PIPELINE PRESSURE STABILISATION METHOD Russian patent published in 2013 - IPC F16L55/04 

FIELD: machine building.

SUBSTANCE: natural gas pipeline pressure stabilisation method involves dissipative and elastic damping action on natural gas flow; during the action process, natural gas pulsation suppression is performed due to deformation of piezoelectric elements, the appearing polarisation of which is closed to useful electric load, and natural oscillation frequency of piezoelectric elements is chosen close to dominant frequency response of pulsation of the pumped natural gas as to amplitude. As useful electric load, diagnostics and telemetry devices of parameters of pumped natural gas or cathode protection of pipelines are chosen. As piezoelectric elements, materials having flexible electric properties of the row containing rare-earth manganites are used. Piezoelectric elements are arranged in a fixed position along internal wall of the pipeline parallel to its axis.

EFFECT: increasing energy use efficiency of high-frequency mechanical oscillations of pumped natural gas.
