Exhaust gas system for motor vehicle, has coupling unit designed as repair flange halves that together with spare part flange halves form pipe coupling, where repair and spare part flange halves are permeated by common connection unit

摘要

The system has a set of pipes (1), cleaning units and/or damping units that are connected to an operating unit by a welding. A coupling unit is fixed at a suitable position of the pipes in an area of a preset disconnecting point. The coupling unit is designed as repair flange halves (5), which together with corresponding spare part flange halves (10) of a spare part form a pipe coupling (6). The repair flange halves and the spare part flange halves are permeated by a common connection unit (9), where the repair flange halves have large thickness than the spare part flange halves.
