Abstract

L'invention se rapporte au service technique (à la vérification) et à l'exploitation de cuves et pipelines sous pression. On considère que les cuves ou les pipelines ont passé les tests hydrauliques et pneumatiques si lors des tests et après la vérification des résultats on n'a pas décelé de fuites et/ou de ruptures de métal, si pendant la retenue la tension n'est pas sortie des limites prédéterminées et si aucune déformation résiduelle n'a été décelée après la fin des tests. Le régime des tests est choisi de manière à ce que la taille des fissures faisant partie de la famille des fissures de taille critique, qui correspond au régime des tests, soit inférieure à la taille des fissures de la taille critique qui correspondent au régime d'exploitation normal. La périodicité des tests est choisie de manière à ce que le temps entre les tests hydrauliques et pneumatiques ne dépasse pas le temps d'augmentation des dimensions des fissures faisant partie de la famille des fissures de taille critique, qui correspondent au régime des tests hydrauliques et pneumatiques, jusqu'à la taille des fissures faisant partie de la famille des fissures de taille critique qui correspondent au régime d'exploitation normal.
