隨著PE管道在天然氣及供水行業(yè)的進(jìn)一步普及，燃?xì)庵?低壓管網(wǎng)由PE管逐步取代鋼管及鑄鐵管;由于PE管不導(dǎo)電，不導(dǎo)磁，無(wú)法對(duì)PE管進(jìn)行追蹤，給日后的管道維修帶來(lái)不便，因此示蹤線也隨之出現(xiàn)。

With the further popularization of PE pipes in the natural gas and water supply industries, PE pipes will gradually replace steel pipes and cast iron pipes in the gas medium / low pressure pipe network; Since the PE pipe is non-conductive and non-magnetic, it is impossible to track the PE pipe, which brings inconvenience to the pipeline maintenance in the future, so the tracing line also appears.

目前市場(chǎng)上常用的“示蹤線”有銅包鋼材質(zhì)示蹤線，薄膜鋼絲壓制示蹤線，電線示蹤線。“管道示蹤線”用于對(duì)PE管道的探測(cè)、追蹤及定位;”示蹤線”同PE管一起鋪設(shè);一般會(huì)采用金屬線芯，通過(guò)探測(cè)設(shè)備給“金屬線”施加信號(hào)，由探測(cè)接收機(jī)接收信號(hào)，從而找到示蹤線的準(zhǔn)確位置，即同步追蹤到PE燃?xì)夤艿赖木唧w位置;以便于對(duì)PE管道進(jìn)行改造及維修。

At present, the commonly used "tracing lines" in the market include copper-clad steel material tracing lines, film steel wire pressing tracing lines, and wire tracing lines. "Pipeline tracing line" is used to detect, track and locate PE pipelines Tracer line "shall be laid together with PE pipe; Generally, the metal wire core is used to apply signals to the "metal wire" through the detection equipment, and the signal is received by the detection receiver, so as to find the accurate position of the tracer wire, that is, to synchronously track the specific position of the PE gas pipeline; So as to facilitate the reconstruction and maintenance of PE pipes.

PE外保護(hù)層，絕緣、防腐、防水、抗老化?銅層，增強(qiáng)導(dǎo)電性，提高電信號(hào)鋼芯，增強(qiáng)線體強(qiáng)度，雙線連體結(jié)構(gòu)，可以使兩條線同等受力，受力均勻。

PE outer protective layer, insulation, anti-corrosion, waterproof and anti-aging? The copper layer enhances the conductivity, improves the steel core of the electric signal, and enhances the strength of the wire body. The double wire connected structure can make the two wires bear the same force and the force is uniform.

特點(diǎn)：1.電阻??；2.抗拉強(qiáng)度高；3.抗腐蝕和抗老化性能強(qiáng)；4.雙線優(yōu)勢(shì)；5.連接處有專用防護(hù)接頭連接。

Features: 1. Low resistance; 2. High tensile strength; 3. Strong corrosion and aging resistance; 4. Double line advantage; 5. There are special protective joints at the connection.

連接方式相關(guān)的示蹤線有專用的防護(hù)接頭，用于線與線之間的連接，接頭具備防水防腐的密閉腔體，將示蹤線裸露線頭放置于密閉腔體內(nèi)，從而保護(hù)裸露的示蹤線頭無(wú)法被腐蝕;接頭由PE材料制造，本身具備抗腐、抗老化的能力。

The tracer wire related to the connection mode has a special protective joint for the connection between wires. The joint has a waterproof and anti-corrosion sealed cavity. The exposed wire head of the tracer wire is placed in the sealed cavity, so as to protect the exposed tracer wire head from corrosion; The joint is made of PE material and has the ability of anti-corrosion and anti-aging.

薄膜示蹤線和電線示蹤線的連接方式:將兩個(gè)線頭擰在一起，一般選用熱收縮管或防水膠布做為接頭的處理，防腐及防水效果根據(jù)熱縮管的材質(zhì)及施工效果決定。

Connection method of film tracing line and wire tracing line: the two wire ends are screwed together. Generally, heat shrinkable pipe or waterproof tape is used as the joint treatment. The anti-corrosion and waterproof effects are determined according to the material and construction effect of heat shrinkable pipe.

探測(cè)性相關(guān)示蹤線:常規(guī)鋪設(shè)，埋深≤1.8米時(shí)，有效探測(cè)距離在1000米內(nèi);非開挖鋪設(shè)，埋深≤4米時(shí)，有效探測(cè)距離在500米;非開挖鋪設(shè)，埋深s7米時(shí)有效探測(cè)距離在300米。

Exploratory related tracing line: it is laid conventionally, and when the buried depth is ≤ 1.8m, the effective detection distance is within 1000m; For trenchless laying, when the buried depth is ≤ 4m, the effective detection distance is 500m; For trenchless laying, the effective detection distance is 300 meters when the burial depth is S7 meters.

電線示蹤線和以上類同，但是非開挖鋪設(shè)要用到截面積在6平方以上的電線，成本造價(jià)不適宜。更多關(guān)于示蹤線的信息獲取就來(lái)我們網(wǎng)站http://bjhuishi.com吧。

The wire tracing line is similar to the above, but the non excavation laying requires wires with a cross-sectional area of more than 6 square meters, and the cost is not appropriate. For more information about tracer lines, please visit our website http://bjhuishi.com Right.
