A sealing profile protector for a subsea hydrocarbon production or processing system component includes a body having an contact surface which is configured to engage a sealing profile on the component. When the sealing profile protector is installed, the contact surface displaces seawater from the sealing profile. In this manner, contaminants are inhibited from forming on the sealing surface after the sealing profile protector is installed.

These fixtures aid in installing, sealing and securing pipe. Specifically, the invention aids in mating bell & spigot joints and securely capping open pipe ends of standard polyvinyl chloride (PVC), polyethylene (PE), and acrylonitrile-butadiene-styrene (ABS) pipe products as well as non-plastic piping by enabling equalized full circumference pressure on pipe ends to nudge, seal and/or secure pipe ends during installation or decommissioning.

A coupling may be configured to receive and secure an insertion end of a conduit. An outer surface of the insertion end of the conduit may be smooth and free of grooves, flanges and beads. A first member of the coupling may define a first passageway. A second member of the coupling may define a second passageway. The first member may be in engagement with the second member. A gripping ring having an inner edge defining a series of teeth may be disposed within the second member. A support ring and O-ring may also be disposed within the second member.

An apparatus for hydrostatic testing of items containing flanged openings and which items require periodic pressure testing, such as flanged pipe sections, flanged pipelines, flanged hose assemblies, as well as other flanged equipment requiring periodic pressure testing. The apparatus is clamp-like and is comprised of multiple circular plates that are designed and arranged to hold a blind flange against the flange of the item to be tested. One of the circular plates contains a circular cavity into which the blind flange can be stored when the apparatus is not in use.

A service port cap fits over the nipple (free end), annular flange and groove of a service port. An annular concavity (groove) in the interior wall of the cap receives the outwardly projecting annular flange of the service port. A resilient gasket disposed in the interior top of the cap is configured to plug the free end of the service port, when the cap is installed. Slots in the cap body define legs that can deflect outwardly and then return to an undeflected position when a deflecting force is removed. A locking ring, which includes an annular band that surrounds a portion of the cap body, is movable longitudinally between an unlocked position and a locked position in which the band surrounds and prevents outward deflection of the legs.

This invention relates to a fluid sealing device comprising a sealing member comprising a first surface and an opposite second surface. A first region of the first surface for forming a first seal about an aperture of a process component containing a fluid, and an inner region of the first surface to be exposed to the fluid via the process component aperture. A restraining member providing a support surface facing the second surface, a perimeter portion of the restraining member interfacing with a first region of the second surface, the first regions of the first and second surfaces corresponding with a first region of the sealing member. An inner region of the second surface spaced from the support surface to form a cavity between the inner region of the second surface and the supporting surface at least in an unpressurised condition. The inner regions of the first and second surfaces corresponding with an inner region of the sealing member, the inner region of the sealing member moveable towards and away from the support surface under action of a pressure of the fluid on the inner region of the first surface to provide an indication of the pressure.

A connector includes a connecting body with a fluid passage at least part way therethrough, and a seal is provided with an outer portion of a fluid tube. A cartridge proximate to the connecting body has a hollow portion therethrough. A grab part has at least one tooth to retain the fluid tube and is between the cartridge and the seal. A demount part within the hollow portion moves the teeth to allow release of the fluid tube. A latch is located on one of the connecting body or a sleeve covering at least part of the cartridge or the connecting body. A mating catch is located on the other of the sleeve or the connecting body, and engagement of the latch with the catch connects the sleeve to the connecting body and helps restrain cartridge movement.

A female coupling component for a cam and groove coupling, consisting of a chamber mounted to or built into the exterior of the female coupling component, containing a latching member to be used as a safety lock when used in conjunction with a male coupling component. The latching member will interlock with a radial groove on a male coupling component. To unlock the female coupling component, an intentional movement including pushing, twisting, and/or pulling, etc. of the latching member is applied such a way as to allow the male component to be inserted or removed. The female cam and groove coupling will work on any like-sized male coupling component (i.e., 3″ female to 3″ male) without any modifications necessary to the male coupling required.

An end cap for sealing an end of an existing pipe comprising a cylindrical cap member, the cylindrical cap member comprising an open end and a closed end, a clamp coupled to a band, a band track present along an exterior of the cylindrical cap member, the band encompassing the band track and one or more ribs present on an interior of the cylindrical cap member opposite to the band track. A method of using the end cap to seal an end of an existing pipe, comprising unlocking the clamp, inserting the end cap over the end of the existing pipe and locking the clamp.
