PROBLEM TO BE SOLVED: To provide a nonreaction type pipe coupling capable of preventing reaction from being added in a direction to a bending part, when the bending part exists on one side of a pipe.SOLUTION: An outer surface of a movable pipe 2 of a first cylinder 1 and a piston rod 5 of a second cylinder 4 are connected by a connecting arm 7, and the inside of the first cylinder 1 and the inside of the second cylinder 4 are connected by a communicating part 8. One end in the axial direction of the first cylinder 1 and the other end in the axial direction of the movable pipe 2 are connected by a pipe 9 and a pipe 10. Thus, the reaction in the axial direction generated on one side of the pipe by internal pressure, can be removed by a piston 6. |
