Title:
HOLLOW MEMBER, MANUFACTURING METHOD THEROF, FLUID DISTRIBUTION SYSTEM USING THE HOLLOW MEMBER, AND FORMING APPARATUS OF HOLLOW MEMBER
Document Type and Number:
WIPO Patent Application WO2002020208
Kind Code:
B1
Abstract:
Individual plate members (W1, W2, W3, W4, W5) that are different in plate thickness or material are joined together by mush seam welding to form a hollow material (W, W'), and the rigidity is controlled in individual parts. By spinning the rigidity material (W, W'), a junction (1b) and a cone (1c) are formed in an optimum shape, and a hollow member (1) is manufactured. Thus, the hollow member (1) smooth in juntion and high in welding strength is obtained in spite of thin plate material. When this hollow member (1) is used in a catalyst container, the sealing performance is excellent without being accompanied by an increase in radiant noise or an increase in weight.
