The tracer wire laid along with the gas buried PE pipe is designed to make it easier to find the gas pipe in the future (an auxiliary means to find the pipe in the future). Let's take a look at the relevant content.

1. After the tracer wire is buried with the pipeline after installation, the underground pipeline detector (which is a little expensive, but it should be an appropriate facility in the gas industry, especially the production and operation Department) is used to check the integrity of the tracer wire during acceptance. The principle and practical method are very simple.

2. In trenchless Engineering (directional drilling operation), in order to ensure the integrity of the tracer wire, the specification of the tracer wire is usually 4.0 square meters of single core copper coin, which should be tied to the gas PE pipe to be dragged in with two lines, and dragged in with the pipe when dragging.

3. Because the tracer wire used in the pipeline search depends on the current in the closed circuit. Due to the resistance problem, the current intensity decreases with the increase of the distance between the detection point and the signal transmitter. Generally speaking, 2.5 square single core copper wire is used as the tracer wire, and the signal effective range radius of the transmitter is 300 meters (the better the tracer wire is, the greater the effective radius is).

The detection position of the continuous laying of the tracer wire can be directly set in the valve well and condensate well. If there is no valve well within 300 meters or other positions where the tracer wire can be detected, the tracer wire detection well should be set up separately; The inspection well shall be marked on the as built drawing for future use.

4. The installation of pipeline tracer wire is not a work with too high technical content. It should be tied to the gas pipeline (in principle, it should be tied directly above, because it also undertakes the task of measuring the buried depth of the pipeline). It should be handled well at the joint, such as using a special wiring sleeve; Tin welding is used to prevent the loss of conductivity at the contact due to the influence of underground humidity, soil acidity and other bad environments.
