Do you know the specific contents of several types of common trace lines? The following manufacturer of the gas trace line will answer the question for you, and I hope it can help you effectively.

地面標志

Ground signs

在地面相應位置上進行標記,埋設標志、標志磚、標志貼等。這種方式直觀易找,但受地面環境限制,如在快速路上很難設置。遇道路維修或拆遷等情況,還會大量丟失標志。現階段地面標記物均采用以上標志。

Mark on the corresponding position on the ground, and bury signs, sign bricks, sign stickers, etc. This method is intuitive and easy to find, but is limited by the ground environment, for example, it is difficult to set on the expressway. In case of road maintenance or demolition, a large number of signs will be lost. At present, the above signs are used for ground markers.

金屬薄膜示蹤帶

Metal film tracer tape

在PE管道上方敷設金屬薄膜示蹤帶,然后用探管儀進行探測。示蹤帶中的金屬薄膜具有導電性,理論上可以體現出金屬管的特性,但實際上由于金屬薄膜的截面積太小,導電性不好,受周圍金屬管道干擾大,致使探測效果非常差,只有在干擾小且距離地面很近的地方才能被探測到。而且輻射過程中，每100米需進行一次連接，如連接不當，在后期使用過程中因土壤沉降會導致示蹤帶斷裂，進而無法檢測。

The metal film tracing tape is laid above the PE pipe, and then the pipe detector is used for detection. The metal film in the tracer belt has conductivity, which can theoretically reflect the characteristics of the metal tube. But in fact, because the cross-sectional area of the metal film is too small, the conductivity is poor, and the interference from the surrounding metal pipes is large, the detection effect is very poor, and can only be detected in a place with small interference and close to the ground. In addition, during the radiation process, a connection is required every 100 meters. If the connection is improper, the tracer zone will be broken due to the soil settlement in the later use process, and thus cannot be detected.

金屬示蹤線

Metal tracer

為提高示蹤物體的導電性,我們曾使用金屬示蹤線來替代金屬薄膜示蹤帶。由于示蹤線的線芯是銅,且具有一定的截面積,因此導電性明顯好于薄膜示蹤帶,尤其在剛埋下去的時候,探測效果較好。但隨著時間延長,示蹤線暴露出很大問題。a.示蹤線一旦有斷點,如施工時被挖斷自然銹蝕、連接時沒接牢等,從斷點往后就無法被探測到。b.相對于其他地下管道或線路,示蹤線的導電性沒有它們好,因此造成探測信號過于微弱,以于混淆管道位置。而且抗拉性能差，在定向鉆穿越中無法敷設。

In order to improve the conductivity of the tracer, we have used metal tracer wire to replace the metal film tracer tape. Since the core of the trace wire is copper and has a certain cross-sectional area, its conductivity is obviously better than that of the film trace tape, especially when it is just buried, the detection effect is better. However, with the extension of time, the tracer line exposed a lot of problems. a. Once there is a breakpoint in the trace line, such as natural corrosion due to excavation during construction, and failure to connect firmly, it cannot be detected from the breakpoint onwards. b. Compared with other underground pipelines or lines, the conductivity of the trace line is not as good as them, so that the detection signal is too weak to confuse the pipeline position. Moreover, the tensile property is poor, and it cannot be laid in directional drilling crossing.
