可探測警示帶以PVC薄膜為基材，具有良好的絕緣、耐燃、耐寒、耐電壓、耐酸堿、耐溶劑等特性。它耐磨、耐腐蝕、耐油性佳，用于地面警告區(qū)域標(biāo)示，顏色有紅、黃、藍(lán)、綠、白、黑、黃與黑、綠與白、紅與白供參考，適應(yīng)不同的需求。下面來講講可探測警示帶作用及探測原理相關(guān)內(nèi)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.

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.".

現(xiàn)在的地下管道探測儀可以很容易地準(zhǔn)確測定埋地金屬管道的位置和深度，但聚乙烯管道是絕緣體，因此，用常規(guī)的電磁法無法探測到聚乙烯管道，而用地質(zhì)雷達(dá)等方法，從技術(shù)上是可行的，但探測成本較大。因此，為能采用常規(guī)方法探測到埋地聚乙烯管道的位置和深度，要求在敷設(shè)聚乙烯管道的同時敷設(shè)一條金屬示蹤線。

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.

敷設(shè)示蹤線是為了管道探測方便，準(zhǔn)確地描繪出聚乙烯管道的走向及位置。目前我國均是將金屬導(dǎo)線包覆在警示帶中，故又稱金屬示蹤帶，它起到了示蹤線和示蹤帶的雙重作用。其原理均是通過電流脈沖感應(yīng)作用，用相應(yīng)的探測儀器進(jìn)行檢測接收這個電流信號來確定金屬示蹤帶的走向和位置，并根據(jù)己測定金屬示蹤帶的位置來判斷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.

我們的可探測警示帶不僅色澤鮮艷、厚薄均勻而且分切整齊并具有很強的拉伸力，本產(chǎn)品具有金屬可探測功能，一般鋪設(shè)在地下管道上，作為施工時可以讓施工人員正確探測到地下管道所處的位置，是防止管道因施工不小心造成的破壞和損傷的有效標(biāo)志。更多相關(guān)事項就來我們網(wǎng)站http://m.tjshouche.cn咨詢了解吧！

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.
