DOUBLE-SIDED FLEXIBLE CONNECTIONS OF PIPES, HAVING MAIN AND ADDITIONAL ANNULAR ELASTOMER FLEXIBLE ELEMENTS LOCATED ON ONE AXLE Russian patent published in 2014 - IPC F16L27/103 

FIELD: construction.

SUBSTANCE: bilateral flexible pipe connection comprises the first and second extension pipes, disposed at the opposite ends of an outer body, and the first and second major annular elastomer flexible elements, designed with the possibility to install the first and second extension pipes on the outer body. An inner body is located within the outer body, the first and the second additional annular elastomer flexible elements disposed in the inner body, are designed with the possibility to install the first and second extension pipes on the inner body. A load on the first and second extension pipes brings each of the first and second main flexible elements and each of the first and second additional flexible elements into the compressed state. The first and second additional flexible elements limit the fluid pressure in the first and second expansion pipes, so that the first and second main flexible elements are not subject to the fluid pressure inside the first and second extension pipes.

EFFECT: structure improvement.
