Tracer line, also known as pipeline detectable wire, is convenient for construction and can be buried simultaneously. It is buried between the underground and pipeline, playing a role in detecting pipelines. It serves as an accurate positioning for pipelines during future excavation and repair, or informing three parties in advance to avoid unnecessary damage and causing major accidents. Tracer lines can be widely used for accurate detection of five types of transportation systems related to national economy and people's livelihood, such as various directly buried gas pipelines, oil pipelines, urban water supply and drainage pipelines, and other gas and liquid pipeline transportation systems. They play a significant role in protecting various complex urban pipeline network construction sites, road construction sites, traffic accident sites, and directly buried pipelines in construction sites and fields, Avoiding property and economic losses caused by accidental damage is an economical, effective, and simple tool for the safety protection of various directly buried pipelines and cables.
