Abstract: Apparatus and method contemplating a high pressure fluid end assembly having a body defining a body bore and defining a recess in the body intersecting the body bore. A closure is joined to the body and forms a sealing surface. A seal is mounted to the body in the recess and configured to extend from the recess beyond the body bore to seal against the sealing surface formed by the closure.

Abstract: A high pressure swivel joint used in pipe assemblies transferring high pressure fluid. The swivel joint comprises a first pipe section and a sleeve-like second pipe section. The first pipe section is inserted into the second pipe section and the sections are relatively rotatable. A wear ring is positioned within a recess formed in the inner wall of the first pipe section. A second wear ring is positioned within a recess formed in the inner wall of the second pipe section.

Abstract: A closure for a fluid end having a middle sealing section which engages a seal. The sealing section either has a larger outer diameter than adjacent sections or contacts a bore with a smaller inner diameter than adjacent sections. In either case, the clearance formed on either side of the sealing section reduces friction and allows the closure to be rocked back and forth to insert and remove the closure from the fluid end bore.

Abstract: Apparatus and method contemplating a high pressure fluid end assembly having a body defining a body bore and defining a groove in the body intersecting the body bore. A closure is joined to the body and forms a sealing surface. A seal is mounted to the body in the groove and configured to extend from the groove beyond the body bore to seal against the sealing surface formed by the closure.

Abstract: A fluid end comprising a plurality of fluid end sections positioned in a side-by-side relationship. Each fluid end section is releasably attached to a connect plate. Each connect plate is attached to a power source using a plurality of stay rods. Each fluid end section comprises a housing in fluid communication with a pair of intake manifolds and a discharge conduit. A fluid routing plug is installed within each housing and is configured to route fluid throughout the housing. A plunger is installed within stuffing box attached to each housing. A number of features, including the location of seals within bore walls and carbide inserts within valve guides, aid in reducing or transferring wear.
