How normal is the water pipe pressure drop? How to treat water pipe leakage when it is pressed? How much is the water pipe pressure test?

When doing water and electricity decoration, it is necessary to press and install water pipes. The purpose of pressing is to test whether the water pipe and pipeline are firmly connected. During the pressure test, check that there is no water seepage at the joint and plug, otherwise it will affect the pointer of the pressure test gauge. Most owners may not know much about the suppression. Next, let's take a look at how normal the water pipe pressure drop is, how to treat the water pipe leakage, and how much the water pipe pressure test will cost. I hope it will help everyone.

1. How normal is the water pipe pressure drop?

1, the normal pressure drop of the water pipe is 0.8, and it should not be lower than 0.75 after half an hour. During the hydraulic test, the pleural pressure is the working pressure of the pipeline, and the test pressure should not be less than 0.80MPa. When the working force of the pipeline is less than this value, the hydraulic test pressure should be 0.8MPa, and the pneumatic test cannot be used instead of the hydraulic test.

2. When the water supply pipe is press-fitted, it should be noted that it can only be carried out 24 hours after the water supply pipe is installed. Generally, the pressure will be 8 kg for about half an hour, so as to ensure the safety and accuracy of the water supply pipe pressure.

3. The water pipe pressure test is generally carried out under the condition of 1.5 times the water pressure. If there is no water leakage during the test, it means that there is no problem with the water pipe and it can be used normally.

4. In the process of pressing, don't press it too fast, otherwise it will easily damage the watch cover. Once damaged, the instrument cover must be replaced.

Second, how to see the water pipe leaking when it is pressed?

1. When the water supply pipe is pressed, check the joints and internal wire joints one by one for water leakage. If there is water leakage, it will be directly reflected on the pointer of the pressure tester, and the pressure value will drop rapidly. If there is water leakage, it should be remedied in time.

2. When the water supply pipe is pressed, many construction workers will speed up the pressing in order to catch up with the time. In fact, it is impossible to correctly measure whether the water supply pipe is qualified by speeding up the suppression, so it must be controlled in time.

3. Within the specified pressing time, the pointer of the presser does not drop significantly or the drop range is less than 0. 1MPa, indicating that the water pipe is in good condition and the presser is in normal working condition.

Third, how much is the water pipe suppression test?

1. If you want to suppress water pipes, you can find a residential property. Some residential properties are suppressed for the owners free of charge, of course, it is usually the first time.

If you hire someone from outside to suppress the water pipe, you will have to pay. The charging standard in each region is different, depending on the specific situation, it is generally around 400 yuan.

3. The purpose of water pipe crimping is to check whether the quality of pipes and interfaces is qualified. You can use the water pipe safely only if the water pipe is qualified by pressure welding, so don't omit this step to save trouble, otherwise the water pipe is likely to leak.

The above is about how normal the water pipe pressure is, how to look at the water pipe leakage, and how much it costs to test the water pipe pressure. Thank you for reading. If you want to know more about water pipe pressure, please continue to pay attention to hunting nets.
