A flexible conduit element with an end portion that is designed for attachment to a rigid conduit element. The flexible conduit includes a bellows member, an interlock member, an outer fixing member and a connection nozzle. An attachment portion of the connection nozzle extends beyond the outer fixing member and the interlock member and ends in a flared shape to form a gas-tight seal.

The present invention relates to fire-resistant pipe couplings (100) for connecting together two plain-ended pipes in a fluid-tight manner. The pipe coupling (100) comprises: a tubular casing comprising: an outer tubular casing (102); and an inner tubular casing (104), fitting entirely inside the outer casing (102); a tubular sealing gasket (106) disposed within the inner tubular casing (104); and means (116) for tensioning the casing around the gasket (106). The casing further comprises: at least one layer of fire-resistant material (124) disposed between the inner (104) and outer (102) casings; and at least one layer of thermally-insulating material (128) disposed between the tubular sealing gasket (106) and the inner casing (104), whereby the outer casing (102) and tubular sealing gasket (106) are thermally insulated from one another.

An eccentric universal joint mechanism, even when there is a lateral displacement between a first pipe and a second pipe, can absorb the displacement and connect the first pipe and the second pipe. The eccentric universal joint mechanism includes: a first sleeve; a second sleeve; and an eccentric universal joint connecting the first sleeve and the second sleeve. The eccentric universal joint includes a first eccentric pipe, and a second eccentric pipe rotatably joined to the first eccentric pipe. A displacement between the center line of the first eccentric pipe and the center line of the second eccentric pipe is determined by the rotational position of the second eccentric pipe.

An expansion loop for a piping system. The expansion loop has a first flexible conduit with a first end and a second end and a second flexible conduit with a first end and a second end. A first rigid conduit is connected between the first ends of the first and second flexible conduits. Additional rigid conduits are connected to both of the second ends of the flexible conduits. These additional rigid conduits include a stainless-steel elbow, a conversion conduit, and a copper conduit. The expansion loop may be installed wherein the flexible conduits are bent, when fluid flows, the flexible conduits straighten out and are not bent.

The present invention describes a flexible conduit element with an end portion suitable for attachment to a rigid conduit element. The flexible conduit element comprises: a bellows member; an interlock member; an outer fixing member; and an connection nozzle, where, in an axial cross section at an end portion of the flexible conduit element, the outer fixing member is disposed outside of the bellows member, the bellows member is disposed outside of the interlock member, and the interlock member is disposed outside of the connection nozzle, and a gas-tight seal connects the bellows member and the connection nozzle. A method of assembly such a flexible conduit element is also disclosed.
