A thermal protection device includes a cover including a wall, according to a longitudinal axis, with a rear portion adapted to be mounted on the connector so as to surround it at least partially and with a front portion adapted to be mounted on the tubular element and to hold it by a mechanical connection.

A coupling connection device includes a line coupling connector and a wind guard. The line coupling connector has first and second coupling elements, fitted together in an axial direction. Arresting means of the first coupling element engage with the second coupling element. The wind guard has a plastic shell with a first part-shell and a second part-shell, enclosing a receiving space, and forming first and second line openings, which connect the receiving space to the surrounding region. The first coupling element is coupled in an axially fixed manner in the axial direction to the first part-shell and/or the second part-shell in the receiving space by interlocking engagement. By a movement of the wind guard in the axial direction and away from the second coupling element, an arresting means can be actuated and the first coupling element can be separated from the second coupling element.

An embodiment of the duct coupling arrangement 1 includes a first coupling member 2 that is configured for axial connection to a first length of ducting 3. The first coupling member 2 defines a male coupling formation. A second coupling member 9 is also configured for axial connection to a length of ducting, the second coupling member defining a female coupling formation. The male coupling formation and the female coupling formation are configured to make an interference fit with each other so as to toollessly axially couple to, and de-couple from, each other.

A detachable coupling device with automatic closure for the transport of fluid, including two fluid transport pipes extending in a longitudinal direction and each having, at one connection end, a valve mechanism, the device also including an external tube disposed around each transport pipe and, in the coupled position, the two connection ends are configured to be relatively longitudinally displaceable between a first configuration, in which the valve mechanisms are closed, and a second configuration, in which the valve mechanisms are open, the transition from the first configuration to the second configuration being realized by a relative longitudinal movement of the two valve mechanisms close to one another.

A fluid coupling includes a first coupling member, a second coupling member configured for connection with the first coupling member, and a sleeve disposed at least partially around the first coupling member and/or the second coupling member. In embodiments, the sleeve may include a first flame-retardant layer, a second flame-retardant layer, a third flame-retardant layer, and at least one reinforcement of a non-rubber, rigid material.

Embodiments of the invention are directed to a male connector for establishing a line-seal for transport of fluids between pipes. The male connector is structured to increase a seating pressure of the line-seal. The male connector comprises a male portion provided at one end of the male connector. The male portion typically comprises a conical sealing frustum provided at one end of the male connector, such that the conical sealing frustum comprises convex sides. Moreover, the male connector is structured to be operatively coupled to a predetermined female connector such that the conical sealing frustum forms a substantially line-seal with the predetermined female connector for transport of a process fluid therethrough.

A connector for connecting a gas pipe and a heating component of a wire bonder includes a first connection end for connecting the connector to the heating component, and a second connection end for connecting the connector to the gas pipe. A heat-insulation tube is connected between the first connection end and the second connection end. The heat-insulation tube is made of a heat-insulation material and configured to insulate or reduce heat transfer between the first connection end and the second connection end. The connector may further include a first fastening sleeve for fastening the connection between the first connection end and the heat-insulation tube, and a second fastening sleeve for fastening the connection between the second connection end and the heat-insulation tube.

A breakaway valve for a cryogenic fluid tank includes a tank-side valve and a nozzle-side valve. The tank-side valve is connected to and forms a first vacuum-insulation layer with a first jacketed hose. The first jacket support includes first bellows configured to reduce heat transfer with the first vacuum-insulation layer and one or more first bellow supports that include first teeth inserted between and engaging the first bellows to provide structural support to the first bellows. The nozzle-side valve is connected to and forms a second vacuum-insulation layer with a second jacketed hose. The second jacket support includes second bellows configured to reduce heat transfer with the second vacuum-insulation layer and one or more second bellow supports that include second teeth inserted between and engaging the second bellows to provide structural support to the second bellows.

An insulated subassembly for connecting pipelines, containing two insulating half shells made from an insulating plastics, in each case a housing half shell surrounding an insulating half shell, wherein the housing half shell surrounds the outer peripheral surface of the insulating half shell, and at least one hinge connecting the housing half shells, wherein the insulated subassembly contains at least one coupling, preferably quick couplings, positively surrounded by the insulating half shells, and integral closure elements are arranged on the housing half shells.
