Water supply pipes may leak during prolonged use, which is usually due to a number of factors. In this paper, we will discuss the main causes of water supply pipe leakage, including pipe corrosion, aging, poor pipe quality, poor construction quality and external environmental influences. At the same time, we will also introduce some effective leakage detection methods.
I. Main causes of water supply pipe leakage
Pipe corrosion and aging
With the passage of time, water supply pipes may be affected by underground soil and moisture and other factors, and gradually corrode and aging. Especially for some metal pipes, such as galvanized pipe, steel pipe, cast iron pipe, etc., more susceptible to corrosion and aging, resulting in leakage of pipe joints or even burst pipe.
Poor quality of pipe materials
If the quality of pipe materials and interface materials do not meet the standards, cracks, leaks and other problems are likely to occur. For example, some poor-quality pipes may rupture under high-pressure water flow or the working pressure of neighboring pipes.
Poor construction quality
During the construction of water supply pipes, if the foundation is not solid, the pipeline laying is not standardized or the backfill is not dense, etc., it may lead to problems such as uneven settlement of the pipeline, circumferential fracture or flexure at the big end, which may in turn lead to leakage.
External environmental impact
External environmental factors may also have an impact on the water supply pipeline, such as seasonal changes in temperature caused by changes in the mechanical structure of the pipeline and expansion and contraction interfaces; soil load or road heavy vehicles repeatedly on the pipeline caused by cracking pressure, etc., which will lead to pipeline leakage or pipe burst.
Pipeline network operation is unreasonable
The multi-stage pressurized pipeline system of some enterprises can easily lead to local pressure is too high, which in turn leads to problems such as pipe burst and leakage.
Second, the water supply pipe leakage detection method is introduced
Audio-audio detection method
Audio detection method is a method to determine the location of water leakage by picking up the sound of water supply pipe leakage. This method is simple to operate, convenient instrument, widely used in all types of pipeline leakage detection. Detection in the case of less environmental noise interference, including the valve spigot listening and ground listening to the sound of two methods. The former is used to pre-locate the clues and scope of water leakage, and the latter is used to pinpoint the location of the leakage point.
In the sound detection method, need to pay attention to the following points: first of all, to choose the appropriate instrumentation, such as listening stick or electronic leakage meter, etc.; secondly, to explore along the pipeline, pay attention to the collection of the leakage sound signal; finally, to carry out a preliminary analysis and judgment, to determine the scope of possible leakage points, for the subsequent precise positioning to provide a reference.
In short, the problem of water supply pipe leakage needs to be given sufficient attention. Understanding the main causes of water supply pipe leakage and taking corresponding measures for prevention and detection can help reduce the occurrence of water leakage. At the same time, in the use of various detection methods for water supply pipe leakage detection, you need to follow the corresponding operating standards and steps to ensure the accuracy and reliability of the detection results.
