Abstract: A method for producing a tube with a bent progression or with a bend embodied as a transverse progression. For bending the tube or for each fold of the transverse progression, two miter cuts are made into an essentially straight tube, thus creating two tube sections with miter cut surfaces extending along the cutting planes and a cutting wedge. The miter cuts are placed such that the cutting planes intersect at a point located inside the tube wall, and at this point a bendable bar is left intact connecting the two tube sections. The miter cuts are made such that the cutting wedge first remains in the tube via not-severed or incompletely severed holding points for tube transport. The cutting wedge is then removed and the miter cut surfaces of the two tube sections are folded onto each other around the bar which acts as a hinge and then allows both tube sections to be welded together all around their miter cut surfaces.

The two brackets (2, 3) have, at their free ends opposite the one end, complementary catch structures (5, 6) by which the two brackets (2, 3) can be locked with each other in the assembled state.

The outer pipe (2) also has a smooth central section (5), first and second corrugated metal tube sections (3; 4) and smooth first and second end sections (6; 7). The inner pipe (8) is permanently fixed to the outer pipe (2) by a continuous joint (9) extending around the central section (5) and the rectilinear exhaust-gas conduction component (1) is approximately axially symmetrical in relation to a central transverse axis (10). The exhaust-gas conduction component is especially suitable in utility vehicles for linking an emission control unit to an internal combustion engine.

Abstract: A method and preprocessed tube for producing a tube with a bent progression or bend embodied as a transverse progression. For the bent position of the tube or for each fold of the transverse progression, two miter cuts are made into an essentially straight tube, creating two tube sections with miter cut surfaces extending along cutting planes and a cutting wedge. The miter cuts are placed such that the cutting planes intersect at a point located inside the tube wall, and at this point a bendable bar is left intact connecting the two tube sections. A folding of the miter cut surfaces of the two tube sections onto each other around the bar acting as a hinge allows both tube sections to be welded together around their miter cut surfaces. An additional centering aid formed by a protrusion and a recess can be provided in the opposite miter cut surfaces.

Abstract: An attachment connection (1) for connecting thin-walled hose lines (2) to a carbon-containing attachment part (3), in particular made of cast iron, in which the hose line (2) is secured on the attachment part (3) by welding. This makes it possible to achieve an in particular gas-tight connection between the hose line (2) and the attachment part (3) and, in addition to advantageous production costs, this connection is requires only a small amount of installation space, which, for example in the case of the hose line (2) being configured as a bellows, allows an increase in the number of bellows corrugations and thus, with the same amount of installation space, an increase in flexibility associated with a longer service life.

For the bent position of the tube or for each fold of the transverse progression, two miter cuts are made into an essentially straight tube, thus creating two tube sections with miter cut surfaces extending along the cutting planes and a cutting wedge. The miter cuts are placed according to the invention such that the cutting planes intersect at a point located inside the tube wall, and at this point a bendable bar is left intact connecting the two tube sections. A folding of the miter cut surfaces of the two tube sections onto each other around the bar acting as a hinge then allows both tube sections to be welded together all around their miter cut surfaces. Preferably an additional centering aid in form of a protrusion and a form-fitting recess is provided in the two opposite miter cut surfaces.
