Nowadays, the maintenance of complicated underground pipelines has become a big problem. Today, we are going to learn about the three key points for the purchase of underground warning tape!
1. Look at the material
Most of the buried pressure pipes are PE pipes, which are widely used in gas, water and other infrastructure construction. In order to protect these underground pipelines, reduce the chance of being accidentally cut during construction and excavation, and avoid serious consequences such as gas leakage, communication interruption, and even personal injury, buried warning tapes came into being.
The Standard for Urban Gas Signs currently implemented in China requires that the installation of medium and low pressure natural gas pipelines must be close to the pipeline location, and the tracers that can be detected must be buried, so as to facilitate the construction party to detect and locate the pipeline. The protective plate made of PE should be laid at 200-300 mm above the pipeline to avoid damage to the pipeline during excavation of excavation equipment.
Therefore, when purchasing the underground warning tape, the material is one of the key points that cannot be ignored. The underground warning tape is made of PE pipe material, which is often used to produce and make pipes. It is hard, acid and alkali resistant, and has a long service life. It will not deteriorate even if it is buried in wet soil for a long time.

2. See thickness
The impact resistance of a underground warning tape depends not only on the material, but also on the thickness of the plate. In order to reduce the production cost, some small manufacturers made a big deal in the thickness of the plates, and the thickness of the buried warning tapes produced was not up to the standard, which greatly affected the safety of the buried warning tapes.
The thickness and specification of the underground warning tape shall be improved to ensure the safety of the product. For example, the material density shall reach 0.9/cm3, the dimensional stability shall be less than 35%, and the overall thickness shall be controlled at about 3-5 mm, which is enough to ensure that the underground warning tape has better impact resistance and can form sufficient protection for the pipeline below.
3. Look at the printing quality
The underground warning tape not only needs to be installed with metal trace lines, but also should be printed with striking patterns and words on the surface to remind the construction unit to be careful and avoid construction risks as much as possible. As the underground warning tape is buried in the damp and hot ground for a long time, once the printing quality is not up to standard, it will bring unpredictable potential safety hazards to the construction.
The safety of underground warning tape has been greatly improved. Some auxiliary materials have been added to improve the overall toughness and aging resistance. High temperature film covering technology is used for the surface printing content, which can ensure that the printed patterns and characters can remain bright and eye-catching for a long time, and are not easy to fall off and fade, affecting the warning.
The underground warning tape looks ordinary, but it is a crucial line of defense for the safety of the underground pipe network. If you need to buy a safe and reliable underground warning tape, you can choose according to the above three key points.
