A system for remotely opening and closing a process equipment bolt flange joint may include a hydraulic cylinder actuator assembly for attaching to the flanges of a bolt flange joint to open and close the joint by operation of a remote hydraulic pump. More than one actuator assembly may be evenly spaced around the flange joint, to ensure even distribution of force around the joint. The system may have an accumulator for receiving hydraulic fluid expelled from the hydraulic cylinder during extension and to force hydraulic fluid back into the cylinder to close the flange joint upon pressure release at the pump. A drop trigger may be used to release hydraulic pressure at the pump for emergencies. The system may include a video camera for viewing the joint on a display. The components may be stored and transported on a mobile cart. A method of use is also disclosed.

A self-installing connector for a liquid cooling system of a datacenter component rack system. A datacenter component rack may include manifolds for conveying coolant to or from one or more datacenter electronic components for liquid cooling components of the datacenter electronic component. The self-installing connector provides a fluid connection between the manifold and a liquid cooling system of a datacenter electronic component. The self-installing connector may puncture the manifold at the time the datacenter electronic component is installed. The self-installing connector may form an opening in the manifold and secure one end of the self-installing connector into the opening upon installation of the datacenter electronic component into the datacenter component rack. The self-installing connector can separate at a dripless quick-disconnect coupling for datacenter electronic component maintenance.

Coaxial fluid elements that utilize fluid pressure to aid in creating a sealed conveyance of two separate pressurized fluid streams. A coaxial fluid fitting provides a fluid-pressure assisted seal on a coaxial fluid transmission element. Coaxial fluid transmission elements allow two separate fluid flows within the same transmission element: one fluid flow through an interior core region, and a second fluid flow through an exterior annulus region. The fluid flows are separated by an internal wall, fully contained by an external wall, with structural members connecting the two walls. The fluid-pressure assisted coaxial fluid fitting accepts a coaxial fluid transmission element, providing seals between the two fluid flows as well as to the surrounding environment. The interior seal is fortified by situating a higher pressure fluid in the exterior annulus region, providing an inward sealing force without the use of a mechanical sealing aid. This enables transmission systems of pressurized fluids that are smaller in size and contain fewer points of failure, compared to standard systems with single fluid stream transmission elements and fluid transmission systems containing other multi-lumen transmission elements.

Hose has a body (3) and a mouthpiece (1) connected with the body (3). The mouthpiece (1) is slidably placed against the body (3); it is designed for mounting of the end of the hose and it has a thickening (2). The ending has a circumferential stop (4) placed in the axis of the mouthpiece (1), whereby the stop (4) has on its circumference a touch surface which is oriented inside, against the thickening (2) on the mouthpiece (1). The mouthpiece (1) can be sealed by sealing ring (7) against the body (3), whereby the ring (7) is placed in the sealing zone (9), or the mouthpiece (1) can be connected with the body (3) by a flexible bellow. During the movement of the mouthpiece (1) outside the touch surface of the stop (4) and the outer surface of the hose in the zone with the thickening (2) draw closer and the hose is held on the mouthpiece (1) by the underpressure between the surface of the stop (4) and the thickening (2). The increasing pressure in the hose increases the underpressure of the hose on the mouthpiece (1 ) which increases the sealing effect of the joint.

A conduit seal assembly includes an outer conduit having a first end with a first opening and a second end, opposite the first end, with a second opening. A first seal is positioned in the first opening for resisting a first temperature, and a second seal is positioned in the second opening for resisting a second temperature less than the first temperature. The first and second seals define a cavity and provide an air-tight seal of the cavity, and the assembly includes a monitoring assembly configured to sense a characteristic in the cavity.
