PIPELINE COMPENSATING DEVICE (VERSIONS) Russian patent published in 2012 - IPC F16L51/02 

FIELD: mechanical engineering.

SUBSTANCE: pipeline compensating device comprises branch pipes and flanges. The branch pipes are connected with each other by a bent branch pipe with the branch pipes laying in the same plane. Compensating elements are represented by three bellows expansion joints compensating the travel at a solid angle. Two compensators are a part of one branch pipe, and the third one - as a part of the other branch pipe. A middle portion of the compensating device comprises a support providing the travel of the compensating device in a plane. The support is rigidly attached to a fixed member of the structure. Under the second version, the pipeline compensating device accommodates two of bellows expansion joints compensating the travel at the solid angle, and are a part of one branch pipe, while the third bellows expansion joint which is a part of the other branch pipe compensates the angular motions in the plane of the compensating device. A rotation axis of the compensator is perpendicular to the plane of the compensating device.

EFFECT: higher operational reliability of the pipeline compensating device.
