The present invention relates to an apparatus for buffering the impact on the pipe, which is mounted on the outside of the pipe to buffer impact applied from the outside of the pipe, thereby preventing damage to the pipe and, more specifically, to an apparatus for buffering the impact on the pipe, which comprises a first buffering unit for absorbing vibration and impact using flow resistance of a fluid and a second buffering unit for controlling an amount of oil filled therein using elasticity of a spring to prevent damage to the pipe caused by impact applied to the pipe. To this end, the present invention provides the apparatus for buffering the impact on the pipe, comprising: a first buffering unit including a first cylindrical housing filled with oil, a first piston moving inside the first housing, and a check valve mounted inside the first piston to generate flow resistance and a second buffering unit including a second housing having a third chamber filled with oil therein, a second piston moving inside the second housing, and a spring providing an elastic force. |
