燃氣地埋PE管隨管敷設的金屬示蹤線，目的是為了以后能更方便的找到燃氣管道（是以后找方便找管道的一種輔助手段)。下面燃氣示蹤線廠家為您進行講解。

The metal trace line laid along the gas buried PE pipe is intended to find the gas pipeline more conveniently in the future (it is an auxiliary means to find the pipeline more conveniently in the future). The manufacturer of gas trace line will explain it to you below.

1、金屬示蹤線安裝后隨管道埋地后，在驗收時應用地下管道探測儀（該儀器有點貴，但應是燃氣行業的應配設施，特別是生產運營部門）來檢驗示蹤線的完整性，原理及實用方法十分簡單。

1. After the metal trace line is installed and buried along with the pipeline, the underground pipeline detector (which is a little expensive, but should be a necessary facility in the gas industry, especially in the production and operation department) should be used to check the integrity of the trace line during acceptance. The principle and practical method are very simple.

2、在非開挖工程中（定向鉆作業)，為了保證示蹤線的完整性，示蹤線的規格通常采用40平方的單芯銅錢，且要用雙線，綁在將要拖入的燃氣PE管上，在拖管時隨管一同拖入。

2. In the trenchless project (directional drilling operation), in order to ensure the integrity of the trace line, the specification of the trace line is usually 40 square single core copper coin, which is tied to the gas PE pipe to be pulled in with two lines, and is pulled in with the pipe.

3、因在查找管線用到示蹤線時是依靠閉合電路中的電流來進行操作的，由于電阻問題，電流強度用隨著檢測點與信號發射機的距離增加而減弱。

3. As the tracing line is used to find the pipeline, the operation depends on the current in the closed circuit. Due to the resistance problem, the current intensity decreases as the distance between the detection point and the signal transmitter increases.

一般來說，25平方的單芯銅線作示蹤線，其發射機的信號有效范圍半徑為300米(示蹤線越好有效半徑越大)。示蹤線連續敷設檢測位置可直接設置在閥門井、凝水井內，如300米內沒有閥門井或其他可以檢測示蹤線的位置，應單獨設立示蹤線檢測井;檢測井應在竣工圖上標出，以方便以后使用。

Generally speaking, the 25 square square single core copper wire is used as the tracer wire, and the effective radius of the transmitter signal is 300 meters (the better the tracer wire is, the greater the effective radius is). The continuous laying detection position of the trace line can be directly set in the valve well and condensate well. If there is no valve well or other position where the trace line can be detected within 300 meters, the trace line detection well shall be set separately; The inspection well shall be marked on the as built drawing for future use.

示蹤線安裝不是技術含量太高的工作，要綁在燃氣管道上(原則上是綁在正上方，因為它還肩負著測管道埋深的任務)，在接頭處要處理好，如使用專用接線套管。更多相關內容就來我們網站進行http://www.scnu-graduate.com咨詢！

The installation of the trace line is not a work with too high technical content. It should be tied to the gas pipeline (in principle, it should be tied directly above, because it is also responsible for measuring the buried depth of the pipeline). It should be handled well at the joints, such as using special wiring sleeves. More relevant content will come to our website http://www.scnu-graduate.com consulting service
