The leakage of heating, oil, natural gas and other pipelines will not only cause resource loss and environmental pollution, but also easily cause fire and explosion. Due to the difference between the temperature of the medium in the tube and the environment and the temperature change caused by the evaporation of the leakage, the optical fiber can be sensed in time, so the optical fiber accompanied by the pipeline layout can also replace the inspection work of the staff on the pipeline, and the specific location of the leak can be notified to the staff in time.Distributed temperature sensing cable laying along the pipeline can detect the low temperature point when high-pressure gas leaks or the high temperature point when heating liquid leaks, and can quickly locate and guide emergency repair.
