Abstract:
A catalytic reactor comprising:a substrate body including a flat sheet metal foil strip and a corrugated sheet metal foil strip disposed one upon the other and wound-up spirally to form axial flow-through passages through the substrate body, the flat strip and the corrugated strip each having a thickness less than about 0.1 mm; anda sheet metal mantle strip encasing an outer circumferential surface of the substrate body and having a connection therewith, the mantle strip having a thickness no greater than 0.5 mm;one of the mantle strip and the outer circumferential surface having impressions formed therein, and the other of the mantle strip and the outer circumferential surface having projections projecting into respective ones of the impressions to define the connection between the mantle strip and the substrate body and oppose relative axial movement between the substrate body and the mantle strip.
