摘要:
天然气长输管道干线输送压力较高且往往无法停输，一旦与干线连接的法兰部位出现泄漏，在线堵漏很困难。通过对管道法兰连接部位出现的各类泄漏隐患原因进行分析，组建模拟试验系统，结合实际开展管道法兰在线治理技术的试验研究，提出了采用专用高压卡具、不停输开孔封堵和复合材料修复技术治理管道阀门法兰泄漏的技术方案。在实际应用过程中，需要针对法兰泄漏的不同情况，在确保作业安全的前提下选择一种经济有效的技术方案，是有效治理管道法兰泄漏的关键。
Abstract:
Generally, long-distance gas pipeline operated with high pressure will be not shut down unless necessary, and if the flange connected with gas truck line leaks, it will be very difficult to plug the leakage under pressure by online way. This paper analyzes different leakages dangers occurring in flanges of pipeline, establishes a simulation test system, and puts forward a technical approach to the repair of damaged flange with high-pressure clampls, stopple and composite material repair technology. In the practical application process, a cost-effective technical solution should be selected under the premise of ensuring operation safety according to different flange leakage situations, and this is the key for successful control of flange leakage of pipelines.
