PROBLEM TO BE SOLVED: To restrain pressure pulsation possible to be generated in a fluid pipe by arrangement of a net-like structure for preventing resonance, a protrusion for preventing resonance, and a chamfer part. SOLUTION: The fluid pipe 100 is provided with a main pipe 1 through which fluid flows, and a branch pipe 2 branching from the main pipe 1 and having a closed end on its end, and the net-like structure 3 for preventing resonance is formed inside the branch pipe 2 so as to cross a fluid passage of the branch pipe 2. In the main pipe 1, the protrusion for preventing resonance which is protruded inward the main pipe 1 may be provided on an upstream side of a position adjacent to a joint part 5 with the branch pipe 2. In the branch pipe 2, the protrusion for preventing resonance which is protruded inward the branch pipe 2 may be provided on an upstream side of a position adjacent to the joint part 5 with the main pipe 1. The chamfer part for preventing resonance may be provided on the upstream side of the joint part 5 between the main pipe 1 and the branch pipe 2. COPYRIGHT: (C)2009,JPO&INPIT |
