<p>PROBLEM TO BE SOLVED: To provide the structure of a collection part for exhaust pipes made of titanium formed that joint pipes of iron or a stainless material are fitted in respective connection ends of an exhaust pipe and a joint pipe formed of a titanium material, and the collection pipe to interconnect the two pipes is formed of iron or a stainless material, and a welding work for the collection pipe is practicable by existing welding equipment. SOLUTION: A plurality of exhaust pipes 1 made of a titanium material have exhaust connection pipe ends 1A, 1B, 1C, and 1D fitted in joint pipes 7A, 7B, 7C, and 7D made of ion or a stainless material. Further, a single joint pipe 5 made of a titanium material has an intake connection pipe end 5A fitted in a joint pipe 8A made of iron or a stainless material. The joint pipes of the two pipes are covered for joining by the collection pipe 3 formed in a division state by using an iron material or a stainless material, and the joining edge is welded and an overlap edge is welded.</p> |
