In order to ensure the conductivity, strength, corrosion resistance and durability of the trace wire, how to effectively test it? Next, the gas pipeline trace line manufacturer will talk about the relevant matters here.

Gas tracer wire is a product specially designed for locating and locating underground non-metallic pipelines. It effectively solves the problem that non-metallic pipelines cannot be detected with metal pipeline finder, and can be widely used for locating and locating underground non-metallic pipelines such as gas, water supply pipelines and drainage pipelines.

Tracer wire detection: After the pipeline is laid, the pipeline detector shall be used to test the detectability of the laid tracers to ensure that the metal wires have been connected properly, and the test results shall be recorded.

Connect the metal wire of the tracer wire with the transmitter input end of the pipe locator, and the transmitter grounding end should be as far away from the transmitter as possible. Use the grounding pile or pole grounding to reduce the grounding resistance. Use the receiver to detect and receive the transmitted signal. The displacement and buried depth of the pipeline can be found.

Generally, multi strand copper wires with a sectional area of more than 2.5 mm should be selected. When laying, the trace wire should be kept at the top of the pipe as much as possible. At the tee branch, the insulation layer of the wire joint should be stripped off, the copper core twisted together for several turns, and then the joint should be wrapped with insulating tape to maintain good conductivity;

A certain amount of wire head allowance shall be reserved for the trace wire, and the wire head shall not be covered by soil or sundries. In order to reduce the grounding resistance of the end of the trace wire that cannot go out of the ground, it is necessary to take good grounding measures to strip the insulation layer to expose the core wire for 30 cm. For the PE pipe laid by directional drilling, the wire with greater strength shall be selected to avoid being pulled off during construction, resulting in the inability to detect and locate;

When the diameter of the conductor is far less than the buried depth and the medium change of the ground medium and air is ignored, the trace line can be regarded as an infinite line in the uniform medium.
