摘要： PROBLEM TO BE SOLVED: To provide a method of manufacturing a stepped metallic tube by which the occurrence of seizure is suppressed when cold expanding a tube. SOLUTION: A plug 10 for expanding a tube including a tapered part 20 having the surface the outside diameter of which is gradually enlarged from the top end toward the tail end and a stellitic build-up layer which is formed on the surface of the tapered part is prepared. Successively, the plug 10 is inserted into the metallic tube 50 and the tube end of the metallic tube 50 is cold expanded. After expanding the tube end, the plug 10 is pulled out of the metallic tube 50.

摘要： PROBLEM TO BE SOLVED: To provide a method for more easily forming a pipe joint, a method for fitting a pipe joint to a pipe material, and a joint method using the pipe joint.
SOLUTION: The pipe joint 1 is composed of: a cylindrical large diameter part 2; and a cylindrical small diameter part 4 formed so as to have a diameter smaller than that of the cylindrical large diameter part 2 via a level difference part 3. The outside diameter of the large diameter part 2 is made larger than the inside diameter of the pipe material 5, and the outside diameter of the small diameter part 4 is made almost equal to or smaller than the inside diameter of the pipe material 5. The large diameter part 2 of the pipe joint 1 is press-fitted into either pipe material 5a to a position where a part is spaced from the level difference part 3, and the small diameter part 4 of the pipe joint 1 is inserted into the other pipe material 5b to the level difference part 3; thus the pipe material 5 is connected. The nonpress-fitted part in the large diameter part 2 serves as the remaining margin 2a for a joint, and, even if the pipe material 5 is expanded by solar radiation or the like, it is possible to cope with it.

摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method of an eccentric pipe by which the gradually changing part of an eccentric pipe is formed into a desired shape.
SOLUTION: A pipe stock having the same inside and outside diameters as those of the small-diameter part of the eccentric pipe is prepared. One end part of this pipe stock 10 is held and fixed with a pair of dies K1, K1 and the other end part is held and fixed with a pair of dies K2, K2. Either of the dies K1, K1 or the dies K2, K2 are moved by the same distance as the eccentricity of the eccentric pipe to the other in the direction orthogonally crossed with the axis of the pipe stock 10. In this way, the pipe stock 10 is bent in two places in the longitudinal direction, the one end part 11 of the pipe stock 10 and the other end part are made eccentric and also an inclined part is formed between the one end part 11 and the other end part 12. After that, the eccentric pipe is manufactured by expanding the other end part 12 and the inclined part of the pipe stock 10.
