CONNECTING STRUCTURE FOR CRYOGENIC PIPES FOR HYDROCARBONS TRANSPORTATION Russian patent published in 2011 - IPC F16L27/02 

FIELD: machine building.

SUBSTANCE: connecting stricture for cryogenic pipes for hydrocarbons transportation consists of first and second sections of cryogenic pipe each having metal wall and flexible section of pipe connecting first and second sections. A hinged frame has the first set of levers connected with the first section of the pipe by means of ends of the base, and a supporting ring around the flexible section of the pipe pivotally attached to hinged end parts of the first set of the levers. The first set of the levers rotates around the first axis. The second set of the levers is connected with the ends of the base to the second section of the pipe and is attached to hinged end parts to the supporting ring. The second set of the levers rotates around the second axis passing across the first axis wherein the ends of the base of the first and second set of the levers are connected with the first and the second sections of the pipe via at least one connecting element passing crosswise relative to a corresponding section of the pipe.

EFFECT: increased reliability of connection.
