Computing the Risk of Failures for High-Temperature Pressurized Pipelines

Popis výsledku v původním jazyce

The methods for calculating the failures risks of the high-temperature pressurized pipelines are developed as the particulars of the generalized approaches for the risk assessment in stationary deterministic systems. It is considered the straight pipe as the necessary required part of pipelines, and it is proposed considering it under the internal and external pressures for the given temperature. The pipe&apos;s failures risks are measured by the gamma-percentile life. It is proposed the mathematical model representing the deterministic properties of the high-temperature pressurized pipe needed for calculating their failures risks. In this mathematical model it is took into account accumulating the irreversible strains and damages in the pipe&apos;s during operating due to the high-temperature creep, and this mathematical model is represented as the theory of creep initial-boundary-value problem and numerical solving of such problems is briefly discussed. It is proposed the general approximation of the high-temperature pressurized pipe&apos;s life depending on the internal and external operating pressures. It is considered the particular example of the high-temperature pressurized pipe made from the stainless austenitic steel, and its gamma-percentile life is computed. It is shown that the gamma-percentile life is the failures risks quantitative measure which really gives the most fully and correct characteristic of the failures risks for the high-temperature pressurized pipes during their operating, because the gamma-percentile life of the pipe is very sensitive to the value of required probability of operating without the failures.
