METHOD FOR HYDRAULIC OR PNEUMATIC TESTS OF ARTICLES UNDER PRESSURE IN COURSE OF THEIR OPERATION
FIELD: machine building.SUBSTANCE: critical sizes of cracks in normal operation mode are defined. Afterwards using methods of fracture mechanics and strength of materials, such pressure and temperature for tests are determined at which the obtained sizes of critical crack do not increase during the...

| description | FIELD: machine building.SUBSTANCE: critical sizes of cracks in normal operation mode are defined. Afterwards using methods of fracture mechanics and strength of materials, such pressure and temperature for tests are determined at which the obtained sizes of critical crack do not increase during the increased interval of test frequency up to the critical crack sizes in normal operation mode.EFFECT: increased time interval between tests without deteriorated article reliability.5 dwg
Изобретение относится к области обеспечения надежности и безопасности сосудов и трубопроводов давления во время их эксплуатации. Определяют критические размеры трещин в режиме нормальной эксплуатации. Затем методами механики разрушения и сопротивления материалов находят такое давление и температуру испытаний, при которых полученные значения размеров критических трещин не дорастают за увеличенный интервал периодичности испытаний до размеров критических трещин в режиме нормальной эксплуатации. Достигается обеспечение увеличенного интервала времени между испытаниями без снижения надежности изделия. 5 ил. |
