深水法兰连接机具螺栓预紧方法及装置研究

随着陆地和浅水油气资源的日益枯竭,急须开发深水油气资源以满足国民经济发展对能源的需求。法兰螺栓连接是深水管道连接的常用方法,也是深水管道回接必须攻克的难点。深水法兰连接机具是应用于深水管道法兰连接的一种专用设备,确定深水法兰连接机具的螺栓预紧方法对开发设计深水法兰连接机具具有重要意义,通过对比几种常用的螺栓预紧方法,确定了适用于深水的螺栓预紧方法,并设计了一种深水工作的螺栓预紧装置。该研究成果对机具的进一步开发,促进我国深水作业设备发展和提高我国深水管道连接技术具有一定意义。

Research on Method of Bolt Tightening and Bolt Tightening Equipment of the Deep Water Flange Connection Tool

Along with the wearing out of petroleum resource,petroleum resource of deep water must be exploited to improve nation economy development.The one of the methods of the deep water pipeline connection is the flange connection,but it is a difficult problem must be conquered.The deep water pipeline flange connection tool is a kind of special equipment to connect the deep water pipeline,to determine the method of the bolt tightening is important for developing the deep water pipeline flange connection tool.Through comparing the some methods of the bolt tightening,a method of the deep water bolt tightening is determined,and a set of the bolt tightening equipment is designed.The method and the equipment could promote the development of the deep sea technology and improve deep sea pipe flange connecting technology.
