随着PE管道在天然气及供水行业的进一步普及，燃气中/低压管网由PE管逐步取代钢管及铸铁管；由于PE管不导电，不导磁，无法对PE管进行追踪，给日后的管道维修带来不便，因此地埋示踪线也随之出现。目前市场上常用的“示踪线”有铜包钢材质示踪线，薄膜钢丝压制示踪线，电线示踪线。

With the further popularization of PE pipes in the natural gas and water supply industries, PE pipes gradually replace steel pipes and cast iron pipes in the gas medium/low pressure pipe network; As PE pipe is non-conductive and non magnetic, it is impossible to track PE pipe, which will bring inconvenience to pipeline maintenance in the future, so buried trace lines also appear. At present, the commonly used "tracing lines" in the market include copper clad steel tracing lines, thin film steel wire pressing tracing lines, and wire tracing lines.

示踪线的发展已经历三代：

The development of trace lines has gone through three generations:

1.代示踪线：是由铝箔和塑料薄膜的母体组成，铝箔主要是传输信号，母体是固定铝箔。这种示踪线缺点：铝箔强度非常低，即使在生产，运输过程中也很容易断裂，辅设易损伤，同时铝箔的电阻非常大，有效探测距离和深度有限。

1. The first generation tracing line: It is composed of aluminum foil and plastic film parent. The aluminum foil is mainly used to transmit signals, and the parent is fixed aluminum foil. Disadvantages of this trace line: the aluminum foil has very low strength, which is easy to break even during production and transportation, and the auxiliary equipment is easy to damage. At the same time, the resistance of aluminum foil is very large, and the effective detection distance and depth are limited.

2.第二代示踪线：是由钢丝和塑料薄膜压制而成，该示踪线由钢丝为导体，电阻大，探测距离有限，难以满足实际需要。

2. The second generation of trace line: it is pressed by steel wire and plastic film. The trace line is made of steel wire as conductor, with large resistance and limited detection distance, which is difficult to meet the actual needs.

3.第三代示踪线：是由铜包钢金属线芯和PE外保护层组成，外观成线状。

3. The third generation tracer wire: It is composed of copper clad steel wire core and PE outer protective layer, and its appearance is linear.

示踪线的作用

The role of trace lines

“示踪线”用于对PE管道的探测、追踪及定位；

"Tracer line" is used for the detection, tracking and positioning of PE pipes;

“示踪线”同PE管一起铺设；一般会采用金属线芯，通过探测设备给“金属线”施加信号，由探测接收机接收信号，从而找到示踪线的准确位置，即同步追踪到PE燃气管道的具体位置；以便于对PE管道进行改造及维修。更多相关产品信息就来咨询我们http://www.lnszgh.com吧！

"Tracer line" shall be laid together with PE pipe; Generally, metal wire cores are used to apply signals to the "metal wire" through the detection equipment, and the detection receiver receives the signals to find the exact position of the trace line, that is, to synchronously track the specific position of the PE gas pipeline; In order to facilitate the transformation and maintenance of PE pipes.
