<p>PURPOSE: A noise reduction device for pipe arrangement is provided to reduce structural noises without changing the material of a buffer pipe member by controlling the rigidity of a case surrounding the buffer pipe member according to the pressure of fluid. CONSTITUTION: A noise reduction device for pipe arrangement comprises a hollow hard case(10), a buffer pipe member(12), a pair of vibration-proof members(14), and a joint member(16). The buffer pipe member is installed inside the case and can be deformed in the radial direction. The vibration-proof members are coupled to both ends of the case and can be deformed in the axial direction. The joint member is coupled to the vibration-proof members and connected to a pipe member(18).</p> |
