    摘要: A decoupling element for a conduit includes an interior hose made of metal and a corrugated exterior hose surrounding the interior hose, with a hollow-cylindrical gap formed between the corrugated exterior hose and the interior hose. At least one damping element is arranged in the gap, with the damping element(s) constructed of a woven fabric made of a high-temperature-resistant material and having an outside surface with at least one bulge, wherein the bulge positively engages with a corrugation of the exterior hose. The exterior hose may be a membrane bellows. The woven fabric may be a metallic material. The at least one damping element covers, along the rotation axis, preferably a proportional length of at least 20% of the hollow-cylindrical gap and has preferably a static stiffness in the radial direction of less than 100 N/mm.

    摘要: The invention relates to a metal tube arrangement (1) for exhaust pipes of motor vehicles, which typically includes an inner tube (10) with hook or interlock connection as well as a bellows-like an outer tube (20). The inner tube (10) and the outer tube (20) are hereby connected to one another at regular distances along their extension. In particular, they can be coupled to one another via a helically revolving roll seam weld (30). The outer tube (20) is preferably made of two layers from a wound metal strip (21).

    摘要: A tube is made of profiled metal strip which includes an end leg extending in parallel relationship to a tube axis, an inner leg extending in parallel relationship to the tube axis at a first distance, and an outer leg extending in parallel relationship to the tube axis at a second distance which is greater than the first distance. The inner leg is connected with the outer leg by a transition. A double-folded loop hook extends radially for connecting the end leg with one member from the group consisting of the inner leg and the outer leg, and an end hook extends radially and is connected to the other member of this group.
