Plumbing is an essential part of every home life, and although it is said that the plumbing is a hidden part, water leakage from the plumbing interface often happens. Since it is a hidden part, what is the method of water pipe interface leak detection fee. The problem of water pipe interface leaks is now more and more common, many reasons can lead to the phenomenon of water pipe interface leaks
1、Collection of pipeline information
Collect the need to test the pipeline drawing information and water consumption information, the enterprise arranged familiar with the location of the pipeline technical personnel on site to point out the plane location of the pipeline, burial depth, material, diameter and other related information.
2、Regional pipeline network environment survey
Fully understand the site situation, for the next leak detection work of construction arrangements, method selection and other preparations, it includes the pipe network environment survey, subsidiary equipment survey, water use survey and drainage survey, etc.
3、Leakage detailed investigation
In the work area, daytime fire hydrants, valves, water meters and open pipes in the area for 100% direct listening to listen to the sound waves propagated from the leak point to the pipeline structures to find water leakage anomalies. Detailed records are made after the discovery of abnormalities.
4、Sound and sound detection
In the investigation area above the pipeline, with PQWT pipe leak detector connected to the host, headphones, sensors. Turn on the switch, put on the headphones, place the sensor on the road above the pipeline, place it step by step according to the length of the pace, step by step listening, the closer to the leak, the stronger the signal, the farther away from the leak the weaker the signal, by comparing the signal strength between different points to achieve the purpose of detecting leaks. Therefore, we use the instrument, a single point to listen to the leak signal is not meaningful, to multi-point repeatedly compared, compared with the sound vibration of the larger place is the leak, of course, we have to consider many other additional factors, such as the direction of the leak breakage mouth, because the pipe is round, if the side of the leak, may be larger points instead in the side of the road above the pipe, rather than being the pipe In addition, tee, bend, water pressure, burial depth, burial layer, etc. will all have an impact, and these should be taken into account when testing.
The operation is carried out at a time when the water consumption is relatively stable and the surrounding environment is relatively quiet.
Investigate the leaking condition of pipes buried under the road and mark the ground where water may leak.
5. Conduct relevant tests on pipes
The PQWT leak detection trolley can play a greater role in the complex water leakage anomaly zone and noise interference zone found, and can carry out leak detection operations with unmanned accuracy. When automatic analysis is performed, the sound of water leakage is detected and the leakage point is determined by automatic calculation of the relevant peak value.
6、Leakage point confirmation and leak location
For the water leakage abnormalities or areas that have been found, organize higher technical level and experienced personnel to make abnormal judgments, eliminate abnormal interference, and confirm whether it is a water leakage abnormality. If it is a water leakage abnormality, then the leak point will be accurately located.
7. Leak recheck after repair
After repairing the water leakage point in the work area, carry out water leakage detection in the area again to find out the accurate positioning of the leakage point. If there is no abnormal water leakage area, the leak detection work is finished.
