CERAMIC COMPENSATION ELEMENT FOR RADIAL AND AXIAL MOBILITY WITH PROTECTION AGAINST WATER PENETRATION Russian patent published in 2013 - IPC F16L51/02 F16L59/21 

FIELD: construction.

SUBSTANCE: device comprises a process pipe, exiting from a hot chamber into a cold chamber via a pipeline section, entering an opening in a wall, insulation on a wall, an inner insulating pipe, which surrounds the process pipe and an outer insulating pipe, which lies on the inner part of the pipeline section, an angular flange, which connects the end of the outer insulating pipe distant from the wall, with the process pipe and an approximately cylindrical hollow flexible fabric compensation element, which is connected with the outer surface of the pipeline section and the angular flange. Between the inner insulating pipe and the outer insulating pipe there is a lateral play. The additional insulating pipe is arranged oppositely to the process pipe and stretches from the angular flange and is fixed in close proximity to the latter. At the lowest temperature the additional pipe stretches to the end of the inner insulating pipe, most distant from the wall, and at the highest working temperature it forms a gap with the specified surface, forming the gap relative to the outer insulating pipe under all working temperatures.

EFFECT: invention improves reliability of a joint.
