Patent number: 10627028Abstract: A pipeline misalignment flange includes a socket member having a first smaller spherical internal surface, the socket member having a first face surrounding the first substantially spherical internal surface, the first face having a recessed channel. A retainer member includes a second larger spherical internal surface, the socket member and the retainer member being fastened together. A ball member includes a first smaller spherical external surface for engaging the socket member and a second larger spherical external surface for engaging the retainer member. The second larger spherical external surface includes an axially protruding portion with an undercut, the ball member being pivotable relative to the socket member such that the axially protruding portion of the second larger spherical external surface is received in the recessed channel.Type: GrantFiled: May 14, 2018Date of Patent: April 21, 2020Assignee: Freudenberg Oil & Gas, LLCInventors: John Stobbart, Michael Sheehan

Patent number: 8944472Abstract: An all metal ball and socket joint for connecting two misaligned conduits in fluid-tight communication utilizes a metal seal ring having a substantially conical bore which provides a relatively flush bore profile to fluid flowing through the seal ring. The cone angle of the conical bore is chosen in accordance with the maximum misalignment expected. The seal ring is attached to the nose of the ball member preferably by bolts. Seals are pressure energized by fluid flow. An annular o-ring groove and a pressure port can be provided to allow a back seal test to be carried out during installation.Type: GrantFiled: June 8, 2011Date of Patent: February 3, 2015Assignee: Vector International LimitedInventor: John Stobbart

Patent number: 8657145Abstract: A system for sealing an access port of a pressurized container or conduit comprises a metallic cap 10 having a sealing surface 20 which forms a seal with a corresponding sealing surface 16 of a metallic access port assembly 2, when the surfaces are pushed against each other by a clamping means 4 which is preferably separate from the cap. As shown the metal to metal sealing surfaces are frustro-conical in shape. The cap comprises a shoulder 26 which engages the rim of the access port if the cap is over tightened preventing deformation of the sealing surfaces. The cap may comprise a further frustro-conical sealing surface 40 which co acts with a corresponding surface 46 on an insert 6 which fits within and rests upon an internal shoulder 18 of the access port assembly 2 which may be welded onto a container.Type: GrantFiled: April 30, 2009Date of Patent: February 25, 2014Assignee: Vector International LimitedInventor: John Stobbart

Patent number: 5466018Abstract: A seal ring (4) and connection joint (1) for connecting and sealing conduits/pressure vessels (2, 3) and the like is disclosed. The seal ring comprises a sealing portion (5) having a pair of seal lips (6, 7) sloping radially outwardly to a web portion (8), the web portion extending radially outwardly to a spigot (9) having portions projecting transversely to the web. The thickness of the spigot in the radial direction (w) is substantially greater than the thickness of the web in the transverse direction (t), and the seal lips project transversely from the web by a distance (h) which is substantially greater than the thickness of the web in the transverse direction (t). This configuration provides improved seal characteristics. The joint (1) comprises the seal ring interposed at the interface between two conduit (or vessel) members (2, 3), the conduit or vessel members being provided with respective recesses (10, 11) arranged to receive the sealing lips and spigot of the seal ring.Type: GrantFiled: September 8, 1994Date of Patent: November 14, 1995Assignee: Techlok LimitedInventor: John Stobbart
