摘要
“十四五”期间我国长输管道仍将处于高速发展阶段,定期对管道进行维护和维修可减少管道事故发生的概率,管道应急抢修技术越来越受重视和关注。指出了我国管道应急抢修存在的问题,管道抢修技术水平参差不齐,高压管道封堵机具研发及应用存在差距,缺少管道应急抢修国家标准。为实现安全、高效管道抢修作业,保障管道安全运行,阐述了国内外管道行业在补板抢修、带压开孔封堵、堵漏夹具方面的技术现状,介绍了智能封堵、复合材料等新型管道抢修技术。结合我国长输管道应急抢修实践经验和应用情况,提出了管道应急抢修体系建设工作和研究建议,包括海底管道抢修、高温高压封堵密封性、管道断裂抢修和特殊环境下管道抢修专用机具的研发。
During the 14th Five-Year Plan period,China long-distance pipelines will still be in the stage of rapid development.Regular maintenance and repair of the pipelines can reduce the probability of pipeline accidents.Pipeline emergency repair technology has been paid more and more attention.The existing problems of pipeline emergency repair in China are pointed out:uneven technical level of pipeline emergency repair,backward research and application of high-pressure pipeline plugging equipment and lack of national standard of pipeline emergency repair.In order to realize safe and efficient pipeline repair and ensure the safe operation of pipeline,this paper expounds the current technical status of patch repair,hot tapping and plugging as well as plugging clamp in domestic and foreign pipeline industry,and introduces new pipeline repair technologies such as intelligent plugging and composite materials.Combined with the practical experience and application of emergency repair of long-distance pipelines in China,the construction work and research suggestions of pipeline emergency repair system are put forward,including submarine pipeline emergency repair,high-temperature and high-pressure plugging sealing,pipeline fracture repair and special equipment research and development for pipeline emergency repair in special environment.
