When your company encounters abnormal situations in the water supply network such as underground pipeline leaks, fire pipes not maintaining pressure, water meters too fast, and unclear pipelines, Huaxiang Pipeline Leakage Detection Company welcomes you to call for consultation. 90% of the customers we encounter have the same question, 'Where did the unit leak several tens of tons (some even hundreds of tons) of water?'. From the general perspective of customers, it is reasonable for water to come up from the ground when there is so much leakage! But why can't we see any trace from the ground. Originally, over 90% of water pipe leaks would not surface on the ground. Leak testers have summarized the following aspects in their actual work. Reason 1: Most water pipe leaks gradually turn from small leaks to large leaks. The soil around the leak point is washed away by water for a long time, causing underground leaks. The water is directly absorbed by the earth. Water pipe leaks like a huge water ball, and the surface is like a large sponge. How much water can be absorbed. Reason 2: Some leakage points are located in the green belt and soil, and there is no visible water flow near the sewage well. A customer asked, "Why doesn't the soil sink if there is a leak on the ground?" Because the ground will not collapse when the groundwater is full, unless the groundwater is dry. Some cities have sinkholes formed by excessive collection of groundwater. Reason 3: Some water leaks are directly discharged from the sewer because the water level in some pits is too high, and there are often no visible traces of flowing water. In real leak detection cases, many cellar wells have high water levels, and based on experience, it is judged that the water from the leak point flows in. Many customers do not believe it, thinking that 'if there is a leak of water coming in, then the water in the cellar should overflow'. But the fact is that even if you use a water pump to pump water all afternoon, it won't be able to drain it completely. Reason 4: In the leak detection case, it was found that a small portion of the water leakage was directly discharged into the adjacent river channel, especially since the river channel is horizontally and geologically soft, which increases the possibility of underground drainage. The tap water transported through underground pipelines in the community, but?? How long does it take for water leakage to occur, and it will be noticed that there may not be any signs on the surface when the leakage occurs. Even if water seeps out from the surface, the seepage point may not necessarily be the leakage point, especially when there is a cement or other covering layer on the ground.

Long term fire water pipe leakage detection, water pipe leakage detection, household water pipe leakage detection, house water pipe leakage detection, underground pipeline leakage detection, underground pipeline water pipe leakage detection, underground pipeline detection technology, water pipe leakage maintenance, etc. The "running, emitting, dripping, and leaking" of water is a long-term challenge faced by urban water companies, property communities, and large enterprises and factories. The waste of water is not only a waste of precious natural resources, but also causes significant economic losses and burdens to urban water companies, property communities, enterprises and institutions. The leakage of fire water pipes poses a significant hidden danger. Therefore, accurate leak detection equipment and correct and scientific leak detection methods are needed by various enterprises and institutions. The generation of water leakage sound waves: Once the water supply network under a certain pressure is damaged and leaks, due to the pressure difference inside and outside the pipe, water will escape from the damaged point and have a certain speed. The escaping water will produce two mechanical motion processes. Fire water pipeline leakage detection can basically detect the planar projection position of underground pipelines on site through various geophysical methods, and mark various characteristic point numbers and measurement marks such as inflection points, tees, branch points, straight points, and variable diameter points on the ground with paint. Then use a total station to measure the plane coordinates and ground height of each detection point.

Dongguan Huaxiang Pipeline Leakage Detection Co., Ltd. believes that water leakage in the water supply network is a common problem in the water supply industry. Pipeline leakage not only wastes precious freshwater resources, but also brings huge economic losses to water supply enterprises. It is necessary to take practical and effective measures to control it. Proactively carrying out pipeline leak detection work is an important way to reduce pipeline leakage. Leak detection technology and equipment: The leak detection work of Dongguan Huaxiang Pipeline Leakage Detection Co., Ltd. mainly relies on the sound listening method, and the equipment includes listening rods, leak detectors, related instruments and auxiliary equipment, and pipeline instruments. The main equipment is introduced as follows: Listening rod: mainly used for listening to valve plugs and determining leakage points. It is not used to detect leakage points, but is a device that captures the size and authenticity of leakage sounds in pipelines. It's like a doctor's stethoscope, used frequently and with good results. Leak detector: mainly used for listening to sounds on road surfaces, it is a device that captures water leakage sounds on road surfaces. It usually has a good leak detection effect on cement road surfaces and when pipelines are not buried deep, but has poor detection effect on green belts, dirt roads, etc., and sometimes cannot be detected at all. It is an essential tool for leak detection. Correlation instrument: It does not rely on human hearing, as long as the on-site conditions (such as pipe material, pipe diameter, distance between two sensors) are input, the instrument will automatically calculate and determine the location of the leakage point. It is mainly used for pipelines and green belts crossing rivers, bridges, and houses, as well as buried pipelines. Sometimes it is also used to check and judge abnormal leakage points, and is rarely used in other times. Instruments are essential tools for searching for unknown pipelines, and our company uses pipeline instruments from Reddy Corporation in the UK. It plays a crucial role in locating the direction of unknown pipelines. The technical process of leak detection is a systematic project that requires comprehensive and scientifically reliable technology. Our company's leak detection mainly relies on acoustic detection technology as the core, which is widely used in area detection and evaluation, leak confirmation, and leak point location. The adopted leakage investigation technology process is as follows: regional leakage condition assessment - usually based on the available information, the leakage condition of the area is evaluated and a leak detection plan is formulated. Leakage assessment and detection in the district - environmental investigation, valve plug listening, road listening, relevant analysis, etc. Abnormal water leakage detection, confirmation and positioning of water leakage points - using drilling equipment to accurately locate water leakage points at close range and high frequency through water leakage sound, with a requirement of ≤± 1m. Water leakage measurement and repair - using measuring equipment to measure water leakage and repair the leakage points. Analysis of Leakage Causes - Analyze the pipe material, diameter, burial depth, shape, leakage amount, and leakage causes of the leakage point, and archive them together with pictures. Archive (computerized management)

