Abstract: A fluid coupling includes various features. One feature is a disconnect tool that may expand a lock ring from engagement with a lock shoulder to permit the male half and female half to be separated. Another feature is to utilize geometry and structure whereby a leak would occur to indicate the condition of wear within the coupling while the coupling halves remain mechanically coupled. A further feature is to provide connection verification structure to assure that a complete connection of the male and female halves has been made. A still further feature is to provide an anti-rotational sleeve which would selectively prevent and permit relative rotation between the male half and the female half.

Abstract translation: 流体联轴器包括各种特征。 一个特征是断开工具，其可以使锁定环与锁定肩部的接合膨胀，以允许雄性半部和雌性半部分离。 另一个特征是利用几何形状和结构，由此发生泄漏以指示联接器内的磨损状况，同时联轴器半部保持机械联接。 另一个特征是提供连接验证结构，以确保已经进行了雄和半的完全连接。 另一个特征是提供一种防旋转套筒，其可选择性地防止并允许阳半部和阴半部之间的相对旋转。

Abstract: A coupling assembly for connecting two members is provided that includes a first nullmalenull member and a second nullfemalenull member. The first member includes a release sleeve moveably mounted thereon having a rigid release portion and a flexible sealing portion. The second member is integrated into an apparatus, such as a pump, and includes a duct therethrough for receiving the first member. Upon connection of the first and second members, the flexible sealing portion sealingly engages a recessed seat portion of the second member to substantially inhibit the ingression of contaminates into the duct when the first and second members are connected. The foregoing coupling assembly is advantageous because it allows the second member to be formed directly into an apparatus. In other embodiments, the coupling assembly provides an improved release sleeve that releases the male member from both a conventional female member and an integral female member.

Abstract: A fitting assembly includes an indicator assembly that provides a visual indication of torque value to verify when the desired operational torque value is achieved. The fitting assembly includes a nut, and a visual indicator assembly positioned on the nut which has a plurality of visual indicators that provide a visual indication of a torque level being applied. A sleeve is attached to the nut and includes a window through which a portion of the visual indicators is visible based on the torque level being applied. A resilient member couples the sleeve to the nut. As the nut is rotated to apply torque to the nut, the resilient member biases the sleeve in a fixed position and the nut rotates relative to the sleeve, whereby the visual indicator assembly rotates relative to the sleeve to alter which portion of the visual indicator assembly is visible through the window to provide a visual indication of when the operational torque level is being applied. The fitting assembly includes a positive locking feature that interacts with a serrated portion of a nipple fluid connection to positively lock a position of the nut to prevent nut loosening.

Abstract: An apparatus for connecting two pipes in fluid communication is provided. The apparatus comprises a connector body having opposing open ends, each open end configured for receiving a free end of a pipe; a mechanical interlock arrangement, for preventing or limiting axial movement of the connector body relative to a free end of a pipe when the free end of the pipe is received in an open end of the connector body; and a mechanical seal arrangement for providing a metal-to-metal seal between a pipe inserted into one of said open ends and the connector body.

Abstract: A method and apparatus for providing an expandable threaded connection between segments of expandable tubulars. Threaded connections are machined into pre-expanded ends of tubulars. Once the threaded connections are machined into the pre-expanded ends, two joints of tubulars are connected using the threads, thus creating a pre-expanded threaded connection. After a tubular string is made up and lowered into a wellbore, the entire length of the string is expanded using known methods for expanding tubulars. During the downhole expansion operation, the pre-expanded threaded connections experience minimal expansion. The minimal downhole expansion of the pre-expanded threaded connections allows the threaded connections to maintain their sealing ability and coupling strength.

Abstract: A tube fitting capable of absorbing vibration and shock resulting from a high pressure fluid passing through the tube fitting while it is used includes a connection head, a connection nipple, and an intermediate connection member. The connection head and the connection nipple are provided with an annular collar projecting from an end surface of the connection head and the connection nipple. The connection head, the connection nipple and the intermediate connection member are joined by inserting the annular collars into both ends of the intermediate connection member.
