适用于浅海小口径复合软管的接头形式研究

Research for End Fitting of Small-bore Composite Flexible Pipes in Shallow Water

设计了一种适用于软管结构的接头形式,在一定压力作用下保证软管的强度和密封性,同时能够释放金属铠装层中累积的渗透气体,成功实现复合软管的连接和保护。因其在动力特性、地形适应性、抗腐蚀性、安装等多方面的优势,越来越多的油田开发考虑采用软管来代替钢管,具有很大的发展前景。

Design a type of the flexible pipe end fitting, which can have enough strength and leak tightness under certain pressure and can release the accumulated gas in the armor lay- ers, and this type of end fitting have successfully achieved the connection and protection re- quest of the flexible pipes. A major advantage of using the flexible pipes is their ability to work under extreme dynamic conditions and their relatively seabed adaptability and chemical compatibility properties and installation convenience compared with rigid carbon steel pipes.