Out of the 290 identified leakage points, the one with the lowest leakage rate was a fracture at the weld seam of a municipal DN600 steel pipe, with a leakage rate of 58.50m3/h. The one with the lowest leakage rate was a fire hydrant in a residential area, with a leakage rate of only 0.01 m3/h; The most difficult to identify leak point is a DN300 cast iron pipe in a certain garden, buried at a depth of 1.9m, with large and small ends cracked and a leakage rate of 31.2 m3/h. In addition, a DN100 steel pipe in the airport community, buried at a depth of 2.3m, has a broken weld seam and an unmeasured water volume, both buried at a depth of about 2.0m. The most easily identifiable leakage point is the DN50 and DN25 galvanized steel pipes buried within 0.5m. The leakage point in the aforementioned garden happened to crack at the big and small ends, and the pipe was enclosed by a culvert and soaked in water, so there was only a very faint sound on the ground. The DN100 leakage in the airport community is difficult to identify due to its large burial depth of 2.3m, the entire pipe is broken, and a cavity has formed around the leakage point. According to the excavation results on site, the majority of leaks are caused by corrosion perforation and interface leakage. One reason is that the pipeline has been buried for a long time and is severely corroded, leading to water leakage; Another reason is poor construction quality and inadequate anti-corrosion, which leads to water leakage; Fire hydrant leakage accounts for 15.17% of all leakage points, which is caused by poor sealing at the bottom and water leakage from the drain hole on the base. Such incidents have attracted high attention from our company; Welding seam leakage accounts for 8.62%, which is caused by pipeline leakage due to construction quality. In summary, while strengthening leak detection work, it is necessary to enhance the management of pipeline construction quality. 4、 Experience and understanding of leak detection work: It is important to be familiar with the condition of urban water supply networks through environmental investigations, otherwise it will be difficult to carry out leak detection work effectively. The purpose of environmental investigation is to clarify the direction, material, and diameter of pipelines. In addition, it is necessary to trace the source of the clean water that appears in sewage wells and cable wells. The effectiveness of environmental investigation directly affects the efficiency of leak detection. Correctly distinguishing between leakage sounds and "false sounds" is a very important part of leak detection work. Everyone has different judgments about leakage sounds. During the leak detection process, the leak detection team is required to pay special attention to the following situations on the basis of mutual inspection. The sound of water leakage varies among different pipes. Metal pipes have a high frequency of water leakage, while non-metallic pipelines have a low frequency of water leakage. The order of arrangement is: steel pipes>cast iron pipes>plastic pipes>cement pipes. The socket, branch pipe, and elbow have a certain impact on the sound of water leakage. The socket has a damping effect on the sound of water leakage, the branch pipe has a diversion effect on the sound of water leakage, and the elbow is prone to producing false sound of water leakage. The pressure of the pipeline has an impact on the sound of water leakage. When the pipeline pressure is above 2.5kg/cm2, the sound of water leakage is easy to capture, while when the pipeline pressure is below 1kg/cm2, the sound of water leakage is very small and difficult to detect. Reasonable use of leak detection equipment. Leak detection personnel must have a good understanding of the performance of various leak detection equipment and be able to use them reasonably to solve complex water leakage problems. Classify and organize the leak detection results to promote pipeline management while reducing leakage consumption. Our company attaches great importance to categorizing and organizing leak detection results, and carefully analyzing them. At present, we record the causes, pipe diameter, pipe material, burial depth, leakage volume, and leakage point shape of the identified leakage points, and input them into the computer for management and archiving.
