When it comes to the detectable warning tape, the layman must not know it well, but the peers in the field of underground pipeline laying will certainly not feel strange. Detectable warning tape is a kind of warning tape that is buried 30-50 cm underground and on the surface of various pipelines and cables and acts as a warning sign. Its function is to enable construction personnel to correctly detect the position of pipes and cables, so as to avoid damage to pipes and other consequences.

Current underground pipeline detectors can easily and accurately determine the position and depth of buried metal pipelines, but polyethylene/olefin pipelines are insulators. Therefore, polyethylene/olefin 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/olefin pipeline by conventional methods, a metal warning tape is required to be laid at the same time as laying polyethylene/olefin pipeline.

Use of raw materials for detectable warning tape:  tape of Jinneng Power is made of high-strength, anti-aging PE, PP, OPP polymer materials with bright color and eye-catching, which can be laid underground for 50 years without corrosion and fading. However, the products produced by some other manufacturers on the market are either recycled materials with short life and no toughness, which will break with a little effort. Or they cut corners on printing, which makes the color dull and the font easy to be corroded.

The detectable warning tapes produced by regular manufacturers are strictly controlled in production process, and the thickness is strictly in accordance with the production requirements: the general specification is ≥ 12 wires, and the built-in detectable metal sensitivity and specification are completely up to standard, which can be easily detected by pipeline detection personnel. However, for some other products on the market, the production standards were lowered by cutting corners, and the thickness and specifications of the detectable warning tapes produced could not meet the detection standards, which naturally could not meet the requirements of large power companies.

The reason why detectable warning tapes can be used for power, gas and oil pipelines is the content explained above. Is it helpful to you? You can come to our website if you have any questions or ideas or needs http://webtest2.daoshangbao.cn Ask about it!
