Tracer Line Concept

隨著PE管道(dao)在(zai)天然氣及(ji)供(gong)水(shui)行業的(de)進(jin)壹步普及(ji)，燃氣中(zhong)/低(di)壓(ya)管(guan)網由PE管逐(zhu)步取代(dai)鋼管及鑄(zhu)鐵管；由於PE管不(bu)導電(dian)，不(bu)導磁(ci)，無法(fa)對PE管進(jin)行示(shi)蹤(zong)，給(gei)日後的(de)管道(dao)維修帶來(lai)不(bu)便，因此(ci)示(shi)蹤(zong)線(xian)也隨之(zhi)出(chu)現(xian)。目前(qian)市場(chang)上常用(yong)的“示(shi)蹤(zong)線(xian)”有(you)銅包鋼材質(zhi)示(shi)蹤(zong)線(xian)，薄(bo)膜(mo)鋼絲壓制(zhi)示(shi)蹤(zong)線(xian)，電(dian)線示(shi)蹤(zong)線(xian)。

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(shi)蹤(zong)線(xian)作用(yong)

Tracer line effect

“示(shi)蹤(zong)線(xian)”用(yong)於對PE管道(dao)的探(tan)測、示(shi)蹤(zong)及(ji)定(ding)位(wei)；

The "tracer line" is used for detecting, tracing, and locating PE pipelines;

“示(shi)蹤(zong)線(xian)”同PE管(guan)壹(yi)起鋪(pu)設；壹般(ban)會采(cai)用(yong)金屬線芯(xin)，通過探(tan)測設(she)備給(gei)“金屬線”施(shi)加(jia)信號(hao)，由探測接(jie)收(shou)機(ji)接(jie)收(shou)信號(hao)，從而找(zhao)到示(shi)蹤(zong)線(xian)的(de)準(zhun)確(que)位(wei)置(zhi)，即(ji)同步示(shi)蹤(zong)到PE燃氣管(guan)道(dao)的具(ju)體位(wei)置(zhi)；以(yi)便於對PE管道(dao)進(jin)行改造及維修。

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(shi)蹤(zong)線(xian)的(de)發(fa)展(zhan)已經(jing)歷(li)三代(dai)：

The development of tracer lines has gone through three generations:

1.代(dai)示(shi)蹤(zong)線(xian)：是由鋁箔(bo)和塑料薄(bo)膜(mo)的母體組(zu)成，鋁(lv)箔(bo)主要是傳(chuan)輸(shu)信號(hao)，母體是固(gu)定(ding)鋁(lv)箔(bo)。這種(zhong)示(shi)蹤(zong)線(xian)缺(que)點(dian)：鋁(lv)箔(bo)強度(du)非(fei)常低(di)，即(ji)使在(zai)生(sheng)產，運(yun)輸(shu)過程(cheng)中(zhong)也很容易(yi)斷(duan)裂(lie)，輔(fu)設易(yi)損(sun)傷(shang)，同時(shi)鋁(lv)箔(bo)的電(dian)阻非(fei)常大(da)，有效(xiao)探測距離和深(shen)度(du)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(dai)示(shi)蹤(zong)線(xian)：是由鋼絲和塑料薄(bo)膜(mo)壓制(zhi)而成(cheng)，該示(shi)蹤(zong)線(xian)由鋼絲為(wei)導體(ti)，電(dian)阻大，探測距離有限(xian)，難(nan)以(yi)滿(man)足(zu)實(shi)際需要。

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(dai)示(shi)蹤(zong)線(xian)：是由銅包鋼金屬線芯(xin)和(he)PE外保護層組成，外觀成(cheng)線(xian)狀。以(yi)下(xia)以HX-13II示(shi)蹤(zong)線(xian)為(wei)例(li)

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.
