PROBLEM TO BE SOLVED: To easily connect each end of the fixed pipes arranged at narrow distance by a connecting pipe. SOLUTION: The pipe connection method connects each end of the fixed pipes 1, 2 fixed with an distance almost coaxially by a connecting pipe 10. The first gradient cut end face 7 is formed to at least one end of the fixed pipe 1, 2 beforehand and the connecting pipe 10 having the longer length than the distance between ends of the fixed pipe 1, 2 and the second gradient cut face 11 corresponding to the first gradient cut end face 7 is supported by the fixed pipe 1, 2 by engaging it to an engagement part 8, 9 at the end part of each fixed pipe 1, 2 so that the second gradient cut end face 11 faces to the first gradient cut end face 7 and both ends of the connecting pipe 10 are fixed to each end part of the fixed pipe 1, 2.
