The system includes a quick union device comprising a first quick union component that is operable to couple to the upper landing string and a second quick union component that is operable to couple to the lower landing string. The first quick union component and the second quick union component respectively include a self-aligning threading interface that provides hydraulic and electrical connections when the first and second quick union components are connected to one another. The quick union device provides real-time feedback via wireless communication transducers that measure pressure and report that the measured pressure is retained in a plurality of hydraulic lines of the second quick union component when the first and second quick union components are disconnected from one another.

Abstract: An exhaust adapter secures an exhaust tube relative to an exhaust pipe. The exhaust adapter is formed to have an annular shape enclosing a through hole, and is mounted on the outer peripheral surface of the exhaust tube and on the inner peripheral surface of the exhaust pipe by inserting the exhaust tube into the through hole. When the exhaust adapter is being fitted on the outer peripheral surface of the exhaust tube, the inner peripheral surface of the exhaust adapter presses the outer peripheral surface of the exhaust tube, and when the exhaust adapter is being fitted on the inner peripheral surface of the exhaust pipe, the outer peripheral surface of the exhaust adapter presses the inner peripheral surface of the exhaust pipe.

Abstract: A connecting element for establishing a frictional connection with a neck portion of a liquid container, like a vial. The connecting element may include a basic structure and contact elements connected with the basic structure that provide contact surfaces for contacting the neck portion. The contact surfaces may be configured to form a receiving space for receiving the neck portion. The receiving space can be enlarged by moving apart the contact surfaces.

Abstract: A pipe stalk for a pipe-in-pipe pipeline, the pipe stalk including an outer pipe and at least one inner pipe located within the outer pipe, and having a retaining assembly moveable between a first configuration for preventing axial movement of the inner pipe with respect to the outer pipe in a downwards direction and a second configuration for allowing axial movement of the outer pipe with respect to the inner pipe, whereby axial movement of the inner pipe with respect to the outer pipe can be prevented when the outer pipe is held during welding to an adjacent pipe stalk.

Abstract: A power slip extends a joint from tubing disposed in casing at a well so that a casing head can install on the casing and the tubing can be packed-off from the casing. The joint attaches to an inner sleeve having collet members that fit onto the inner tubing so that the joint extends thereabove. An outer sleeve and interlocking collet assemble together and install onto the inner sleeve. The collet threads onto the inner sleeve and forces the outer sleeve downward onto the inner sleeve. Being forced, the outer sleeve causes the collet members to engage around the inner tubing. The casing head then installs on the casing with the joint extending up through the head's bowl. An H-plate installs in the open bowl around the extended joint, and another pack-off installs on the joint to pack it off from a spool attaching to the casing head.

Abstract: The present invention principally relates to a thermal insulation element (200) of cylindrical shape for a fluid transport pipe comprising an envelope (204) of longitudinal axis (X), a thermal insulation arranged in said envelope (204), the envelope (204) comprising a deformable annular zone, comprising a first (212.6) and a second (212.12) cylindrical surface that overlap and are able to slide against each other in the case of movement imposed by thermal loads applied to said pipe insulation element (200). The present invention also relates to a method of fabricating pipes for transporting fluids at high temperature, particularly hot gases, from elements according to the present invention by fitting a male connector of one element into a female connector of the other element.

Abstract: A refrigerant pipe connected to a suction side of a compressor and a refrigerant pipe connected to a discharge side of the compressor are integrated into one body. A refrigerant pipe connected to an inlet side of a condenser and a refrigerant pipe connected to an outlet side of the condenser are integrated into one body. A refrigerant pipe connected to an inlet side of a decompressor and a refrigerant pipe connected to an outlet side of the temperature detecting portion are integrated into one body. In these piping structures, a double pipe structure and a double pipe joint structure are adopted in which an inner pipe for circulating high pressure fluid and an outer pipe for circulating low pressure fluid are formed separate from each other and the respective end portions of the pipes are joined to a joint member by plastically deforming the pipes.

Abstract: An apparatus for holding in place a first casing while a second casing is connected to the first casing, including an annular clamp made up of three segments hingedly fit together to form a ring. The inner surface of each segment includes an insert within a dovetail which creates secure points of contact between the inner surface of the annular clamp and the exterior surface of the casing. The apparatus includes a carrier having two handles and a ring for transporting the annular clamp. The annular clamp can be positioned inside a bowl-shaped housing having a central circular opening adapted for receiving the annular clamp. An adapter plate can be used for retrofitting the apparatus to rigs of all makes and models.

Abstract: A fluid piping system and pipe spools are provided. The fluid piping system has at least one pipe spool. The pipe spool has an inner wall and an outer wall with at insulating area defined at least in part by the inner and outer wall. The insulating area of the pipe spool acts to isolate any leak of cryogenic fluid in the pipe spool.

Abstract: A clamp for clamping two concentric tubes, typically two concentric tubes in an oil or gas well. The clamp has two axially movable tapered components which can be pulled over one another in an axial direction to provide a contraction of internal diameter which grips the smaller diameter tube. In one embodiment, a spacer is fitted to allow the tapered components to be held apart until the tubes have been correctly positioned. The spacer is then removed, and the tapered components are drawn together to effect the clamping. A hydraulic ram can be provided to separate the tapered components should readjustment be required. In another embodiment, the larger diameter tube is made with a relatively thin wall, so that it can be distorted inwards to grip the smaller tube.

Abstract: The present invention relates to improvements in drill slip assemblies for use in holding a drill pipe or other tubular member in a vertical position above or within a wellbore. The invention comprises a plurality of slip segments assembled in a slip bowl, each segment containing a plurality of dies which grip the tubular member to prevent any axial displacement. The invention provides at least three improvements over prior art drill slips. First, the outer surface of the slip segment assembly, particularly the lower nose region, is fully supported by the inner surface of the slip bowl such that no portion of the slip segment assembly extends below the bowl. Second, the slip segments are fabricated from forged steel, making them more durable and able to carry higher loads. Third, each die in the lowermost set of hardened dies is fabricated having a rounded bottom end with a tapered profile to complement the rounded bottom of the axial grooves cut into each slip segment.

Abstract: A cryogenic fluid piping system is provided with two or more coupled pipe spools, each spool having an inner and outer pipe, the inner for carrying cryogenic fluid. The pipe spools are also configured with a bayonet connection to allow expansion and contraction of the system without failure. A leak control device and pressure relief device are included to protect the system from catastrophic failure in the event of a cryogenic fluid leak from the inner pipe.

Abstract: Slip assemblies are provided for gripping drill pipe or other tubulars such that the load is distributed along the length of the dies of the slip segments rather than being concentrated at the lowermost dies within the slip segments. The load is distributed by the fact of using a load ring around the interior surface of each slip segment to allow the load ring to absorb part of the loading rather than have all of the load supported by the lowermost slip dies. In addition, resilient members are provided at the top surface of the uppermost die and also at the top surface of the die immediately underneath the load ring to better distribute the loading between the various slip dies and also to lessen the possibility of having gaps develop between the dies of the slip segments.
