METHOD OF PERFORMANCE OF STRENGTH TESTS AND TESTING OF TIGHTNESS OF DEEP-WATER TECHNICAL FACILITY INTENDED FOR OPERATION AT DEPTHS OF UP TO 11,5 km, EXTERNAL HYDROSTATIC PRESSURE AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2019 - IPC G01N3/12 G01M3/02 

FIELD: measurement technology.

SUBSTANCE: invention relates to means of testing for strength and tightness of deep-sea technical facilities. Device includes fluid-filled external high-pressure hydrobaric chamber (3), in which there is an internal hydrobaric chamber (1) of high pressure with tested object (2). Cavities of chambers (1, 3) are interconnected with sources (13, 14) of high hydrostatic pressure by means of pipeline mains (15, 16) and contain measuring devices connected by lines (18) of communication with recording equipment (19). External chamber (3) is made in the form of hermetically closed hydrobaric stand of high pressure, having in upper part hermetically closed by cover (4) opening (5) for introduction inside it of inner chamber (1) and penetration of maintenance personnel. Inner chamber (1) is made in the form of high-pressure shell capsule installed on support base (7) consisting of detachable lower part (9) and upper part (10). Upper part (10) has aperture (12) tightly closed by cover (11) for service personnel penetration inside it. Inner chamber (1) contains free volume filled with liquid or liquid together with practically incompressible bodies (17).

EFFECT: enabling adjustment of hydrostatic pressure values in each chamber separately.
