FIELD: pipeline systems.

SUBSTANCE: invention relates to the various purpose pipeline systems, in particular to the flexible compensating hoses, designed for use in hydraulic systems for the liquid media transportation through the pipelines under conditions of excessive pressure and vacuum. Angular compensating hose is made in the form of arc from 0° up to 180° and consists of cover layer, inner sealing cavity and load bearing frame including cord layers. Inner sealing cavity is made of insulated from each other capillaries of the same diameter and the same length, laid like the curved steel rope strands. Space between the capillaries is filled with the rubber mass.

EFFECT: technical result: reduction in the acoustic noise propagation in the pipeline systems.
