Abstract: A wellhead pressure control fitting comprising a generally tubular Pressure Control Equipment (PCE) adapter configured to mate with pressure control equipment at a first adapter end, and with a receptacle inside a generally tubular pressure control assembly at a second adapter end. The pressure control assembly is configured to mate with a wellhead. Cooperating abutment surfaces form a high pressure seal when the second adapter end is compressively received into the receptacle. A plurality of cam locks on the exterior of the pressure control assembly rotate responsive to extension and retraction of the cam lock pistons. Cam lock rotation causes perimeter curvatures on the cam locks to bear down on corresponding curvatures on the second adapter end, which in turn compresses the second adapter end into the receptacle to form the seal. A locking ring may restrain the cam locks from rotation while the seal is enabled.

The first sealing portion has a first butting surface 51a having a tapered shape corresponding to a tapered shape of a first tapered inner circumferential surface 27a of the first flange, and a first projecting portion 51b. The first sealing portion is formed in a radially outer side of the gasket. The second sealing portion has a second butting surface 52a having a tapered shape corresponding to a tapered shape of a second tapered inner circumferential surface of the second flange, and a second projecting portion 52b.

Abstract: A flexible pipe joint has two annular elastomeric flex elements stacked in a co-axial fashion at an inner radius from a common center of rotation, and at least one elastomeric flex element disposed at an outer radius from the common center of rotation. The flex elements at the inner radius are coupled mechanically in series between the extension pipe and the housing of the flexible pipe joint, and the flex element at the outer radius is coupled mechanically in parallel with the series combination of the inner flex elements. The inner flex elements isolate the flex element at the outer radius from transport fluid, and the flex element at the outer radius reduces the axial compression of the inner flex elements. Thus, the inner flex elements may have a reduced radius and a different composition to handle a higher loading of heat and pressure.

Abstract: A double-ended flexible pipe joint has first and second extension pipes extending from opposite ends of an outer housing, and first and second primary annular elastomeric flex elements mounting the first and second extension pipes to the outer housing. An inner housing is disposed in the outer housing, and first and second secondary annular elastomeric flex elements disposed in the inner housing mount the first and second extension pipes to the inner housing. Tension upon the first and second extension pipes places each of the first and second primary flex elements and each of the first and second secondary flex elements in compression. The first and second secondary flex elements contain fluid pressure within the first and second extension pipes so that the first and second primary flex elements are not subjected to the fluid pressure within the extension pipes.

Abstract: A flexible joint has an extension mounted to a housing for relative angular displacement. Two or more annular elastomeric flex elements are stacked in a co-axial fashion and joined mechanically to mount the extension to the housing so that the flex elements react in parallel to angular and axial displacements of the extension with respect to the housing so that tensile load upon the extension places each of the flex elements in compression to split and share the tensile load among the flex elements in proportion to their relative axial stiffnesses. Therefore, for a given housing size or footprint, the overall load capacity is increased, and the lifetime of the flexible joint is increased for a given load capacity. The flex elements may have a common center of rotation, and the flex elements may be disposed either on the same side of the center of rotation or on opposite sides.

Abstract: The present invention provides a flexible hose easily converted to a rigid hose. The flexible-rigid bimodal hose comprises a plurality of adjacently engaged hollow members defining a tube having a first end, a second end, and an elongated hollow. A flexible tube as well as a cable pass through the hollow and extend therethrough. The cable acts as a means to apply tension on the hollow members. The hose has a flexible state in which each one of the hollow members is rotating in respect to neighboring hollow member and a rigid state in which the hollow members are forced together by the cable so that there is no relative movement between neighboring hollow members. An actuation means, which can be mechanically or hydraulically operated, is adapted to apply different tensile forces on the cable.

Abstract: A continuous flexible conduit is formed from like-configured components, each having a male joint member and a female joint member with a passageway extending therethrough. The female joint member is over-molded about a corresponding male joint member to form a substantially fluid-tight articulating joint. In a method of producing the flexible conduit, a single-shot molding process is used to form each like-configured component, with each newly formed component indexed within the single-shot mold so that the male joint member is within the female mold cavity for the formation of the next component. In an alternative embodiment, a continuous conduit is formed of two different sets of like configured components—one set having only female joint members and the other set having only male joint members. A two-shot molding process is described for continuous production of the flexible conduit using these two sets of components.
