Title (EN) TIGHTNESS TESTING OF LARGE VESSELS OR THE LIKE
(FR) ESSAI D"ETANCHEITE DE GRANDS CONTENEURS OU AUTRES
Abstract: front page image
(EN)A method and a device for testing the tightness of large vessels (T) in a quick and reliable way. The vessel is filled with liquid under pressure. The liquid pressure unambiguously influences the pressure in a closed gas circuit (R) via a pressure transferring device, e.g. a diaphragm box (M1). To establish a possible leakage in the vessel (T), a pressure reduction in the gas circuit is detected, e.g. by means of a differential pressure sensor (M2).
(FR)Procede et dispositif d"essai de l"etancheite de grands conteneurs (T) de maniere rapide et fiable. Le conteneur est rempli d"un liquide sous pression. La pression du liquide influence sans ambiguite la pression dans un circuit ferme de gaz (R) via un dispositif de transfert de pression, par exemple une boite a diaphragme (M1). Pour detecter une fuite possible dans le conteneur (T), une reduction de la pression dans le circuit de gaz est detectee, p. ex. a l"aide d"un detecteur de pression differentiel (M2).
