A high-thermal conductivity grout composition is provided. The composition includes a grout mixture including a cementitious material, a retarder, and a high-thermal k material that advantageously can form a pumpable slurry upon admixture with water. The retarder is present in an amount effective that delays setting of the grout mixture at a target location having a geostatic target temperature of at least 300° F. for at least two hours. The high-thermal k material is present in an amount effective such that the grout mixture has, upon setting at the target location, a thermal conductivity of at least 1 W/m° K.

High thermal coefficient grout compositions and methods therefor

A valve gate assembly with a eutectic implement configured to degrade in response to a force imparted along a non-parallel load path. The unique architecture employed for various embodiments ensures a non-parallel load path is employed in triggering the shift in position for a valve gate. This enhances the integrity of the eutectic implements such that a wider variety of valve gate assembly dimensions may be utilized. This, in turn, allows for such assemblies to be utilized with larger production line volumes without compromise to safety measures afforded by such safety valves.

A technique facilitates rapid transitioning of a valve, e.g. a gate valve. According to an embodiment, a system comprises a valve actuator constructed for coupling with a valve to actuate the valve between closed and open positions. Hydraulic actuation fluid may be supplied to the valve actuator under pressure via a hydraulic supply system to enable selective shifting of the valve actuator, and thus the valve, from a closed position to an open position. The system also comprises a dump tank coupled to the valve actuator in a manner to receive hydraulic fluid. In a rapid valve actuation operation, e.g. closing operation, the dump tank receives hydraulic fluid from the valve actuator rather than returning the hydraulic fluid to the hydraulic supply system. This, in turn, enables rapid shifting of the valve actuator and thus rapid shifting of the valve.

Quick closing valve system and methodology

A system includes a first body of a fluid-handling component and a second body of a fluid-handling component. The system also includes a fastener configured to couple the first body to the second body, and an annular sleeve configured to surround a portion of the fastener that is positioned at an interface between the first body and the second body when the first body and the second body are coupled to one another.
