Abstract

Tube métallique comportant un revêtement en plastique et un secteur d'arrêt pour une pièce mobile. L'invention concerne en particulier un tube métallique équipé d'un revêtement en plastique, en particulier en polytétrafluoréthylène, présentant un secteur faisant saillie dans la section de passage et destiné à retenir une pièce mobile disposée à l'intérieur du tube métallique à revêtement, en particulier la bille d'un clapet anti-retour, caractérisé par le fait que le secteur de retenue comporte au moins trois becs 7 à 10 formés à partir du revêtement en plastique 4, becs faisant saillie radialement vers l'intérieur, disposés sur le pourtour intérieur du tube et convergeant axialement l'un vers l'autre. Application au transport de fluides corrosifs par des tubes ou conduits.
