After the pipeline is laid, the detectability test of the laid detectable trace line shall be carried out with the pipeline detector to ensure that the metal wire has been connected properly, and the test results shall be recorded. Connect the metal wire of the tracer line with the transmitter input end of the pipe locator, and the transmitter ground end should be as far away from the transmitter as possible. Use the grounding pile or the grounding of the electric pole 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.

產品特點：防水好、示蹤快、防腐強、拉力大。

Product features: good waterproof, fast tracing, strong anti-corrosion and large tensile force.

適用范圍：燃氣、自來水、排水、污水等非金屬管道定向穿越工程施工。

Scope of application: gas, tap water, drainage, sewage and other non-metallic pipeline directional crossing engineering construction.

示蹤線以它防水更好、示蹤更快、防腐更強、拉力更大等特點被業界所青睞，是結合地下非金屬管道無法探測及使用現有電線、線纜等產品的優點及缺點加以繼承和改良的換代新型科技產品。它適用于：燃氣、自來水、排水、污水等地下非金屬管道的快速探測與精準定位。

Tracer wire is favored by the industry because of its better waterproof, faster tracing, stronger corrosion prevention and greater tensile force. It is a new generation of scientific and technological product that inherits and improves the advantages and disadvantages of existing wires, cables and other products that cannot be detected and used by underground non-metallic pipelines. It is suitable for rapid detection and accurate positioning of underground non-metallic pipelines such as gas, tap water, drainage and sewage.

管道示蹤線隨非金屬管道一起敷設，利用探測設備與示蹤線纜金屬線芯進行點對點信號交換，從而檢測出它存在于地下的準確位置，并可同步測判出非金屬管道的埋深、走向以及管徑的大小。示蹤線產品的問世及不斷研發，結合及各地方政府部門的相關要求，相信將會對我國今后繁榮的地下管網建設起到很好的促進作用。

The tracing line of the pipeline is laid together with the non-metallic pipeline, and the detection equipment is used to exchange point-to-point signals with the metal core of the tracing cable, so as to detect the exact location of it underground, and synchronously measure and judge the buried depth, direction and diameter of the non-metallic pipeline. The advent and continuous research and development of tracer line products, combined with the relevant requirements of the state and local government departments, are believed to play a good role in promoting the future prosperity of underground pipe network construction in China.
