  • Hollow product, fluid processing system and joining method of hollow members
    Patent number: 7219933
    Abstract: A connecting portion (10c) of a container (10) of a catalyst converter is formed with a joining portion (15) to be joined to a joining portion (16) of a flange member (11) by spinning working, and the joining portion (15) formed by the spinning working is joined to the joining portion (16) of the flange member (11) by friction welding. One of the connecting portion (10c) of the container of the catalyst converter and the flange member (11) is extended so as to be disposed radially inward of the joining portions (15) and (16).

  • Double-pipe-structure hollow member, method of manufacturing double-pipe-structure hollow member, and fluid treating system employing double-pipe-structure hollow member
    Patent number: 6729354
    Abstract: A catalyst container of a catalytic converter is of a double-pipe structure wherein an outer periphery of an inner pipe and an inner periphery of an outer pipe are fittingly superposed on each other. The catalyst container has a catalyst installing portion, tapered cone portions extending from the catalyst installing portion with a gradually decreasing diameter, and straight connecting portions extending from smallest-diameter regions of the cone portions to the ends to be connected with connecting pipes upstream and downstream of the catalytic converter. Holes maybe formed in the cone portions of one of the inner or outer pipes to permit fluids to be displaced from the space therebetween. Such a catalyst container has sufficient rigidity and radiated noise suppression properties and thus can be reduced in weight by being thinned.
