We consider the problem of self-excitation of oscillations 
in the pipes of main gas-compressor stations. We present results of 
model investigations of intense narrow-band oscillations of pressure 
and velocity in a gas flow, which are due to the occurrence of instability 
and the formation of a self-oscillating system in the zone of a joint 
between a pipeline and a blind branch-resonator. The possibility of 
prevention or attenuation of self-oscillations is indicated.
