Abstract
L'invention concerne des capuchons de fermeture en matière plastique pour les extrémités de tubes métalliques. Sur des tubes 1 et 2 sont engagés des capuchons 3 et 4 de fermeture d'accouplement dont les corps 5 et 6 comportent des ouvertures 7 servant au dégazage des tubes. Ces ouvertures 7 sont conformées en languettes et les corps des capuchons 5, 6 comportent, sur leur face intérieure, une substance inhibitrice 9 contre la corrosion des surfaces intérieures des tubes, ladite substance étant contenue dans une capsule perforée 10 fixée aux parois intérieures des capuchons de fermeture. L'invention s'applique à la protection contre la salissure et la corrosion de la surface intérieure des tubes et aux éléments d'accouplement pour les extrémités des tubes pendant leur recouvrement par une surface d'enduction.The invention relates to plastic closure caps for the ends of metal pipes. Coupling closure caps 3 and 4 are engaged on tubes 1 and 2, the bodies 5 and 6 of which have openings 7 used for degassing the tubes. These openings 7 are shaped as tongues and the bodies of the caps 5, 6 comprise, on their inner face, an inhibiting substance 9 against the corrosion of the interior surfaces of the tubes, said substance being contained in a perforated capsule 10 fixed to the interior walls of the caps. closing. The invention applies to the protection against soiling and corrosion of the inner surface of the tubes and to the coupling elements for the ends of the tubes during their covering by a coating surface.
