SYSTEM FOR PRESSURE ISOLATION IN FLEXIBLE PIPE JOINTS Russian patent published in 2013 - IPC F16L27/103 

FIELD: transport.

SUBSTANCE: flexible pipe joint elastomer compensators of inclination arranged coaxially on inner radius at common centre of revolution and, at least, one elastomer inclination compensator arranged at outer radius. Said inclination compensators at inner radius are sequentially connected between expansion pipe and flexible joint case. Inclination compensator at outer radius is mechanically connected with inner compensators of inclination. Said inner compensators of inclination isolate inclination compensators at outer radius of transferred fluid. Inclination compensator at outer radius reduces axial contraction of inner inclination compensators. Therefore, inner compensators may have decreased radius and different arrangement for control over high heating load and pressure. Invention covers several versions hereof.

EFFECT: higher reliability.
