FIELD: machine building.
SUBSTANCE: device for connection of double pipes with a jacket, which contain two fixed flanges and a locking member for connection of fixed flanges in axial direction. Fixed flanges includes an inner ring and an outer ring, which are connected to each other with possibility of transmitting a torque moment. Inner pipe is connected to each of the inner rings. Pipe of the jacket is connected to each of the outer rings. Fixed flanges have at least one axial hole between the inner ring and the outer ring and are located at some distance from each other due to annular space. For couplings with double pipes, which cannot be offset in axial direction relative to each other, a retractable pipe that is offset in axial direction is installed at least between one of the outer rings and the jacket pipe connected to it.
EFFECT: easy assembly is provided.
