摘要：

随着柔性软管的国产化,国内越来越多的油田采用柔性软管输送油品介质.在软管管段之间的连接接头属于刚性结构,而管体属于柔性结构,在接头与管体之间存在刚度的突变,在受到较大弯矩作用时,柔性管体将被破坏,因此需要在管体和接头之间设置弯曲加强器,起到刚度过渡的作用,保护管体.在进行弯曲加强器的设计时,参考国外实例,选用聚氨酯弹性体作为结构主材,并配有连接钢件.结合项目实例,重点介绍了静态柔性软管弯曲加强器的结构形式.该结构可在软管过驳和安装时保护管体.

Abstract:

With the localization of flexible pipes, more and more oil fields use the flexible pipe as conveying flowline. End fitting whose function is to connect the pipe sections is a rigid structure, while the pipe body is flexible, there is a stiffness mutation between them. When subjected to a large bending moment, the pipe body will be damaged, so it is necessary to set a bend stiffener between the pipe and the end fitting. To design a bend stiffener, an applicable material should be selected. We use polyurethane elastomer as the principal material for the bend stiffener. Besides, some steel interface structures are requisite. We mainly introduce a static bend stiffener design. It can protect the pipe during installation and overboarding.

Key words: subsea pipeline, flexible pipe, end fitting, bend stiffener, polyurethane elastomer
