A coupling component having a first end and a second end, the fitting having a longitudinal axis between the first end and the second end, the first end of the component including a first tubular portion having a first internal diameter adapted to form a sliding fit with a first pipe section, and a first sealer adapted such that the first end can be sealed in use to the first pipe section; the second end having a second diameter or cross-sectional area which is larger than the first diameter and wherein the second end incorporates a flange, wherein at least part of the face of said flange is in a plane substantially non-perpendicular to, or offset from, the longitudinal axis of the component.

Systems and methods for a segmented aircraft refueling tube with a tube interface include a plurality of seals configured to deform while allowing relative movement between tube segments. The systems include a tube interface that includes a first ring, a second ring, a first seal disposed between a first ferrule and the first ring, a second seal disposed between a second ferrule and the second ring, a third seal disposed between the first ring and a sleeve, and a fourth seal disposed between the second ring and the sleeve. The plurality of seals per ring allow for misalignment between the ferrules to be accommodated by two or more seals.

A clamp assembly comprising a plurality of clamps each comprising two clamp arms pivotal relative to each other about a hinge point, and a common connector part joining two or more of said clamps to each other at their hinge points.

A clamp assembly comprising a plurality of clamps each comprising two clamp arms pivotal relative to each other about a hinge point, and a common connector part joining two or more of said clamps to each other at their hinge points.

A pipe joint including an outer pipe assembly having a first outer pipe portion, a second outer pipe portion, and a shroud coupling the first and second outer pipe portions. The outer pipe joint includes an outer securing mechanism securing the shroud to the second outer pipe portion. The inner pipe assembly, within the outer pipe assembly, includes a first inner pipe portion coupled to a second inner pipe portion via an inner pipe joint. The inner pipe assembly provides an inner fluid flow path extending axially and across the inner pipe joint. The shroud is movably mounted to the first outer pipe portion, and the outer securing mechanism is releasable so the shroud can move along the first outer pipe portion and withdrawn from the second outer pipe portion to open a gap between the shroud and the second outer pipe portion for the inner pipe joint.

A connector for two fluid conduits of different geometries includes a housing having a first and a second connection portion and a fluid channel fluidically connecting both connection portions; a locking element which can be coupled to the housing; and a seal which can be positioned between the housing and the locking element. The locking element and the housing can be positioned relative to one another with respect to the fluid channel such that a receiving portion for receiving the seal is formed between the housing and the locking housing. The first connection portion is designed to connect a first fluid conduit with an elongated cross-section and the second connection portion is designed to connect a second fluid conduit with a round cross-section.

A plug-in coupling for connecting a first double-walled vacuum-insulated cryogenic line to a second. The plug-in coupling has a coupling plug and a coupling socket. The coupling plug can be plugged into the coupling socket, these being retained in a plugged-together state by fixing means. A guide column is arranged on the coupling plug or the coupling socket. The guide column has arranged on it elastic means which, in the assembled state of the plug-in coupling, are subjected to stressing and which subject the coupling plug and/or coupling socket to an elastic force which strives to release the coupling plug and coupling socket from one another as soon as the fixing means no longer hold the coupling plug and coupling socket together. The elastic energy stored in the elastic means ensures that, in the event of an emergency, the coupling plug and coupling socket are quickly released from one another.

A method of fabricating a conduit comprises steps of attaching a first tubular-outboard-ply end of a tubular outboard ply to a first inner collar portion of a first collar with a third weld and attaching a second tubular-outboard-ply end to a second inner collar portion of a second collar with a fifth weld. The method additionally comprises steps of interconnecting the first inner collar portion and a first outer collar portion of the first collar with a first weld and interconnecting the second inner collar portion and a second outer collar portion of the second collar with a sixth weld. The method also comprises attaching a trimmed first corrugated-inboard-ply end to the first outer collar portion with a second weld, attaching a trimmed second corrugated-inboard-ply end to the second outer collar portion with a fourth weld, and communicatively coupling a first sensor with an interstitial space.

A coupling for connecting vacuum-insulated piping is disclosed. The coupling facilitates the detection of unwanted fluid ingress into the low pressure insulating outer portion of the vacuum-insulated piping and the detection of a leak from the central portion of the vacuum-insulated piping that is used to carry cold fluids. This is achieved by providing a first leak path from the central portion of the vacuum-insulated piping to a sensor outlet and a second leak path from the outer portion of the vacuum-insulated piping to the sensor outlet. One sensor may be used to detect unwanted fluid ingress into the low pressure insulating outer portion and also detect a leak from the central portion of the vacuum-insulated piping.

In the case of a hose connector assembly (1) it is provided for a retaining plate (15) to be used for axially fixing at least two hoses (6, 7, 8) in corresponding hose receptacles (3, 4, 5). The hoses (6, 7, 8) are insertable into respective recesses (16, 17, 18) of the retaining plate (15) by way of a lateral insertion movement (19), and the hoses (6, 7, 8) engage behind the recesses (16, 17, 18).
