At present, although there are various types of instruments (i.e. pipeline detectors) for detecting the trace line of PE pipeline, their principles are based on the electromagnetic field theory from the perspective of the principle of detection methods.

Polyethylene pipes (PE pipes for short) have been widely used in the construction of urban buried pipe networks in recent years due to their advantages such as convenient construction, lower project cost than steel pipes (below DN300), no corrosion and leakage, and less pollution to transported substances.

In particular, gas and water pipelines are widely used. At present, municipal small caliber buried pipelines have the tendency to replace steel pipelines. Although PE pipeline has many advantages, its low strength is its weakness. In the past municipal construction, the exact location of the pipeline is not very clear, so it is common for the pipeline to be cut and leaked by construction machinery, and the resulting gas leakage and explosion accidents also occur from time to time. Therefore, it is necessary to detect and calibrate the location of underground PE pipeline.

PE pipes are made of inert materials, which are non conductive and non magnetic. After being buried underground, there is no good method to directly detect their underground space position on the ground. In order to solve the problem that the location and buried depth of PE pipes can be detected on the ground after being buried, a conductor line (hereinafter referred to as the tracer wire) is often buried together with PE pipes during the laying construction, which is used to detect the location of PE pipes in the future. The tracer wire method is currently widely used at home and abroad.

The pipeline trace line shall be placed together with the pipeline during laying. The detection personnel of buried pipeline shall be trained and qualified before working. During detection, one end of the pipeline detector transmitter shall be connected to the trace line, and the other end of the trace line shall be grounded. Along the general direction of the pipeline, the pipeline position and depth shall be detected with the pipeline detector.

This is the end of the function and effect of the PE pipeline tracer. I hope you can fully understand it before using it to prevent problems from causing a decline in the project quality. More relevant information will come to our website http://webtest2.daoshangbao.cn Look!
