FIELD: building.
SUBSTANCE: invention relates to the field of building and can be used in creation of high-pressure vessels operating in settings of high internal pressures, as well as temperature, radiation, and other impacts. The vessel is made of prefabricated pre-stressed elements (1,2) consisting of arc-shaped reinforced concrete elements (12,14). Channels (4), fasteners (7) for winding annular fittings (8), concrete sections (9) formed under radial stress using jacks (13) are provided in each arc-shaped element. Elements (1, 2) comprise keys (10) for secure engagement with the end elements (3) provided with process penetrations (11). The prefabricated elements (1,2) are rigidly clamped by the pre-stressed fittings (5) and secured with anchors (6).
EFFECT: increase in the reliability and longevity of high-pressure vessels.
