A fluid loading joint includes: a first half provided at an end of a first vacuum double pipe, the first half including a first inner pipe, a first outer pipe, and a first blocking member blocking between the first inner pipe and the first outer pipe; a second half provided at an end of a second vacuum double pipe, the second half including a second inner pipe, a second outer pipe, and a second blocking member blocking between the second inner pipe and the second outer pipe; an annular inner insulator interposed between the first inner pipe and the second inner pipe; and an annular outer insulator interposed between the first outer pipe and the second outer pipe, the outer insulator surrounding the inner insulator, with a gas space positioned between the outer insulator and the inner insulator, the gas space being formed between the first blocking member and the second blocking member.

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.

The clamping device comprises a collar which has a belt able to be clamped by the reduction of its diameter and a seal disposed inside the belt by being retained axially relative to the collar. The seal is formed in a strip which is wound on itself and whose ends are configured to cooperate together via a sealing arrangement. The seal undergoes a stress towards the inner surface of the belt and is configured to be elastically deformed against this stress to allow the insertion of an annular object between the seal and the belt.

A vertical connection system for subsea connection of a first tubular member to a second tubular member, the system comprising a lower coupling member comprising an upright casing which encloses a liquid-filled space, wherein a hub of the first tubular member is fixed to the casing at an upper end thereof and the first tubular member extends through said space; and an upper coupling member, which comprises a guide frame configured to slidingly receive said casing when the upper coupling member is lowered downwards onto the lower coupling member, wherein a hub of the second tubular member is fixed to the upper coupling member. The guide frame is provided with a layer of thermally insulating material on its outside. The liquid-filled space is delimited downwards by a bottom wall formed by thermally insulating material or covered by a layer of thermally insulating material.

A coupling arrangement (100) for connecting thermally insulated, fluid-conducting lines (102, 104) has a coupling (101) comprising a first coupling part (106) and a second coupling part (108), and connecting means (110) for connecting the two coupling parts (106, 108). A covering (112) surrounding the coupling (101) is provided, which covering, on both sides of the coupling (101), in each case lies against the thermal insulation of the fluid-conducting lines (102, 104). A cavity (114) formed by the covering (112) is configured for thermal insulation between the coupling (101) and the exterior of the covering (112).

A modular, aerogel-based vacuum insulated pipe section comprising an outer conduit; an inner conduit concentrically disposed within the outer conduit with aerogel insulation and a condensable gas being disposed in the insulation space between the concentric conduits. As a stand-alone pipe section, the insulation space is at a pressure within the range of from about 100 microns Hg to about 1000 microns Hg. However, in operation, when a cryogenic fluid is traversing the inner conduit, the condensable gas condenses and the pressure within the insulation space is further reduced to range of from about 1 microns Hg to about 5 microns Hg. The vacuum insulated pipe section further includes a coupling arrangement disposed on a first end of the inner conduit and a second end of the inner conduit, the coupling arrangement configured to engage or mate with a corresponding end of another modular vacuum insulated pipe section.

The device comprises a clamping collar (10) having a belt (12) suitable for being tightened around an article, and an outer sleeve (16) disposed around the belt, the sleeve being carried by the belt by means of a plurality of fastener tabs (18). Each fastener tab (18) is fastened to the sleeve (16) by a fastening zone (18A) and extends towards the axis (A) of the collar from said fastening zone until it reaches a pinch branch (18B) that is folded back under the belt in a configuration for being pinched between the inside surface of the belt and the article around which the belt is to be tightened.

A retention device for attaching an insulation element to a V band clamp or to another device for connecting pipe ends. The retention device includes closure elements that cooperate to permit the outer and/or inner circumference of the retention device to be decreased. The retention device further includes a bendable belt segment that may be placed about an insulation element as part of an outer covering or like a type of outer covering.

A manifold assembly configured for integration with a joint cover apparatus in a ducting system to detect leaking gas comprises an elastomeric manifold block having a substantially circular inlet aperture and one or more gas passages fluidly coupled to the inlet aperture. The assembly includes a flow control valve configured to maintain a closed state in which a component of the flow control valve sealingly engages with the inlet aperture to preclude gas at the inlet aperture from flowing into the one or more gas passages until said gas reaches a pressure corresponding to a pressure threshold. The assembly also includes at least one aperture control plate disposed substantially proximate to a lower end of the manifold block and including a substantially circular opening. The aperture control plate is adapted to maintain the substantial circularity of the inlet aperture, so as to ensure a substantially fluid-tight seal.

An expansion joint that includes a rolled two-step shaped stainless steel dynamic flange welded atop a cylindrical inner sleeve, such that the inner sleeve connects on one end to gas exhaust, such that the expansion joint withstands thermal shock due to quick rise in temperatures.
