随着海洋石油开采的不断深入,应用管道无焊缝连接技术,在海底连接管道时,不需要干式焊接舱,直接操作,具有速度快、方便安装和安全可靠等特点.通过综合考虑管道受内压和外压的因素,研制了1套结构简单、使用方便的无焊缝机械连接方式的设计方案,完成了相应零件的三维设计,管道机械结构的组装,并对管道受力做了有限元分析,对螺栓和管道截面做了相应的强度校核.所设计的机械式连接器包括外筒、楔形结构、密封圈等机构.%With the rapid development of undersea-pipeline exploitation, the pipeline none-welding connected technology can have no use for dry welding cabin, direct manipulation, which are not only fast and convenient, but also safe. Considering the inner and outer press, we have come up with a mechanical none-welding pipe laying, connection device, which is simple in structure, convenient to handle, and low in cost. What's more, we have finished the three-dimensional design of the device, the install of the pipeline structure, the finite element analysis, the strength check of the bolt and pipeline section. Our design of the mechanical connector involves the outer tube, wedge-shaped structure, and the seal ring.
