FIELD: technological processes.
SUBSTANCE: device consists of a cylindrical and two end walls, a fitting, an internal sealing chamber, an outer rubber shell with sealing annular rubber protrusions, and a reinforcing rubber-cord frame. In the conjugation areas of the cylindrical and end walls, at least, one additional rubber-cord tissue layer is on top of the rubber-cord frame layers. End portions of the additional rubber-cord tissue layer and end portions of the base rubber-cord tissue layer located at the respective radial aimed rubber-cord overlapping bands, have the same width and the same direction of threads with the threads of the radially directed rubber-cord bands. The sealing annular rubber protrusions with a cross section in the form of triangles of radius R smoothly pass to the outer rubber shell.
EFFECT: increasing the reliability of the damping device and increasing the sealing of the pipeline.
