Underground Gas PE Pipeline Detection Project

With the development of science and technology, the materials of urban underground pipelines are constantly changing. In the past, a large number of metal pipelines were used, but now in various pipe networks such as water supply, drainage, gas, heat, industry, oil and gas, the applications of non-metallic pipelines such as plastics (PE pipes, PVC pipes, etc.), ceramics and concrete are increasingly popular. Because these nonmetallic pipelines have the advantages of strong pollution resistance, light weight, low cost, non-corrosion, easy laying and maintenance, etc., they have been increasingly used to replace metal pipelines. The detection technology of underground metal pipelines has matured, but the detection of nonmetallic pipelines is still a technical problem at present, because nonmetallic pipelines are neither conductive nor magnetic, and are basically insulated, and common metal pipeline detectors cannot detect them, which brings great difficulties to determine the location and buried depth of underground nonmetallic pipelines, avoid damage caused by construction excavation, and manage and maintain the safety of pipe networks. How to detect nonmetallic pipelines quickly, accurately and conveniently has become an urgent problem to be solved.
