With the continuous development of social economy, PE, PPR, PVC and other plastic pipes are more and more used in the construction of underground pipe networks. Detection instruments can't detect the direction of pipelines at all. Buried warning tapes can solve the problem that pipelines can't be detected. Moreover, this product is made of high-strength and aging resistant polymer materials, with PE, PP and OPP as the main raw materials.

use:

1. Check whether the signal access point is reserved and whether the installation method is correct.

2. Check whether the conductive wire in the warning tape can load detection signals, whether there is signal leakage, and whether sufficient signal detection wells are set;

3. After the tracer warning tape is installed, whether the beginning and end are isolated from the ground, and whether the warning tape in the signal detection well is fixed;

4. It can detect whether the diameter of the conductive metal wire in the warning tape meets the application requirements. If the diameter of the metal wire is too small, it is easy to be broken. If the diameter is too large, it will lead to an increase in the detection signal error. Therefore, the comprehensive effect diameter should be selected. The main problem of the detection signal is that the signal continuity is easily affected.

There are many reasons:

① It is possible that the wire inside the warning tape was broken due to the operation error during the construction, resulting in the detection short circuit

② The insulation and waterproof treatment of the warning tape are not qualified enough, resulting in the wire being affected by moisture and affecting the detection

③ If the diameter of the conductive wire is too large, the resistance will increase, the signal attenuation will increase, and the detection effect will be affected.

It is processed by anti-corrosion treatment, with good corrosion resistance, bright and eye-catching color. It will not corrode and fade after being laid underground for 50 years for a long time, meeting the requirements of unchanged long-term buried quality.

In order to protect the gas pipeline from man-made accidental damage in the future operation, the gas specification stipulates that a warning tape shall be laid at the place not less than 300 mm from the top of the gas pipeline, and the warning tape shall be marked with striking words.
