  • Patent number: 9539670
    Abstract: An end-to-end tubular joint includes first locking pieces cut from the first tube and second locking pieces cut from the second tube, where the cuts have radial cut faces on the axially aligned cuts. The first and second locking pieces are interlocked with lateral extensions of the respective locking pieces bearing against one another and the radial cut surfaces distributed circumferentially around the joint so as to constrain relative movement between the parts. The first locking pieces are welded to the first tube and the second locking pieces are welded to the second tube to form a tube joint. An alternative forms cutouts in the first tube and fits locking pieces into the cutouts that are welded to a second member, such as a second tube or cylinder that fits into the first tube so as to form the tube joint.

  • Patent number: 9435469
    Abstract: A mechanical coupling for joining pipe elements has segments joined end to end, each segment having a pocket of varying depth for receiving a ring gasket. The varying depth of the pocket is used to control the distortion of the ring gasket between a round shape and a non-round shape when the segments are arranged in spaced apart relation around the ring gasket, the spacing between the segments being sufficient to permit insertion of the pipe elements without disassembly of the coupling. Notches in the projections which engage the pipe elements facilitate insertion of pipe elements and provide for a compact coupling design.

  • Patent number: 9212771
    Abstract: An swage fitted end connector for high pressure large diameter reinforced flexible rubber hose utilizing sine-wave locking of the reinforcement and particularly suited to the petrochemical and drilling industries. Two embodiments of the connector for use with wire reinforced thin internal tube hose are disclosed: one with a diameter of 3-inches and for burst pressures up to 20,000 psi and the other for a diameter of 5-inches and for burst pressures up to 18,000 psi. All of the connectors will withstand the rated burst pressure of the hose without pumping off or leaking thus any hose that utilizes the device will fail before the connector pops off the hose. The connectors are designed to meet or exceed the new API temperature ranges and new API flexible specification levels which became effective in October 2006.

  • Patent number: 9134283
    Abstract: A plug unit and system for connecting capillary tubes, especially for high-performance liquid chromatography, with a plug capillary tube projecting through a hole of a plug housing, which is detachably connectable to a bushing unit. The plug capillary tube front end projects into a capillary tube receptacle in the bushing unit with its end face essentially aligned opposite a front end of a bushing capillary tube or a bushing capillary passage opening of the bushing unit, the end face of which is butted against. The plug housing applies a force, with its end face facing the plug capillary tube end, directly or indirectly on an annular sealing element surrounding the plug capillary tube in the region of the front end of the plug capillary tube such that the front end of the plug capillary tube is sealed through deformation of the sealing element against the capillary tube receptacle opening.
