The present invention relates to a corrugated hose. The corrugated hose comprises at least one conductor arrangement. The conductor arrangement is arranged on the corrugated hose or introduced into the corrugated hose in such a manner that any damage to the at least one conductor arrangement causes a change in a signal carried in the at least one conductor arrangement such that damage to or a state change in the corrugated hose can be derived from the change in the signal.

A termination fitting assembly for use with a conduit includes the conduit comprising a primary pipe positioned centrally within a secondary pipe along a longitudinal axis of the conduit and the conduit having an interstitial space defined between the primary pipe and secondary pipe. The termination fitting assembly includes an interior fitting having an inner wall and an outer wall, the inner wall sized and shaped for insertion into and sealing with the primary pipe, and the outer wall extending circumferentially around the secondary pipe of the conduit. The termination fitting assembly includes an annular channel defined between the inner wall and the outer wall of the interior fitting and in fluid communication with the interstitial space of the conduit and an exterior fitting positioned around the conduit.

The present disclosure provides systems, apparatuses, and methods for measuring submerged surfaces. Embodiments include a measurement apparatus including a main frame, a source positioned outside a pipe and connected to the main frame, and a detector positioned outside the pipe at a location diametrically opposite the source and connected to the main frame. The source may transmit a first amount of radiation. The detector may receive a second amount of radiation, determine a composition of the pipe based on the first and second amounts of radiation, and send at least one measurement signal. A control canister positioned on the main frame or on a remotely operated vehicle (ROV) attached to the apparatus may receive the at least one measurement signal from the detector and convey the at least one measurement signal to software located topside.

A teat dip fluid manifold and methods for distributing teat dip fluids, and including redundant valve sets and pressure monitoring between valve pairs to determine valve condition.

Apparatus and method for shielding leakage from a flanged pipe coupling comprising: a housing having a front wall, a rear wall, and a top wall, the top wall depending downwardly to form side walls intermediate the front and rear walls thus forming a closure having a bottom which is open; wherein the housing contains an interior space in between the front and rear wall and below the top wall, the interior space shaped to fit around a flanged pipe coupling; and wherein the housing is shaped so as to prevent rotation of the apparatus with respect to the flanged pipe coupling.

A connection assembly between two portions of a line including an inner conduit for transporting a cryogenic fluid, the assembly including two flanges which are respectively arranged at the ends of the line portions and which are configured to be held in contact with one another by virtue of a fixing arrangement. The contact zone between the two flanges includes at least two grooves for positioning seals and at least one conduit opening out, for the one part, between the two seals and, for the other part, into an expansion chamber for the cryogenic fluid. The expansion chamber is arranged in one, or in the vicinity of one, of the first connection flange and the second connection flange. The expansion chamber includes a detector for detecting the presence of the cryogenic fluid in the expansion chamber or a recess configured for the installation of such a detector.

The present disclosure provides systems, apparatuses, and methods for measuring submerged surfaces. Embodiments include a measurement apparatus including a main frame, a source positioned outside a pipe and connected to the main frame, and a detector positioned outside the pipe at a location diametrically opposite the source and connected to the main frame.

The detector may receive a second amount of radiation, determine a composition of the pipe based on the first and second amounts of radiation, and send at least one measurement signal. A control canister positioned on the main frame or on a remotely operated vehicle (ROV) attached to the apparatus may receive the at least one measurement signal from the detector and convey the at least one measurement signal to software located topside.

A teat dip fluid manifold and methods for distributing teat dip fluids, and including redundant valve sets and pressure monitoring between valve pairs to determine valve condition.

A fire sprinkler system according to one aspect of the present disclosure includes a pipe having a first pipe portion and a second pipe portion. The first pipe portion includes a wall having a first wall thickness, and the second pipe portion includes a wall having a second wall thickness that is greater than the first wall thickness. The fire sprinkler system further includes structure coupled to the pipe and defining a sealed chamber between the structure and at least the first pipe portion, and a sensor for sensing a pressure in the sealed chamber. Example corrosion monitoring devices and methods for monitoring corrosion in pipe systems, including fire sprinkler systems, are also disclosed.

Aspects of the disclosure are directed to a tube assembly comprising: a first tube having a radial exterior surface, a second tube composed of a plurality of segments, the first tube co-axially nested within the second tube, at least a first spacer coupled to the first tube, and a second spacer coupled to the at least a first spacer, where a first segment of the plurality of segments is coupled to a first axial end of the second spacer, and a second segment of the plurality of segments is coupled to a second axial end of the second spacer.
