ABSTRACT:
A tube element, especially for the exhaust systems and exhaust gas recirculation systems of combustion engines in vehicles. The element has a single- or multi-ply tube element made of metal which is provided with cylindrical end fittings and at least two annularly corrugated bellows and a connecting pipe forming a single element, with the pipe corresponding with the bellows in diameter as well as in wall thickness, and with the inside diameter of the connecting pipe corresponding substantially with the free inside diameter of the adjacent bellows. The element has a concentric reinforcing pipe at an external radial distance to the connecting pipe, with the ends of the reinforcing pipe, whose inside diameter corresponds with the outside diameter of the bellows, being connected with the radial outward crests of the first corrugations of the bellows following the connecting pipe.
