Disclosed is a VIT apparatus for mitigating APB in a wellbore casing annulus of a HPHT deepwater well. The apparatus includes inner and outer tubes formed of 15Cr-135 martensitic stainless steel having a vacuum space therebetween and a weld formed of high yield strength alloy for joining the inner and outer tubes. A protective weld overlay formed of corrosion resistant alloy is placed over the weld. The weld and the weld overlay are formed so as not to extend into the inner bore. Also disclosed are a process for forming the apparatus, and a system and method for using the apparatus. Multiple apparatus are connected by threaded couplings to form an elongated device that can be placed within a casing within a wellbore to carry fluids from the deepwater well to a surface location. When exposed to HPHT well conditions, the vacuum in the VIT apparatus is not lost.

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.

A threaded connection partially in a self-locking arrangement includes a first and a second tubular component provided respectively with male and female threaded zone at their respective ends. Only a portion of a first portion with varying thread width of the male threaded zone cooperates by self-locking tightening with only a portion of the second portion with varying thread width of the female threaded zone when made up one into the other. The connection is able to withstand high torques required for special applications such as drilling with casing or intermediate casing.

A method for providing a fluid supply conduit configured to pass through a constrained environment, including providing a circular section tube of appropriate dimensions, die stamping the circular section tube so as to obtain an oblong section tube of oval section, providing a plurality of external stiffeners of hollowed out shape adapted to the external dimensions of the oblong section tube, assembling the external stiffeners around a portion of the section of the oblong section tube.

A method for connecting sections of a multi-bore structure in water comprises connecting the sections to bring corresponding bores of the sections into mutual alignment while those bores are each closed by a plug that excludes the water from the bores. Then, with the sections connected and the corresponding bores sealed together in fluid communication with each other, the plugs are flushed away in a flushing fluid that flows along the communicating bores.

A tubular connecting arrangement includes, a first tubular having a first shoulder and first threads, a second tubular having a second shoulder and second threads, a seal sealingly engagable to both the first shoulder and the second shoulder, an insert and a sleeve. The insert is attachable to the second tubular and configured to provide radial support to the second tubular. The sleeve threadably engagable with both the first threads and the second threads in response to being rotated in a same direction relative to both the first tubular and the second tubular such that the first shoulder and the second shoulder are moved toward one another to compress the seal therebetween without rotational movement of the first tubular relative to the second tubular.

There is provided a breech lock coupling for coupling riser sections together. The breech lock coupling may be used non-pre-loaded or pre-loaded according to the user's preferences. In addition, the breech lock coupling may be disassembled for inspection and maintenance and reassembled. A locking ring secures two coupling components together. The coupling components may be attached to opposite ends of the riser sections, such as via welding. The locking ring may be pre-attached to the first coupling component for easy storage and fast assembly. Assembly of the riser may be accomplished by inserting the second coupling component into the locking ring and the first coupling component, then rotating the locking ring with respect to the second component. Furthermore, the coupling may be pre-loaded by tightening fasteners on the locking ring to provide a more stable coupling. Unlike with traditional riser couplings, the pre-load fasteners may be tightened via hand-held tools.

A mounting assembly is provided for securing an element to a wall structure having a laminate outer cover residing adjacent to an internal thickness of compressible material. The assembly includes an anchor for engaging the wall structure and comprising a threaded outer wall for securing the anchor within the wall thickness, an elongated internal passageway for receiving an extent of an elongated fastener, and a deformable upper crown arranged about an open end of the passageway; a strut assembly coupled to the supported element; and an elongated fastener for securing the strut assembly to the anchor and wall structure. Other embodiments include a fastener assembly kit comprising a plurality of separate components to be assembled together to mount a strut member to a laminated foam wall panel, the components including an anchor, a washer assembly, a spacer, and an elongated fastener for securing the components to the wall panel.

An apparatus for connecting a first wellsite tube to a second wellsite tube includes a collar configured to engage with outer conduits of the first and second wellsite tubes. A coupling is disposed inside the collar and includes a first end axially disposed from a second end.
