When abnormal gas pressure in the pipeline caused a gas leak, the laser methane telemeter was used to monitor it, and it was found that the instrument at the excavation site of the road construction sounded an alarm. After careful inspection and gradually approaching the location, it was determined that the pipeline was leaking. It was understood that the leakage of the pipeline at this location was caused by the use of excavators to clean up the remaining soil during road construction. When the pipeline was cleaned above the gas pipeline, the company's pipeline was accidentally damaged, causing gas leakage.
In the leak inspection and repair of buried pipelines, because the leaked gas rapidly diffuses into the air, the concentration is often too low and it is difficult to detect the leak point. The laser methane telemeter has an accuracy of ppm (parts per million) and can detect the air. Weak to 5ppm methane gas, by scanning the surrounding gas concentration and displaying on the screen to accurately locate the leakage point.
