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.
地面标记
Ground signs
在地面响应位置上举行标记,埋设标记、标记砖、标记贴等 。这种方法直观易找,但受地面情形限制,如在快速路上很难设置 。遇蹊径维修或拆迁等情形,还会大宗丧失标记 。现阶段地面标记物均接纳以上标记 。
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.
金属薄膜示踪带
Metal film tracer tape
在PE管道上方敷设金属薄膜示踪带,然后用探管仪举行探测 。示踪带中的金属薄膜具有导电性,理论上可以体现出金属管的特征,但现实上由于金属薄膜的截面积太小,导电性欠好,受周围金属管道滋扰大,致使探测效果很是差,只有在滋扰小且距离地面很近的地刚刚气被探测到 。并且辐射历程中 ,每100米需举行一次毗连 ,如毗连不当 ,在后期使用历程中因土壤沉降会导致示踪带断裂 ,进而无法检测 。
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.
燃气示踪线
金属示踪线
Metal tracer
为提高示踪物体的导电性,我们曾使用金属示踪线来替换金属薄膜示踪带 。由于示踪线的线芯是铜,且具有一定的截面积,因此导电性显着好于薄膜示踪带,尤其在刚埋下去的时间,探测效果较好 。但随着时间延伸,示踪线袒露出很大问题 。a.示踪线一旦有断点,如施工时被挖断自然锈蚀、毗连时没接牢等,从断点往后就无法被探测到 。b.相关于其他地下管道或线路,示踪线的导电性没有它们好,因此造成探测信号过于微弱,以于混淆管道位置 。并且抗拉性能差 ,在定向钻穿越中无法敷设 。
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.
