Find professional teams for underground pipe leakage detection, saving both time and effort. Dongguan Huaxiang Pipeline Detection Co., Ltd. is a high-standard enterprise that has been dedicated to underground pressure pipeline damage detection services for a long time. Their service scope includes underground tap water leakage detection, underground fire fighting tap water detection, fire pipeline repair, pipeline detection and measurement, professional underground pipeline leak detection, and fire water leak detection, etc.

When detecting leak noise, it's possible for small leaks to be located at the sound point, but excessive noise can increase the difficulty of direct and indirect sound detection. Weather conditions with wind, traffic noise, high flow rates, and pumps can all cause issues in the detection process. With over a decade of technical experience and the use of detection equipment, we can quickly pinpoint the location of the leak. Leak Detection

Sound Detection

The principle of acoustic detection is that different frequencies of "leak noise" are produced when water flows out through the pores of a pipeline, with the frequency determined by water pressure, the size and shape of the leak point, the material of the pipeline, and the filling material of the ground. Indirect acoustic detection using ground microphones can be used to detect low-frequency leakage noise passing through the ground. However, since this frequency range also includes footsteps and traffic noise, achieving satisfactory results requires an experienced inspector to conduct the detection.

Leak Detection Equipment

Most commonly used leak detection equipment operates on acoustic principles, although leak detection devices based on other principles are emerging, but are still less commonly used in our country. To better conduct leak detection, it is also necessary to equip auxiliary devices such as pipeline meters.

1) Audio Stick

The Leak Stick is an original leak detection device, consisting of a rod and an earpiece. It's affordably priced, easy to use, and still plays a significant role in leak detection operations.

2) Electronic Listening Device

The electronic sound level meter is an extension of the sound stick technology, commonly abbreviated as a sound level meter. It consists of a probe, a main unit, and an earphone set.

The leak detection method of the sound listening instrument is basically the same as that of the listening rod. Individually listen for any leak sounds in the accessories of the pipes in the tested area, and preliminarily determine which section of the pipe has a leak.
