The article deals with the problem of reduction of the level of pipeline vibrations caused by resonance with disturbing frequencies of pumping units. Each pipeline vibration has to be analyzed since there are no universal methods for reducing pipeline vibrations. For vibration isolation, it is proposed to use vibration isolators on the basis of negative rigidity. The pipeline acts as a stabilizer for a vibration isolator becomes flat which reduces its rigidity and natural frequencies. Analytical calculations were performed to confirm the effectiveness of the solution. A passive vibration absorber based on the elastic element moving along the guides perpendicular to their axis creates power characteristics which are required to protect against vibrations.
