示踪线看法
Tracer Line Concept
随着PE管道在自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管举行示踪，给日后的管道维修带来未便，因此示踪线也随之泛起 。现在市场上常用的“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 pipelines in the natural gas and water supply industries, PE pipes are gradually replacing steel pipes and cast iron pipes in gas medium/low pressure pipeline networks; Due to the non conductivity and non magnetism of the PE pipe, it is not possible to trace the PE pipe, which brings inconvenience to future pipeline maintenance. Therefore, tracing lines also appear. The commonly used "tracer wires" in the current market include copper clad steel material tracer wires, thin film steel wire pressed tracer wires, and wire tracer wires.
示踪线作用
Tracer line effect
“示踪线”用于对PE管道的探测、示踪及定位；
The "tracer line" is used for detecting, tracing, and locating PE pipelines;
“示踪线”同PE管一起铺设；一样平常会接纳金属线芯，通过探测装备给“金属线”施加信号，由探测吸收机吸收信号，从而找到示踪线的准确位置，即同步示踪到PE燃气管道的详细位置；以便于对PE管道举行刷新及维修 。
The "tracer line" is laid together with the PE pipe; Generally, metal wire cores are used to apply signals to the "metal wire" through detection equipment, and the detection receiver receives the signal to find the accurate position of the tracing line, that is, synchronously tracing to the specific position of the PE gas pipeline; To facilitate the renovation and maintenance of PE pipelines.
示踪线的生长已履历三代：
The development of tracer 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，母体是牢靠铝箔 。这种示踪线弱点：铝箔强度很是低，纵然在生产，运输历程中也很容易断裂，辅设易损伤，同时铝箔的电阻很是大，有用探测距离和深度有限 。
1. First generation tracer line: It is composed of a matrix of aluminum foil and plastic film, with aluminum foil mainly used for signal transmission and the matrix being fixed aluminum foil. The disadvantage of this tracer line is that the strength of aluminum foil is very low, and even during production and transportation, it is easy to break, and the auxiliary equipment is easily damaged. At the same time, the resistance of aluminum foil is very high, 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，难以知足现实需要 。
2. Second generation tracer line: It is made by pressing steel wire and plastic film. The tracer line is made of steel wire as the conductor, with high resistance and limited detection distance, making it difficult to meet practical needs.
3.第三代示踪线：是由铜包钢金属线芯和PE外�；げ阕槌�，外观成线状 。以下以HX-13II示踪线为例
3. Third generation tracer wire: It is composed of copper clad steel metal wire core and PE outer protective layer, with a linear appearance. Taking the HX-13II tracer line as an example

The tracer line has a special protective connector for the connection between lines. The connector has a waterproof and anti-corrosion sealed chamber. The exposed wire ends of the tracer line are placed in the sealed chamber, so as to protect the exposed missing wire ends from corrosion. The connector is made of PE material and has corrosion resistance and aging resistance.
