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，因此示踪线也随之出现。

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。“管道示踪线”用于对PE管道的探测、追踪及定位;”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。

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外保护层，绝缘、防腐、防水、抗老化?铜层，增强导电性，提高电信号钢芯，增强线体强度，双线连体结构，可以使两条线同等受力，受力均匀。

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.

特点：1.电阻小；2.抗拉强度高；3.抗腐蚀和抗老化性能强；4.双线优势；5.连接处有专用防护接头连接。

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.

连接方式相关的示踪线有专用的防护接头，用于线与线之间的连接，接头具备防水防腐的密闭腔体，将示踪线裸露线头放置于密闭腔体内，从而保护裸露的示踪线头无法被腐蚀;接头由PE材料制造，本身具备抗腐、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.

薄膜示踪线和电线示踪线的连接方式:将两个线头拧在一起，一般选用热收缩管或防水胶布做为接头的处理，防腐及防水效果根据热缩管的材质及施工效果决定。

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.

探测性相关示踪线:常规铺设，埋深≤1.8米时，有效探测距离在1000米内;非开挖铺设，埋深≤4米时，有效探测距离在500米;非开挖铺设，埋深s7米时有效探测距离在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.

电线示踪线和以上类同，但是非开挖铺设要用到截面积在6平方以上的电线，成本造价不适宜。更多关于示踪线的信息获取就来我们网站http://www.binzhouhengtong.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://www.binzhouhengtong.com Right.
