PIPE FIXING METHOD

PROBLEM TO BE SOLVED: To provide a pipe fixing method to improve the accuracy in relative positions of pipes without generating the co-rotation of the pipes in fixing the pair of pipes to an object. SOLUTION: This fixing method of the pair of pipes 4, 5 being screwed to a hydraulic unit 3 in screw axial directions Q1, Q2 in parallel with each other and having an intersection part 8, comprises (1) a process for temporarily fixing each one end side of the pipes 4, 5 to the hydraulic unit 3, (2) a process for mounting an interval holding member 9 on the intersection part 8 for holding an interval at the intersection part 8, of the pipes 4, 5, and mounting a connecting member 7 for radially connecting the pipes 4, 5 at positions near longitudinal other end side with respect to the intersection part 8 of the pipes 4, 5, where the pipes 4, 5 are extended approximately in parallel, (3) a process for finally fastening one of the pipes 4, and (4) a process for finally fastening the other pipe 5 after finally fastening the pipe 4.
