摘要： A bore seal assembly for sealing between first and second adjoining tubular members which comprises a cylindrical seal sleeve having a bore and two radially outwardly extending sealing lips for engaging a seal pocket formed in the adjoining ends of the first and second tubular members, a cylindrical wear sleeve mounted within the bore for supporting the seal sleeve within the seal pocket, and an elongated erosion sleeve extending longitudinally from the wear sleeve into at least the first tubular member, whereby the erosion sleeve protects the first tubular member against erosion.

摘要： A bore seal assembly for sealing between adjoining tubular members having a seal pocket formed in the adjacent ends thereof which comprises a cylindrical seal sleeve having a bore and two radially outwardly extending sealing lips for engaging the seal pocket, a cylindrical finger spring mounted within the bore of the seal sleeve and having an annular central section and a plurality of fingers extending axially outwardly therefrom for urging the sealing lips against the seal pocket, and a cylindrical wear sleeve having a curvilinear outer diameter for supporting the fingers and transferring the contact point between the fingers and the wear sleeve toward the ends of the fingers to thereby increase the stiffness of the fingers and maintain a spring force sufficient to overcome the force caused by contraction of the seal sleeve in low temperatures.
摘要翻译： 一种用于密封相邻管状构件的孔密封组件，其具有在其相邻端部中形成的密封袋，其包括圆柱形密封套筒，其具有孔和用于接合密封袋的两个径向向外延伸的密封唇，安装在孔内的圆柱形指状弹簧 并且具有环形中心部分和从其向外轴向延伸的多个指状件，以将密封唇推压到密封袋上;以及圆柱形磨损套筒，其具有用于支撑指状物并将接触点传递到第二部分之间的接触点 手指和磨损套筒朝向手指的端部，从而增加指状物的刚度并且保持足够的弹簧力以克服由于密封套筒在低温下的收缩而引起的力。

摘要： A load segment assembly for use in pipe swivel joints or pipe connectors locks male and female hubs of a joint together while providing an axial bearing therebetween. The load assembly includes arcuate segments each having a dove-tail groove on the face of the convex side of the arcuate segment, requiring a flexible joining member to be threaded therethrough, providing maximum shear and bearing strength.
摘要翻译： 用于管道旋转接头或管道连接器的负载段组件将接头的公和母毂锁定在一起，同时在其间提供轴向轴承。 负载组件包括弧形段，每个弧形段在弓形段的凸面的表面上具有鸽尾槽，需要使柔性接合构件穿过其中，从而提供最大的剪切和承载强度。
