Do you need to do water pipe suppression test for waterway reconstruction? Introduction of pressure test steps of water pipes

In the process of family waterway reconstruction, many friends ignored the water pipe suppression test. If you have friends who are leaking at home, think about whether you did a water pipe suppression test at the beginning. Waterway reconstruction requires water pipe suppression test, which is generally handed over to hydropower workers. Here are some steps of water pipe suppression test, hoping to help you.

First, the water pipe pressure test steps

1. At the beginning of the water pipe pressure test, connect the hot and cold water pipes with hoses. This hot and cold water will form a circle and become a pipe. The pressure tester can be connected to any water outlet. At this time, the pressure pointer is 0 pressure.

2. Water pipe pressure test can only be carried out after all water pipe passages are welded. Before pressure measurement, all plugs should be plugged and the inlet main valve should be closed.

3. During the water pipe pressure test, shake the pressure rod of the jack until the pointer of the pressure gauge points to about 0.9- 1.0, that is, the current pressure is three times that of the normal water pressure.

4. Keep this pressure value for a certain time, and the pressure measuring time of different water pipes is different. PPR, aluminum-plastic PPR, steel-plastic PPR and other welded pipes. It's 30 minutes (more than, not less than). Aluminum-plastic pipe is the kind of copper joint, and the time is 4 hours (half a working day). Galvanized pipes also take 4 hours.

Second, the water pipe pressure test results check

During the water pipe pressure test, check the connectors and internal wire connectors one by one. There must be no water seepage in the plug. Some people say that the plug leaks water, which is a lie. The water seepage of the plug directly affects the pointer of the pressure tester. Who knows if the needle will keep falling? The pointer of the pressure tester does not drop at all or the drop range is less than 0. 1 within the specified time, indicating that the water pipeline is good and the pressure tester is in normal working condition.

The above is the waterway reconstruction. Do you need to do a water pipe suppression test? Introduction of water pipe pressure test steps.
