Abstract

Presse hydraulique destinée à la mise en pression intérieure de corps cylindriques que l'on désire par exemple éprouver, fretter, ou expanser. Elle comporte une enveloppe cylindrique extérieure 12 constituée de plusieurs morceaux 34, 35, 36 articulés de manière à permettre son ouverture. La portion inférieure fixe 34 est par ailleurs avantageusement munie de berceaux articulés cintrés permettant de supporter et de centrer le corps cylindrique à soumettre à la pression. L'invention est applicable aux tubes utilisés dans les industries nucléaire, pétrolière ou gazière.
