PRESSURISED AND ISOLATED VESSEL INSTALLED ON SUPPORTING DEVICE Russian patent published in 2014 - IPC F17C3/02 

FIELD: machine building.

SUBSTANCE: claim describes a vessel wall comprising sealing barrier (6) and supporting device (10) for equipment immersed into pressurised vessel. The sealing barrier comprises a layer of corrugated sheet metal (11), at least, with one series of parallel corrugations (15) interrupted with hatch (25) around the supporting device. The supporting device passes in a longitudinal direction through the hatch. The sealing barrier comprises connecting elements (45, 50) for tight connection of the supporting device with the edge area of the corrugated sheet metal confining the hatch. Hatch (25) interrupts a multiplicity of directrix lines (20) of parallel corrugations of the series, while the supporting device is located in a centre in the position between directrix lines (A) of two parallel corrugations (20).

EFFECT: invention is intended for building the supporting device without aggravation of the essential mechanical properties of the corrugated sealing membrane, in particular, its sealing effect and stability to thermal compression or to pressure forces.
