FIELD: testing equipment.
SUBSTANCE: invention is related to testing equipment and may be used for crushing test of casing, tubing and drilling pipe samples with smooth ends by external hydraulic pressure. Installation for crushing test of pipes by external controlled hydraulic pressure comprises hydraulic cylinders, frame, container enclosed in this frame, where multilayer winding is applied from high-strength tape, base, upper plug, lower plug, bench for assembly of pipe samples. Besides installation also contains holder for fixation of pipe sample, and upper and lower plugs joined to it, and sealing of gaps between ends of tested pipe sample and upper and lower plugs is carried out through technological sealing, which comprises steel tape wound in several layers on upper and lower joints of pipe sample and plugs, and polyurethane tape wound over mentioned steel tape.
EFFECT: improved hydraulic pressure in container till crushing of pipe sample with registration of crushing pressure.
