Double-pipe-structure hollow member, method of manufacturing double-pipe-structure hollow member, and fluid treating system employing double-pipe-structure hollow member |
摘要 |
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.
