Abstract (en)
[origin: US4311189A] Exchanger which incorporates a casing in which the heat carried by a primary fluid is transferred to a secondary fluid so as to heat the latter, the secondary fluid circulating in the tubes, whose opposite ends issue into tubular supply and discharge mains located externally of the exchanger casing and surrounding the latter at least partly, wherein each of the tubes comprises two access devices each sealed by a removable plug, while each of the access devices is located in a part of the tube positioned between the exchanger casing and the corresponding main. The present exchanger is intended more particularly for the transfer of heat between two circuits of a nuclear power station.
Abstract (fr)
L'invention se rapporte à un échangeur de chaleur comportant une enveloppe (110) et des tubes (130) qui débouchent dans des collecteurs tubulaires (138) disposés à l'extérieur de l'enveloppe (110). Afin de permettre d'effectuer les contrôles et les mesures nécessaires dans chacun des tubes (130), un dispositif d'accès (146) est prévu dans chaque partie de tube disposée entre l'enveloppe (110) de l'échangeur et le collecteur (138) correspondant. L'invention s'applique notamment aux générateurs de vapeur équipant les réacteurs nucléaires.
