When laying polyethylene gas pipelines, tracer lines should be laid at the top of the pipeline along with the direction of the pipeline. The tracer line should use 2 × 2.5mm2 double wire single core copper wire with a well insulated protective layer on the outside. The tracer wire should be effectively connected, and the double wire winding soldering process should be used at the copper wire joint to ensure conductivity. Wrap the external insulation with tape and seal it with a heat shrink sleeve. The sealing end must be 20mm larger than the tape wrapping end. Signal source wells should be installed every 2km along the direction of the polyethylene gas pipeline. Inspection wells and other facilities can serve as signal source wells. There is a signal connector inside the signal source well, which is used to connect external signals for testing tracer lines. Electronic markers should be installed on gas pipelines. The memory of the electronic identifier can include the name of the pipeline ownership unit, pipeline diameter, installation or maintenance date, pressure rating system, name of the construction unit, and the relative position of the electronic identifier with the pipeline.

電子(zi)標(biao)識(shi)器(qi)應(ying)安(an)裝(zhuang)在以(yi)下(xia)位(wei)置：

Electronic markers should be installed in the following locations:
