Exhaust gas treatment device with pipe assembly and sliding seat

摘要

The sliding fits (15,20) have a wire fabric which supports its outer side at pipes (10,11) in a radial manner and is fixed directly or indirectly at a component. The wire fabric is fixed in a fixture which is fixed at the component. The wire fabric is made of multiple knitted fabric cushions arranged at a distance from each other and distributed in circumferential direction. The wire fabric is made of knitted fabric ring comprises pipes in the circumferential direction. Independent claims are included for the following: (1) a pipe arrangement with two thermally loaded pipes; and (2) a waste gas treatment device, particularly for an exhaust system of an internal combustion engine.
