Routine process of external network water pipe leak detection

As we all know, if a water pipe leaks, it can cause us a lot of trouble. To solve the water leakage problem, one of the first tasks is to carry out water pipe leak detection, and only after the location of the leak is clear, can we start to repair it. So, what is the way to detect a water pipe leak? We may not know much about this, so let us introduce it below.

(A) Collecting information about the pipe

Collect the drawing information and water consumption information of the pipeline to be tested, and arrange the technical personnel who are familiar with the location of the pipeline to go to the site to point out the plane position, burial depth, material, diameter and other related information of the pipeline.

(B) Survey of the regional pipeline environment

Fully understand the site situation and make preparations for the next step of leak detection such as construction arrangement and method selection, including pipeline network environment survey, subsidiary equipment survey, water use survey and drainage survey. (If you are not sure about the location of the pipeline, you need to determine the direction and burial depth of the pipeline with the help of pipeline meters)

(C) detailed investigation of water leakage and accurate positioning

In the work area, daytime fire hydrants, valves, water meters and open pipes in the area using Pipeline leakage detector for 100% direct listening to listen to the sound waves propagating from the leakage point to the pipeline structure to find the leakage anomaly. In general, the basic detection method is, connect the pipeline leakage detector host, headphones, sensors. Turn on the Pipeline leakage detector switch, wear the headset, the sensor placed on the road above the pipeline, placed 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, multi-point repeatedly to compare, compare 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, the larger point may instead be on the side of the road above the pipe, rather than being the pipe Above the road, so the location of the pipeline to know, in addition to the tee, bend, water pressure, burial depth, buried layer, etc. will have an impact on the detection to take these into account.
