    • Hydraulic flange connectors connect two flange components together, and hydraulic pressure applied to ports in connector holes of one of the flanges tension the flange studs and crush the gasket between the flange components. Each connector has a piston that disposes in the connector hole and can move therein when hydraulic pressure is applied through the port by a pump. A first stud connected to the piston extends beyond one open end of the hole for connection to a first nut, while a second stud connected to the piston extending beyond another open end of the to the second flange component for connection to a second nut. A retainer having seals threads in this other open end of the hole and seals between the hole and the second stud.
    • 液压法兰连接器将两个法兰部件连接在一起,并且施加到其中一个法兰的连接器孔中的端口的液压力拉紧法兰螺柱,并将垫圈压在凸缘部件之间。 每个连接器具有一个活塞,其配置在连接器孔中,并且当通过泵通过端口施加液压时可以移动。 连接到活塞的第一螺柱延伸超过孔的一个开口端,用于连接到第一螺母,而连接到活塞的第二螺柱延伸超过第二凸缘部件的另一开口端,用于连接到第二螺母。 具有在孔的另一个开口端中的密封螺纹的保持器,并且在孔和第二螺柱之间进行密封。
