Abstract
PURPOSE: To manufacture easily a stepped pipe differing greatly in diameter by performing strong and stable welding by forming a flange by benting a large-diameter pipe inward while forming a collar outside of a small-diameter pipe, and then by welding the both pipes by butting.
CONSTITUTION: Large-diameter pipe 10 is bent inward at the terminal to form inside reinforcing flange 11. Small-diameter pipe 12 is expanded outward to form collar 13. These flange 11 and collar 13 are fitted together to constitute edge part 14. Edge part 14 is welded to complete a stepped pipe of thick pipe 10 and thin pipe 12. Reinforcing flange 11 bent inward provides strong and stable welding and its curvature and the shape of the collar of the expanded part are freely varied to manufacture easily the stepped pipe differing greatly in diameter. In addition, only one weld part is required, therefore, beautiful and safe pipe is obtained.
