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.
