可探测警示带以PVC薄膜为基材,具有优异的绝缘、耐燃、耐寒、耐电压、耐酸碱、耐溶剂等特征。它耐磨、耐侵蚀、耐油性佳,用于地面忠言区域标示,颜色有红、黄、蓝、绿、白、黑、黄与黑、绿与白、红与白供参考,顺应差别的需求。下面来讲讲可探测警示带作用及探测原理相关内容。
The detectable warning tape is made of PVC film, which has good insulation, flame resistance, cold resistance, voltage resistance, acid and alkali resistance, solvent resistance and other characteristics. It has good wear resistance, corrosion resistance and oil resistance. It is used for marking warning areas on the ground. The colors are red, yellow, blue, green, white, black, yellow and black, green and white, red and white for reference and adapt to different needs. Now let's talk about the function and detection principle of detectable warning tape.
为 ;と计艿涝谌蘸笤诵兄,不受人为的意外损坏,燃气规范划定,应在燃气管道的上方距管顶不小于300mm处敷设一条警示带,警示带上应标出醒目的提醒字样。例如:“下面是XXX公司燃气管道,请勿挖掘,联系电话:XXXXX等”。
In order to protect the gas pipeline from accidental human damage in the future operation, the gas specification stipulates that a warning tape shall be laid at the top of the gas pipeline not less than 300mm from the pipe top, and the warning tape shall be marked with striking words. For example: "The following is the gas pipeline of XXX company, please do not dig, contact number: XXXXX, etc.".
现在的地下管道探测仪可以很容易地准确测定埋地金属管道的位置和深度,但聚乙烯管道是绝缘体,因此,用通例的电磁法无法探测到聚乙烯管道,而用地质雷达等要领,从手艺上是可行的,但探测本钱较大。因此,为能接纳通例要领探测到埋地聚乙烯管道的位置和深度,要求在敷设聚乙烯管道的同时敷设一条金属示踪线。
The current underground pipeline detector can easily and accurately determine the position and depth of buried metal pipelines, but polyethylene pipelines are insulators. Therefore, polyethylene pipelines cannot be detected by conventional electromagnetic methods, while geological radar and other methods are technically feasible, but the detection cost is relatively high. Therefore, in order to detect the position and depth of buried polyethylene pipes by conventional methods, it is required to lay a metal tracer line while laying polyethylene pipes.

敷设示踪线是为了管道探测利便,准确地描绘出聚乙烯管道的走向及位置。现在我国均是将金属导线包覆在警示带中,故又称金属示踪带,它起到了示踪线和示踪带的双重作用。其原理均是通过电流脉冲感应作用,用响应的探测仪器举行检测吸收这个电流信号来确定金属示踪带的走向和位置,并凭证己测定金属示踪带的位置来判断聚乙烯管道的走向和位置。
The trace line is laid to facilitate the pipeline detection and accurately depict the direction and position of the polyethylene pipeline. At present, the metal wire is wrapped in the warning tape in China, so it is also called the metal tracing tape, which plays a dual role of the tracing wire and the tracing tape. Its principle is to determine the direction and position of the metal tracer belt by detecting and receiving the current signal with the corresponding detection instrument through the induction of current pulse, and determine the direction and position of the polyethylene pipe according to the position of the metal tracer belt that has been measured.
我们的可探测警示带不但色泽鲜艳、厚薄匀称并且分切整齐并具有很强的拉伸力,本产品具有金属可探测功效,一样平常铺设在地下管道上,作为施工时可以让施工职员准确探测到地下管道所处的位置,是避免管道因施工不小心造成的破损和损伤的有用标记。更多相关事项就来我们网站咨询相识吧!
Our detectable warning tape is not only bright in color, uniform in thickness, but also neatly cut and has a strong tensile force. This product has the metal detectable function and is generally laid on the underground pipeline. It can be used as an effective sign to prevent the damage and damage caused by careless construction.
