隨著PE管道在天然氣及供水行業的進一步普及，燃氣中/低壓管網由PE管逐步取代鋼管及鑄鐵管；由于PE管不導電，不導磁，無法對PE管進行追蹤，給日后的管道維修帶來不便，因此地埋示蹤線也隨之出現。目前市場上常用的“示蹤線”有銅包鋼材質示蹤線，薄膜鋼絲壓制示蹤線，電線示蹤線。

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.

示蹤線的發展已經歷三代：

The development of trace lines has gone through three generations:

1.代示蹤線：是由鋁箔和塑料薄膜的母體組成，鋁箔主要是傳輸信號，母體是固定鋁箔。這種示蹤線缺點：鋁箔強度非常低，即使在生產，運輸過程中也很容易斷裂，輔設易損傷，同時鋁箔的電阻非常大，有效探測距離和深度有限。

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.第二代示蹤線：是由鋼絲和塑料薄膜壓制而成，該示蹤線由鋼絲為導體，電阻大，探測距離有限，難以滿足實際需要。

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.第三代示蹤線：是由銅包鋼金屬線芯和PE外保護層組成，外觀成線狀。

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.

示蹤線的作用

The role of trace lines

“示蹤線”用于對PE管道的探測、追蹤及定位；

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

“示蹤線”同PE管一起鋪設；一般會采用金屬線芯，通過探測設備給“金屬線”施加信號，由探測接收機接收信號，從而找到示蹤線的準確位置，即同步追蹤到PE燃氣管道的具體位置；以便于對PE管道進行改造及維修。更多相關產品信息就來咨詢我們http://www.qzxiesheng.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.
