Probability assessment of tightness loss pressure vessels during risk analysis technical devices for hazardous production facilities

Thick-walled high-pressure vessels are a fairly common type of technical device as part technological equipment operated at various hazardous production facilities. Reliability indicators pressure and their change during operation largely determine the failure-free whole, potential failures subject to consideration when conducting risk analysis operating equipment. The article discusses probabilistic statistical approaches solving problem predicting resource with fatigue failure neck design stages. For stage, technique is presented for modeling processes nucleation development high-cycle crack, well determining law quantitative distribution vessel by condition loss tightness. method further growth diagnosed residual life
