  • Patent number: 10808871
    Abstract: A union joins male and female subs of two flowline components. The male sub includes a male end of one component, a retainer collar, and a union nut. An annular boss extends around a union face of the male end and provides a rearward-facing shoulder. The retainer collar is carried on the male end and has a forward-facing shoulder and a rearward-facing shoulder. The collar forward-facing shoulder bears on the male end rearward-facing shoulder. The female sub includes a threaded female end of the other component. The nut is carried on the male end around the collar and threads onto the female end. It also has a forward-facing shoulder which bears on the collar rearward-facing shoulder. The nut forward-facing shoulder and the collar rearward-facing shoulder are beveled. Thus, load from the nut is transmitted through the collar axially to the annular boss and radially inward to the male end.

    Abstract: A pipe joint structure is used to prevent a tube and pipe joint, especially fluororesin pipe joint from slipping off. The pipe joint comprises a joint body, a fixed ring and a union nut. A jig is used to expand the tube end to become a flared end consisting of a conical surface and a tubular surface, and finally connect it to the conical surface and tubular surface on top of the tube connecting portion of the joint body. When the union nut is fastened to the locking thread of the tube connecting portion, its interior recess portion will couple with the bulging surface of fixed ring to ensure it to stay in a concentric position, thereby allowing the tube wall of sealed surface to be compressed evenly and secured firmly on said pipe joint so to achieve a seal and prevent it from slipping off.

End-face seals minimize the sealing radius and therefore allow various fittings—including known ferrule fittings—to be used in high-pressure systems. End-face seals at such high pressure may require smooth surfaces. In order to reduce cost, an end-face preparation tool forges a dimple into the end face to mechanically deform and smooth the surface.

  • Patent number: 8366155
    Abstract: A coupler for use in sealing a joint between two pipes. The coupler is comprised primarily of two center sections and two end caps. The two center sections are engagable with one another and the two end caps are engagable with the center sections. Gasket rings create seals between the two center sections as well as between the two center sections and the cap rings. The center sections are dimensioned to create a volume of space within the coupler, thus permitting the coupler to accommodate offset joints. The gasket rings between the cap rings and the center sections can be longitudinally spaced apart, minimizing the angular deflection of the coupler with respect to the pipes when the pipe joint is offset. The center sections and end caps can be lockably engaged.

  • Publication number: 20120205304
    Abstract: A connector is used to connect a conduit to a threaded orifice of a fluidic component, such as a component of an apparatus for chromatography. The connector includes a flexible fitting, a deformable fitting, and a compression fitting. The flexible fitting fixes the position of the conduit with respect to the threaded orifice. The deformable fitting provides a fluid-tight seal between the fluidic conduit and the threaded orifice. The compression fitting includes an external-thread portion for attachment to the orifice, to urge the flexible fitting toward an outer surface of the fluidic conduit, and to urge the deformable fitting toward both the outer surface and the orifice, a cam portion in mechanical communication with the flexible fitting via a through-hole in the external thread portion, and a graspable portion in rotatable communication with the cam portion.

  • Patent number: 8205916
    Abstract: A metal ring gasket provides a high-pressure temperature tolerant metal-to-metal seal between subcomponents of a threaded union. The metal ring gasket is received in an annular cavity formed between mating surfaces of the subcomponents of the threaded union. The metal ring gasket is capable of maintaining a fluid seal even at very high temperatures resulting from direct exposure to fire. At high fluid pressures the metal ring gasket is energized because hoop stress induced by the fluid pressure forces the metal ring gasket into tighter contact with the subcomponents of the threaded union.

  • Publication number: 20120038150
    Abstract: A drive nut for a fitting includes an interior socket centered on a central axis and configured to receive at least a rearward portion of a conduit gripping member. The socket is defined by a radial drive surface positioned to engage the conduit gripping member during pull-up, a first longitudinal surface radially outward of said drive surface and a radially tapered second longitudinal surface between the drive surface and the first tapered longitudinal surface, wherein a conduit gripping device contact the second longitudinal surface upon an initial pull-up and each remake. This geometry facilitates a greater number of available remakes by reducing lost stroke, and can provide less stroke loss for fittings pulled up by torque.
