The Application of Transient Electromagnetic Method in Detecting the Corrosion of Heat Distribution Pipeline

Abstract:

Leakage of the heat distribution pipeline will seriously affect the safety of residents and cause economic losses. This paper presents the transient electromagnetic method (TEM) for detecting the corrosion of buried heat distribution pipeline, which mainly introduced the principle of the TEM to detect the pipeline and the general detection method. Combining with an instance of corrosion detection of buried heat distribution pipeline in a certain street in China Hohhot, the detection results were analyzed and the feasibility of this method was proved through excavation. The results show that the TEM can detect the uniform corrosion distribution of buried metal pipeline and it’s effective and practical for detecting the buried heat distribution pipeline. The TEM could provide a new method for guaranteeing the safe operation of the heat distribution pipeline.
