Fire protection pipelines are important facilities for safeguarding the lives of urban residents. Regular inspections of fire protection pipelines are necessary to prevent their use from being affected in times of crisis and causing further loss of life and property. Due to corrosion aging, load vibration, pipeline quality, construction quality, service life and other reasons, fire water pipelines are inevitably prone to leaks, and regular testing is very important.

The detection of fire pipeline leakage mainly adopts the method of listening to sound for leakage detection, and most of the instruments used are also based on detecting the sound of fire pipeline leakage. Due to the complexity of underground pipeline networks and the influence of various factors such as the sound transmission performance of pipes, leak detection work requires rich on-site experience and advanced instruments and equipment as guarantees. For some cases, methods such as gas tracing, ground penetrating radar, and infrared temperature measurement can also be used to detect pipeline leaks.

The detection of fire water pipes requires the detection of water leakage in fire water pipes. So, what are the methods for detecting water leakage in fire water pipes? The leakage point should be closed by closing the main valve of the fire pipe network, confirming the leakage section, and observing the ground to confirm the leakage point. Confirm that the valve can be closed, it is difficult to close. If the valve can be closed, the approximate area of the leak can be confirmed, and the ground condition above the pipeline should be carefully checked for any sinking, particularly wet, and whether there is stable clean water in the nearby sewer. This leakage detection method is suitable for the general public, with low technical content, but it is difficult to accurately locate the leakage point.
