Pipeline leak detector

Pipeline transported tap water, sometimes there will be leakage problems, and when leakage occurs, the surface does not necessarily have any signs, even if the water seeps out from the surface, the seepage point is not necessarily a leakage point, especially when the ground has a cement and other coverings. Pipeline leakage point detection methods are: listening method, acoustic vibration method, the method requires acoustic vibration pipe leak detector. So how can you find out the pipeline leak point with a pipe leak detector

1. Collect pipeline data to find the leak point. Collect drawings of the pipeline and water use data. Companies arrange for technical personnel familiar with the location of the pipeline to point out the relevant information about the pipeline.

2. Regional pipeline network environment survey The purpose of the pipeline network environment survey is to fully understand the site situation and prepare for the next step of the construction arrangement and method selection of the leak detection work. Including pipe network environment survey, subsidiary equipment survey, water consumption survey and drainage survey.

3. Leak survey. In the work area, 100% of hydrants, valves, water meters, and transparent pipes are directly listened to every day to listen to the sound waves from the leak point to the pipe structure to find abnormal leaks. Detailed records are kept of the number of foreign trades, their locations, the nature of the anomalies, the anomalies and their explanations.

Pipeline leak detector

At the top of the pipeline in the investigation area, use the pipeline leak detector to place sensors 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 pipeline leak detector, a single point in the leak signal is not meaningful, to repeatedly compare multiple points, 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 The road above the pipeline, 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.
