摘要： A wellhead seal assembly forms a metal-to-metal seal between inner and outer wellhead members. A metal seal ring has inner and outer walls separated by a slot. A lock ring has grooves for locking the inner wellhead member to the outer wellhead member during installation. An energizing ring has a C-ring captured on its inner surface. When the energizing ring is moved further into the slot, the C-ring is forced from its pocket and engages the surface of the inner wellhead member, locking the seal assembly to the inner wellhead member.

摘要： A wellhead seal assembly forms a metal-to-metal seal between the inner and outer wellhead members. A metal seal ring has inner and outer conical walls separated by a tapered slot. An energizing ring has inner and outer annular members that are separated by an annular cavity. When the energizing ring is moved further into the slot, the cavity width decreases but remains to provide a preloaded radial force to the seal ring.

摘要： A coating for use in protecting surfaces susceptible to environmental degradation. The coating may be applied to metallic surfaces for providing a barrier against elements and/or ambient conditions that would otherwise degrade the surface material. The coating includes multiple layers, where a thermoplastic polymer is included, wholly or partly, within one or more of the layers. Example applications of the coating are for protecting valve seat seals and valve stem seals of a valve assembly used in conjunction with handling of fluids produced from a subterranean formation.

摘要： A technique is provided for detecting the surface profile of a seat pocket of a gate valve. An inspection tool is used to detect data at a plurality of points around the bore of the valve. The inspection tool has a sensor that is moveable between a retracted position and an extended position. The inspection tool is disposed within a valve body cavity with the sensor in the retracted position. The sensor of the inspection tool is then extended outward so that it is located within the portion of the bore of the valve having the surface profile to be detected. The sensor is rotated so that the sensor may obtain surface profile data at a plurality of points around the seat pocket of the valve body. The sensor of the inspection tool is connected to a processor-based device, such as a computer. The processor-based device processes the data from the sensor and provides it to a user in a form that is recognizable to the user.

摘要： An enclosure thermal shield (10) has a thermally insulated open container (12), a thermally insulated closure member (14), a thermally conductive liner (16) along the container's inner surface and along the inner surface of the closure member (14) forming a thermal circuit when the closure member (14) closes the container (12), and a heat reservoir (18) in thermal contact with the thermal circuit. The heat reservoir (18) can be placed within the container (12) or incorporated into the closure member (14). If incorporated into the closure member (14), the heat reservoir (18) can be placed in direct thermal contact with the thermal circuit or connected to the thermal circuit via a thermal conduit (28). The thermal shield (10) can further comprise a layer (26) of insulating material lining the interior surface of the conductive liner (16). Heat pipes can also be employed as a part of the thermal circuit.

摘要： An advanced thermal container has a thermally insulated open receptacle, a thermally insulated closure member, a data monitoring system incorporated into the container that can send and receive information via wireless communication, and a sealing system to minimize heat transfer and air exchange between the interior and exterior of the container. Hard plastic casing enclosing foam-encased vacuum insulation panels is used to construct the insulated receptacle and closure member. The closure member and receptacle each have an elongated portion with shoulders above and below the elongated portion. When the container is closed, a lower seal and an upper seal are compressed between the mating lower and upper shoulders, respectively. The onboard data monitoring system records important parameters concerning the internal and external environments of the container, particularly temperature information, as well as other significant events such as the number of times the container was opened during transit.
