Probabilistic design factors for pipes used for hydrogen transport
Résumé
Probabilistic design factors for pipes have been established. The used method involves a risk equation. This approach is based on assumption of a risk 10 À5 probability. The results obtained are less conservative than values provided by ASME code.

The used method involves a risk equation defined as the product of probability of leakage after failure, probability to have a gas flow greater than a prescribed value, probability of ignition, probability of lethal effects greater than a threshold value and probability of the presence of a person corrected by an environment factor and a risk reduction coefficient. The results obtained are less conservative than the deterministic values provided by ASME code.
