Warning tape, also known as marking tape, is widely used for warning protection of the fifth class transportation system and information transmission system related to the national economy and the people's livelihood, such as various directly buried gas pipelines, oil pipelines, urban water supply and drainage and other gas and liquid pipeline transmission systems, power cables and communication optical cables. The following is a brief introduction to cable warning tape products.

The cable warning tape has an obvious protective and warning effect on various complex urban pipe networks, construction sites, road construction sites and traffic accident sites, as well as directly buried pipelines in construction sites and fields. It is convenient for construction, construction and buried pipelines are carried out at the same time, buried between the underground and the pipeline, and laid at 30-50cm above the pipeline, playing a warning sign role, It is an economical, effective, simple and easy product for safety protection of all kinds of directly buried pipelines and cables, so as to avoid unnecessary damage to pipelines in the future excavation and construction, resulting in major accidents and huge property and economic losses due to accidental damage.

There are two types of warning tape: one is ordinary warning tape; The other is metal embedded detectable warning tape, also known as tracer tape (with stainless steel metal warning tape). With the continuous development of social economy, PE, PPR, PVC and other plastic pipes are increasingly used in the construction of underground pipe network, and the detection instrument can not detect the pipeline direction at all.

The metal warning tape can solve the problem that the pipeline cannot be detected. Moreover, the product is made of high-strength and aging resistant polymer materials, with PE, PP and OPP as the main raw materials and processed through anti-corrosion treatment. It has good corrosion resistance, bright color and eye-catching. It is laid underground for 50 years without corrosion and fading, and meets the requirements of long-term buried quality.

3. During detection, connect one end of the transmitter of the pipeline detector to the tracer line conductor, and the other end of the transmitter is grounded. The grounding pile of the transmitter shall be vertical to the pipeline and as far away from the transmitter as possible, but shall not be connected to other pipelines to avoid signal interference.
