Abstract

Raccord pour tuyaux à relier bout à bout. Il comporte un manchon métallique 12 dont les extrémités sont évasées de manière à loger des joints en élastomère qui entourent étroitement les extrémités des tubes à relier. Des éléments suiveurs 16 sont montés sur les joints 14 en élastomère et peuvent être rapprochés l'un de l'autre par serrage d'écrous 18a sur des boulons 18. Au cours de cette opération, plusieurs mors 19, de forme à peu près triangulaire, sont serrés sur les extrémités des tuyaux. Domaine d'application : raccordement de tuyaux.End-to-end connection for pipes. It comprises a metal sleeve 12, the ends of which are flared so as to house elastomer seals which closely surround the ends of the tubes to be connected. Follower elements 16 are mounted on the elastomeric seals 14 and can be brought together by tightening nuts 18a on bolts 18. During this operation, several jaws 19, of roughly triangular shape , are clamped on the ends of the pipes. Area of application: pipe connection.
