Long-distance pipeline anticorrosion device and method

The invention discloses a long-distance pipeline anticorrosion device and method. The device comprises a conveying pipeline, an anticorrosion layer, a protection layer, a pipe pier, an isolation plate, a rubber layer, a heat shrink pipe and two detectors. The anticorrosion method comprises the steps of pipeline treatment, anticorrosion layer spraying, protection layer arranging, pipeline arranging, pipeline joint arranging, detector arranging, monitoring and maintenance. According to the long-distance pipeline anticorrosion device and method, pipeline corrosion prevention is achieved mainly through anticorrosion coating spraying, pipe pier and joint of the conveying pipeline, the rubber layer and a heat shrink pipe protection pipeline isolation with an isolating plate and detector real-time monitoring; the reliability is higher, the anticorrosion performance is better, and the construction process is simple and convenient; and the pipeline environment can be monitored in real time, andpipeline inspection and
