes form a circle and form a pipe. The pressure tester can be connected to any water outlet.

4. Pressure test can be carried out only after all water pipe channels are welded. Before pressure measurement, all plugs shall be plugged and the valve of water inlet main pipe shall be closed.

5. During pressure measurement, shake the pressure bar of the jack until the pointer of the pressure gauge points to 0. 9－1。 0 or so, that is to say, the current pressure is three times of the normal water pressure, and the pressure value is maintained for a period of time.

6. The pressure measurement time of different water pipes is different. The welding time of PPR, aluminum plastic PPR, steel plastic PPR and other pipes is 30 minutes.

7. The aluminum plastic pipe is the kind of copper joint, and its time is 4 hours.

8. Galvanized pipe takes 4 hours and half a working day.
