Reducing oscillation transmission through the pipe compensators is important for vibration transmission reduction through the pipes of numerical engines. The latter becomes especially relevant in the conditions of permafrost and the observed global warming when vibration transferred by pipelines can lead to soil subsidence and accidents. The design of vibration-insulating compensators based on thin-layer rubber-metal elements (TRME) is considered to improve vibration isolation of power equipment along pipelines with liquid for the frequencies from 10 to 1,600 Hz by order of magnitude or more in comparison with existing expansion joint designs. The model shows experimentally the possibility to reduce further vibration transfer by means of a series connection with a 90 ° turn of two expansion joints with TRME. This provides a reduction in the vibration transfer through the compensators by 20 - 40 dB or more at frequencies from 10 to 400 Hz due to a significant decrease in the torque (rotational) rigidity of two compensators with TRME in comparison with a single one.
