摘要： An expansion pipe joint that absorbs displacement occurring at a connection portion between an upstream pipe and a downstream pipe includes an outer tube having a downstream end coupled to the downstream pipe, an inner tube that is inserted into the outer tube and has an upstream end coupled to the upstream pipe, and a closing member having elasticity that is provided between an upstream end of the outer tube and the upstream end of the inner tube so as to close a gap between them. Then, a difference between a position in an axial direction of the upstream end of the outer tube and a position in the axial direction of the upstream end of the inner tube is within a predetermined range so that a bus line of the closing member is inclined from the axial direction.

摘要： A grooved-ended resilient expansion joint is disclosed. The expansion joint has a resilient expansion member with a central resilient portion and two resilient axially disposed cylindrical ends. Each cylindrical end has a radially outwardly raised distal cylindrical gasket portion with at least one inside shoulder having an inner diameter sized substantially the same as an outer diameter of a pipe to be joined. A pair of pre-assembled pipe couplings are provided for joining the expansion joint to a pair grooved-ended pipe segments without disassembling the coupling.

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 duct coupling system includes a first and second duct, a vibration attenuation system, a rigid ring, and a fastening system. The first duct has a first flange aligned with a second flange of the second duct. The vibration attenuating system abuts a first side and a second side of the first flange and abuts a first side of the second flange. A portion of the vibration attenuating system encircles the first duct. The vibration attenuating system is configured to attenuate vibrations passing between the first and second ducts. The rigid ring encircles the first duct and abuts the vibration attenuation system. The fastening system couples the first duct to the second duct and compresses the vibration attenuating system. The rigid ring does not contact the first duct and the first duct does not contact the second duct.

摘要： A heat shield for a bellows includes a central section, a first outer section, a first annular insert, a first annular flexion member, a first pipe, and a first rod. The first outer section includes a first outer section first end and a first outer section second end opposite the first outer section end. The first annular insert includes a first slot and is positioned within the first outer section second end. The first annular flexion member is coupled to the first outer section first end of the first outer section and coupled to the central section. The first annular flexion member facilitates movement between the first outer section and the central section. The first pipe is partially received within the first slot in the first annular insert. Movement between the first outer section and the central section causes movement between the first pipe and the first rod.

摘要： A gripping element includes a body extending lengthwise from a first end to a second end. The body includes a first wall, a second wall extending from the first wall, and a third wall extending between the first wall and the second wall. The first wall, the second wall, and the third wall collectively define a hollow interior of the body. The body also defines an opening at each of its first and second ends. The opening at each of the first and second ends is in communication with the hollow interior of the body to permit an elastomeric material to be received within the opening at the first end of the body, within the hollow interior of the body, and within the opening at the second end of the body.
