[0003] In modern industry and urban construction, pipeline systems play a vital role in transporting various fluids, including water, natural gas, oil, and chemicals. In order to ensure the stable transmission of the medium inside the pipeline and reduce heat loss, the outer layer of the pipeline is usually wrapped with one or more layers of insulation material. However, during long-term operation, the pipeline may be damaged due to internal and external factors, which not only affects the transmission efficiency but also may cause safety problems. Once the pipeline is damaged, it needs to be repaired in time, and the first step of the repair is often to remove the insulation layer around the damaged part so that direct access to the pipeline body can be made for repair.
