ABSTRACT:
A merging pipe wherein branch pipes can be easily welded to each other in a joint portion even when an intersect angle .alpha. between axes of both the branch pipes is set to a small value to reduce merging resistance. In the merging pipe, a plurality of branch pipes are obliquely arranged and bent at their joined ends to extend in the axial direction downstream of confluence. Circumferential walls of the branch pipes adjacent to each other at the joined ends are formed into abutting walls held in close contact relation. Flange walls are formed between the abutting walls and circumferential walls of the branch pipes. The branch pipes are joined together at the abutting walls along their outer peripheral edges.
