【摘要】：我国石油资源开采急需大量管道,非粘结柔性管道以其柔性好的优势得到广泛应用。接头是非粘结柔性管道终端的重要连接装置,起到连接、密封和排气的作用。接头由上部连接法兰、接头颈部、接头主体组成,而接头主体由连接系统、密封系统和排气系统组成。接头是柔性管道系统中最为薄弱的环节,在功能与环境荷载的作用下最容易发生失效,而接头的关键设计分析技术长期为国外垄断,自主研发接头关键技术具有重大意义。本文首先对非粘结柔性管道接头在国内外的应用与研究成果进行调研,总结出接头的失效模式,提出了基于控制失效模式的接头设计方法及设计流程。针对失效模式中最为严重的密封问题,提出了基于ABAQUS软件分析的接头密封结构设计方法,介绍了几类参数对接头密封结构的影响。针对基于软件进行设计分析中的不确定性,提出了接头密封试验方案。最终以接头863工程项目为例,结合前面几章的结论,给出接头设计方案。本文依托非粘结柔性管道接头“十二五”863课题开展,对于非粘结柔性管道接头装备的国产化具有重大意义。
[Abstract]:A large number of pipelines are urgently needed for the exploitation of petroleum resources in China, and the non cohesive flexible pipes are widely used because of their good flexibility. The joint is an important connecting device for the Unbonded flexible pipe terminal, which plays the role of connection, sealing and exhaust. The joint consists of the upper connecting flange, the neck of the joint and the joint body, and the joint body consists of the connection system, the sealing system and the exhaust system. Joint is the weakest link in flexible pipeline system. It is most likely to fail under the action of function and environmental load. The key design and analysis technology of joints is monopolized abroad for a long time, and the key technology of independent research and development is significant.
