US Patent:

6371527, Apr 16, 2002

Filed:

Nov 1, 2000

Appl. No.:

09/703575

Inventors:

Tep Ungchusri - Woodlands TX
Sergio A. Castillo - Spring TX

Assignee:

FMC Corporation - Chicago IL

International Classification:

F16L 2704

US Classification:

285276

Abstract:

The present invention is directed to a swivel joint for fluid conduits which comprises a central axis; a tubular male member having an outer annular surface, a first end and at least first and second outer annular grooves formed on the outer surface coaxial with the central axis; a tubular female member having an inner annular recess, an annular shoulder formed at an inner end of the recess and at least first and second inner annular grooves formed on the recess coaxial with the central axis; wherein the outer surface of the male member is adapted to be received in the recess of the female member such that the first end is disposed proximate the shoulder and each outer groove is aligned with a corresponding inner groove to thereby define at least first and second annular races; a plurality of balls disposed in each race to secure said male and female members together and to facilitate relative rotation of the male and female members about the central axis; wherein the radius of each race as measured from the central axis is greater than the radius of each adjacent race closer to the first end of the male member; and wherein the number of balls in each race is one more than the number of balls in each adjacent race closer to the first end.

Assignee:

FMC Corporation - Chicago IL

International Classification:

F16L 1902
F16L 2700

US Classification:

285374

Abstract:

A load segment assembly for use in pipe swivel joints or pipe connectors locks male and female hubs of a joint together while providing an axial bearing therebetween. The load assembly includes arcuate segments each having a dove-tail groove on the face of the convex side of the arcuate segment, requiring a flexible joining member to be threaded therethrough, providing maximum shear and bearing strength.

Filed:

Appl. No.:

8/742520

Inventors:

Sergio A. Castillo - Spring TX

Assignee:

FMC Corporation - Chicago IL

International Classification:

F16L 2704

US Classification:

285276

Abstract:

A fluid-carrying swivel joint has a stepped bearing race arrangement on interconnecting hubs having an improved bore seal capability. The stepped arrangement allows more ball bearings per adjacent race which allows equal distribution of hydrostatic end loading to each bearing race, thereby enabling maximum total end loading while minimizing load concentration on a particular bearing race section due to increased total ball and race contact area. A straight bore type seal is used to reduce surface area subject to axial pressure and to minimize rotational friction.

Sergio A. Castillo - Spring TX

Assignee:

FMC Corporation - Chicago IL

International Classification:

F16J 1512

US Classification:

2771675

Abstract:

A bore seal assembly for sealing between adjoining tubular members having a seal pocket formed in the adjacent ends thereof which comprises a cylindrical seal sleeve having a bore and two radially outwardly extending sealing lips for engaging the seal pocket, a cylindrical finger spring mounted within the bore of the seal sleeve and having an annular central section and a plurality of fingers extending axially outwardly therefrom for urging the sealing lips against the seal pocket, and a cylindrical wear sleeve having a curvilinear outer diameter for supporting the fingers and transferring the contact point between the fingers and the wear sleeve toward the ends of the fingers to thereby increase the stiffness of the fingers and maintain a spring force sufficient to overcome the force caused by contraction of the seal sleeve in low temperatures.

Assignee:

FMC Corporation - Chicago IL

International Classification:

F16L 2100

US Classification:

277603

Abstract:

A bore seal assembly for sealing between first and second adjoining tubular members which comprises a cylindrical seal sleeve having a bore and two radially outwardly extending sealing lips for engaging a seal pocket formed in the adjoining ends of the first and second tubular members, a cylindrical wear sleeve mounted within the bore for supporting the seal sleeve within the seal pocket, and an elongated erosion sleeve extending longitudinally from the wear sleeve into at least the first tubular member, whereby the erosion sleeve protects the first tubular member against erosion.
