The function of the pipeline warning tape is to serve as a warning, which is generally arranged 10-30 cm above the pipeline. When there is excavation construction, the warning tape is found to know that there is a pipeline below. The warning tape with metal wire is mainly used on non-metallic pipes, which is convenient for routine inspection, identification and detection of instruments. Next, let's take a look at the placement and function of the pipeline warning tape.

Warning tape shall be set at 0.3-0.5m above the top of buried gas pipeline to:

1. During excavation, if a warning tape is dug, it means that there is a gas pipeline 0.3-0.5m below, which serves as a warning and protection.

2. Tracer effect. When looking for buried gas pipeline, the pipeline can be found when the warning tape is found. It plays a tracing role.

3. The current warning is provided with a trace line, which can accurately locate the pipeline without excavation by using the testing instrument.

Common printing of underground warning tape

If there is cable under it, excavation is strictly prohibited; There is water supply pipeline under it, and excavation is strictly prohibited; It is forbidden to excavate the gas pipeline under it; There is oil pipeline under it, and excavation is strictly prohibited.
