CATALYST SUPPORT BODY WITH CORRUGATED SLEEVE AND METHOD FOR PRODUCTION THEREOF

摘要

The invention relates to a catalyst support body (1) with a geometrical longitudinal axis (10), comprising a honeycomb body (2) and a housing (3). A corrugated sleeve (4) with an outer side (5) and an inner side (6) is arranged between the honeycomb body (2) and the housing (3). The corrugated sleeve (4) is connected to the housing (3) at connection sections (26) on the outer side (5) thereof by soldering, characterized in that the connection sections (26) essentially lie on a common circumference line and have a width (11) which is as narrow as possible in the direction of the longitudinal axis (10), however, are of such a size that, due to the total surface area thereof, the honeycomb body (2) is securely fixed under operating conditions. A high retention degree for the connection between the honeycomb body (2) and housing (3) can thus be achieved even with a shrinking of the diameter of the honeycomb body (2) on the front faces (21) during the life thereof.
