METHOD FOR PRODUCING HEAT-INSULATING BARRIER FOR VESSEL WALL AND HEAT-INSULATING BARRIER PRODUCED THEREBY Russian patent published in 2021 - IPC F17C3/02 

FIELD: physics.

SUBSTANCE: invention relates to a method of making heat-insulating barrier (2, 5) for wall (1) of a sealed and heat-insulating reservoir built into bearing structure (3). Method includes step of pressing insulating plug (44, 57, 58, 59, 60) in direction of bearing structure (3) to support element (15, 82, 91) for irreversible deformation of insulating plug (44, 57, 58, 59, 60, 95, 96) in place, where it rests against support element (15, 82, 91), and for irreversible reduction of insulating plug size (44, 57, 58, 59, 60, 95, 96) between inner end (48, 61) of insulating plug (44, 57 , 58, 59, 60, 95, 96) and place, where insulating plug (44, 57, 58, 59, 60, 95, 96) rests against support element (15, 82, 91), so long as inner end (48, 61) of insulation plug (44, 57, 58, 59, 60, 95, 96) does not reach a predetermined position in said opening (43, 55). Invention also relates to heat-insulating barrier (2, 5) made by such method.

EFFECT: technical result is limitation of level differences in inner support surface of sealing membrane at the level of holes.
