Damper for decreasing a pipe vibration

A damper (1) for decreasing a piping vibration capable of enhancing the efficiency in decreasing the piping vibration and adjusting the weight of a weight portion according to the type of the compressor and the shape of the pipe applied to the compressor by separating a fixed portion (10) from a weight portion (20) such that the fixed portion (10) makes a direct contact with a pipe (P) and the weight portion (20) has an interval (S) from the pipe (P) without making a direct contact with the pipe (P), in which the damper (1) installed on the pipe (P) to decrease the vibration includes a fixation part (10) provided with a coupling hole (11) formed therein to be coupled to the pipe (P), and coupled and fixed to the pipe (P) such that the coupling hole (11) makes contact with an outer circumferential surface of the pipe (P), and a weight part (20) connected to the fixation part (10).
