Abstract

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 maintenance are convenient.

Description

technical field [0001] The invention relates to the field of pipeline anticorrosion, in particular to the field of long-distance pipeline anticorrosion. Background technique [0002] At present, in my country's energy structure, fossil energy such as oil and natural gas still accounts for a relatively large proportion and is the main energy source in my country. However, the origin of oil and natural gas is often far away from the place where it is used, so long-distance transportation is required to use it. The most common way of transportation is pipeline transportation. [0003] Pipeline transportation is indeed the best way to transport natural gas and oil at present. It has the advantages of large transportation volume, safety, reliability, long-term use at one time, low cost, small loss during transportation, and small footprint. However, the main body of the transportation is Pipeline, pipeline is also the channel of transportation, so the condition of the pipeline di...
