First, due to its low strength, mark and trace wire damage is a common occurrence.
Second, the lost of on-site construction drawings and materials, making it difficult to locate.
Third, because the exact position of the PE pipe in the municipal construction is not clear. It is easy to cause cutting during the construction process.
Therefore, before construction, it is necessary to detect the exact location of the existing underground PE pipeline.
Then avoid underground pipelines. If you accidentally dig the underground PE pipeline, it will cause water leakage, air leakage, and even gas explosion accidents.
However, due to the non-conductive and non-magnetic properties of PE pipes. It is difficult to use the battery wave method for detection.
