FIELD: test equipment.
SUBSTANCE: leakage is tested on a step-by-step basis on cylindrical parts and bottoms of a cryogenic tank, but first, the above said components are tested additionally for strength with cryogenic component; then, they are welded; after that, strength test of circumferential welds is performed at normal temperature of an empty cryogenic tank considering the action of total axial load from action of excess internal pressure and external housing tensile loads, and leakage test of circumferential welds is performed.
EFFECT: enlarging the possibility of tests and their simplification, reducing costs for tests of components.
