Apparatus and method for maintaining temperature in a sub-sea device, in particular in relation to fluid in the device. A material having a high latent heat on phase change is used to release latent heat to the fluid when the fluid temperature decreases towards a threshold value.

A process for assembling a coil clad hose includes suspending a spring wire helix between carriages mounted on a rail, rotating one of the ends of the helix to expand the helix, inserting a hose through the expanded helix, contracting the helix onto the hose, installing an end fitting onto each end of the hose, fixing one end of the helix together with the ferrule and the hose at one end of the hose, adjusting a pitch of the helix along the hose to another end of the hose, and fixing the helix and the hose together with the ferrule at the another end of the hose. The apparatus includes a rail, a pair of carriages movably supported on the rail, each of the carriages having a through bore holding a tang clamp bushing therein, and a pair of cable clamp fixtures mounted one at each end of the rail.

A duct coupling apparatus includes a collar portion having a first end and a second end, a flange disposed about the collar portion in a manner that divides the collar portion into an first side and a second side, and a retaining structure extending from a surface of the flange towards the second side of the collar portion. The retaining structure and the collar portion define therebetween an annular region for receipt of a sealing element, such as an o-ring or gasket. The retaining structure prevents the sealing element from extruding outwards and/or failing when under pressure.

An apparatus for forming and sealing an adjustable duct member for use in an air handling system. At least one work station accommodates a tapered work piece. A repositionable die is positioned relative to the work piece, and a cutting and forming assembly cooperates with the repositionable die to cut the work piece and form a coupling bead to reconnect the members together. A sealing assembly cooperates with the first repositioning die to seal the coupling bead in the first and second members. The work station includes an insertion channel having predetermined dimensions to accommodate at least a portion of the work piece. A clamping assembly is associated with the insertion channel to securely hold the tapered work piece at the predetermined position during the cutting and forming and sealing operations.

Embodiments of the present disclosure are directed to a fluid connection including a plurality of flexible polymeric tubes; an integral fluid connector coupled to and in fluid communication with each of the plurality of tubes; and a shell disposed over and encapsulating the fluid connector. The fluid connection surprisingly exhibiting significant increases in the working pressure, particularly in biopharmaceutical fluid transfer systems.

A fire hose coupling includes a substantially annular body having a first end adapted to connect to a fire hose and a second end having male threads. The annular body has a central bore. The coupling includes circumferentially spaced-apart lugs extending radially outwardly from an outer surface of the first end of the body. The coupling further includes a protective shoulder extending radially outwardly from the body between the male threads and the lugs. The protective shoulder has an outer diameter greater than an outer diameter of the male threads to thereby protect the male threads.

Methods for producing an expansion compensator by: providing an inner plastic liner having first and second spaced apart ends, an inner surface, an outer surface, and an interior volume extending from the first end to the second end; positioning the inner plastic liner interior of an elongate metal conduit, the elongate metal conduit having first and second spaced apart ends, an inner surface, an outer surface, and an expansion/contraction section; applying pressure to a fluid positioned in the interior volume of the inner plastic liner while the inner plastic liner is at or above a forming temperature to expand the inner plastic liner whereby the expanded inner plastic liner has an expansion/contraction section; and cooling the inner plastic liner to below the forming temperature.
