Method for joining a fluid conduit and a connection hub. There is provided a method for joining a fluid conduit 2 and a connection hub 7, wherein a fluid 2 conduit is provided having an at least partially transparent end section 1. Also provided is a connection hub 7 comprising a hub cavity 9 having a shape complementary to a shape of the end section of the fluid conduit 1. The end section of the fluid conduit 1 is at least partly introduced into the hub cavity 9 through an opening in the hub, wherein a contact interface between at least a lateral wall part of the end section 1 and a hub cavity 9 wall is established. The method includes heating a target zone 27 in the contact interface, for joining the fluid conduit 2 and the connection hub 7 at the target zone 27, by directing a light beam 29 across the at least partially transparent end section 1 of the fluid conduit 2 from a side of the fluid conduit 2 which is opposite a side of the target zone 27.

A hose assembly includes a metal hose, an end connection having a distal end defining a fluid connector and a proximal end defining a tube stub received in a distal end portion of the hose, and a weld collar surrounding the distal end portion of the hose and the tube stub of the end connection, with the weld collar, the hose distal end portion, and the tube stub being welded together at a welding zone proximal to a distal edge of the metal hose.

A hose assembly includes a corrugated metal tube having a plurality of corrugations and an outer cuff portion extending from an endmost one of the plurality of corrugations, radially outward of an inner diameter of the endmost corrugation, an end connection having an outer end defining a fluid connector and an inner end defining a nose portion received in the outer cuff portion of the corrugated metal tube, and a collar surrounding the outer cuff portion of the corrugated metal tube and the nose portion of the end connection. The collar, the outer cuff portion, and the nose portion are welded together.

A pipe device includes a pipe and a connection element. The pipe has a pipe jacket that has an inner surface and an outer surface and forms a flow channel. The connection element forms a through-channel that extends from a connection piece consisting of a first material (M1) and having a first opening to a second opening. The pipe jacket is positioned on the connection piece with a first pipe end consisting of a second material (M2). A bonded connection is formed between the first material (M1) and the second material (M2) in a contact region between the inner surface of the pipe jacket and a peripheral surface of the connection piece.

A hose assembly includes a corrugated metal tube having a plurality of corrugations and an outer cuff portion extending from an endmost one of the plurality of corrugations, radially outward of an inner diameter of the endmost corrugation, an end connection having an outer end defining a fluid connector and an inner end defining a nose portion received in the outer cuff portion of the corrugated metal tube, and a collar surrounding the outer cuff portion of the corrugated metal tube and the nose portion of the end connection. The collar, the outer cuff portion, and the nose portion are welded together.

A pipeline connection structure includes a first pipe body, a second pipe body, and a connection sleeve assembly, wherein the first pipe body and the second pipe body are connected by the connection sleeve assembly. A compressor assembly has the pipeline connection structure.

The present invention relates to a pipe (1, 3) having a pipe element (3) for conveying a medium in a flow direction (A) and having a flange element (1) for connecting the pipe element (3) to a connection partner, wherein the pipe element (3) has a pipe body (30) with a media passage opening (31) for conveying the medium in the flow direction (A), wherein the flange element (1) has a flange body (10) with a media passage opening (11) for conveying the medium in the flow direction (A), wherein the flange element (1) is arranged at one end of the pipe element (3) in such a way that the media passage openings (11, 31) at least substantially overlap. The pipe (1, 3) is characterized by a sensor element (21) which is arranged in the flange body (10) in such a way that at least a portion of the sensor element (21) can be in contact with the medium.

Connecting assembly of a gas cooking appliance that includes a flexible tube and a connector fixed to a first end of said flexible tube, the connector being configured to be directly connected to an opening of a manifold of the gas cooking appliance.

A method for repairing a turbine housing of an air cycle machine is provided. The method comprises: removing damaged material from a journal bearing bore of the turbine housing; forming the journal bearing bore to an inner diameter of about 2.580±0.001 inches (6.553±0.003 centimeters). The journal bearing bore having an inlet and an outlet. The method also comprises determining the inner diameter of the journal bearing bore; and forming a cylindrical insert having a first end, a second end, an inner surface, a step located at the first end, and an outer surface with an outer diameter that provides a diametric interference with the inner diameter of the journal bearing bore. The diametric interference being between about 0.000-0.003 inches (0.000-0.008 centimeters). The method further comprises inserting the second end of the cylindrical insert into the inlet of the journal bearing bore up to the step.

An assembly includes at least one member having first and second ends. A dual metal adapter for connecting to the at least one member includes an inner tube for receiving and contacting the first end of the at least one member and being formed from a first metal having a first resistivity. An outer tube extends over the inner tube and is secured thereto. The outer tube is formed from a second metal having a second resistivity greater than the first resistivity. The first end of the at least one member is metallurgically bonded to the inner tube.
