摘要： A thermal expansion compensating device has a conduit with a first opening and a second opening for connection to a first pipe and a second pipe of a hot water system, respectively, the first and second pipes being formed by removing a section from a length of pipe of the hot water system. A pre-tensioning force is applied to the device to axially displace the first opening from the second opening until after connection of the openings of the pipes. A resiliently deformable pipe segment defines a portion of the conduit between the first opening and the second opening and is resiliently deformed to a tensioned position by the application of the pre-tensioning force. Once the hot water system is activated, the pipes axially thermally expand such that the first opening moves towards the second opening and the pipe segment moves from the tensioned position towards a rest position decreasing the stress on the device.

摘要： A flexible pipe element is provided formed as a metal bellows with at least one corrugated bellows section and a bellows brim, which forms one end of the metal bellows, and a connection element for connecting the metal bellows to a continuing pipe part or to a connector, with the connection element having a connection area for abutting a contact area of the bellows brim. An annular bulge is formed in the contact area of the bellows brim and/or in the connection area of the connection element projecting beyond an average level of the contact area and/or an average level of the connection area in order to form a linear seal between the contact area and the connection area. A method for producing such a flexible line part is also provided.

摘要： A sealing system including a first end and a second end with flexible bellows extending therebetween. The first end includes a base plate with an inner ring having an inner diameter. The inner ring is configured to receive a pipe therethrough. The pipe has an outer diameter, which is smaller than the inner diameter of the inner ring. The bellows of the sealing system has a first length in a first position and second length in a second position. Upon axial expansion of the pipe, the bellows is configured to move from the first position to the second position. The sealing system may also comprise a mechanical protective element, such as a shroud which extends around the bellows. Movement of the bellows can be further limited with rods extending from the shroud to a surrounding substrate or a cable fixing a maximum distance between the pipe and the shroud.

摘要： Systems and methods according to one or more embodiments are provided for providing a durable and thermally insulated duct network. A duct network may be provided by coupling two or more foam ducts to each other. In one example, a system includes a plurality of foam ducts and a plurality of foam bellows configured to couple the foam ducts to each other. The foam bellows include one or more bellow folds to allow an expansion and contraction of the foam ducts. A plurality of structural fastening systems couple the duct network to a structure of a vessel. The structural fastening systems allow for an axial movement of the duct network as the foam ducts expand and contract. Additional systems and methods are also provided.

摘要： An expansion joint including a hollow elastomeric body having coupling flanges at each open end configured to connect to flanges of a pipe system. The hollow elastomeric body is made of a material including an elastomer and fibers. A stretchable sensor is located within the material of the hollow elastomeric body. The sensor is configured to provide a varying electrical characteristic when the sensor is stretched or contracts. An analysis circuit is connected to the sensor, the analysis circuit configured to receive the varying electrical characteristic and to emit a signal corresponding to a level of the electrical characteristic received by the analysis circuit.
