A joint seal system and method may include a seal and a band. The seal may be positioned between abutting flanges of two adjacent duct sections. A band may be positioned over the two flanges and the flange interface. The joint seal system and method may be configured to mitigate and/or eliminate leakage of pressure, flue gases, condensate, and/or any other fluid, gas, and/or vapor between abutting flanges of duct sections at a flange interface.

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 subsea arrangement including a base structure; a tubular member rotatably mounted to the base structure through an annular bearing, wherein a section of the envelop surface of the tubular member is covered by a layer of thermally insulating material; a ring-shaped insulating member of open cell polymer foam mounted to the tubular member, wherein an inner edge of the insulating member is in contact with the envelop surface of the tubular member and the insulating member protrudes radially from the tubular member. The insulating member is positioned between an inner edge of the layer and the annular bearing with a first lateral surface of the insulating member in sliding contact with the inner edge of the layer and with an opposite second lateral surface of the insulating member in contact with a part of the annular bearing.

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.

Each of a pair of couplers includes: a vacuum double-pipe structure main part; a valve seat forming an opening through which a fluid flows; and a valve body in the main part. The valve body is configured such that, when separating the couplers, in each coupler, the body is brought into contact with the seat by a spring to close the opening, and when coupling the couplers, the body of each coupler is pressed by the body of the other coupler to move away from the seat and open the opening. The valve body includes: a holding member holding a sealing material sealing between the body and the seat when the body is in contact with the seat; a resin block covering a distal end surface of the holding member; and a metal operating member accommodating the block and protruding from the holding member to pass through the opening.

A thermally insulated transfer line for a deep-cooled fluid. The thermally insulated transfer line includes a process line for conduction of the fluid; an insulation envelope lying radially outside the process line and extending in a longitudinal direction of the process line; an insulation space arranged between the process line and the insulation envelope; and a coupling element provided at both ends of the thermally insulated transfer line, to connect the transfer line to a cryogenic tank, the coupling element being operable to attach the process line to a tank process line of the cryogenic tank and thereby establish a fluid-conductive connection between the process line and the tank process line. The coupling element includes an end piece, wherein the insulation envelope transforms into the end piece, and a connecting sleeve arranged concentric to and radially on an outside of the end piece so as to be attached to the end piece. The thermally insulated transfer line also includes a sliding coupling sleeve operable to connect the connecting sleeve to the cryogenic tank.

A thermally insulated transfer line for a deep-cooled fluid. The thermally insulated transfer line includes a process line for conduction of the deep-cooled fluid, an insulation envelope lying radially outside the process line and extending in a longitudinal direction of the process line, and an insulation space between the process line and the insulation envelope. The process line and the insulation envelope, at least in portions along a length in a longitudinal direction of the thermally insulated transfer line, have a U-shape, or a V-shape, or meandering form, or a helical form.

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 support clamp is provided for supporting an elongate object. The support clamp can include a clamp body that forms a cylindrical sleeve and a collar that extends radially inwardly from the cylindrical sleeve to provide an internal passageway sized to receive the elongate object. The clamp body can include first and second clamp sections that can each have, respectively, a sleeve wall that forms part of the cylindrical sleeve and a collar wall that forms part of the collar and includes an edge that extends radially between the sleeve wall and the internal passage. The edge of the first clamp section can include a channel profile, and the edge of the second clamp section can include a protruding profile. The protruding profile can be received into the channel profile to removably secure the first and second clamp sections together.

A plug-in coupling for connecting a first to a second double-walled, vacuum-insulated cryogenic line includes a coupling plug and a coupling socket. The coupling plug has an inner and an outer pipe piece and a first connecting flange and is connected to the first cryogenic line. The coupling socket has an inner and an outer pipe piece and a second connecting flange and is connected to the second cryogenic line. In an assembled state of the plug-in coupling, the coupling plug has been plugged into an open annular gap in the coupling socket. The annular gap is surrounded both at its inner circumference and at its outer circumference by an insulating vacuum, whereby the thermal insulation of the plug-in coupling is improved. This construction makes possible a shorter design of the plug-in coupling, which, while achieving good thermal insulation, is space-saving and easy to handle.
