PROCEDE DE MISE EN PLACE D'UN REVETEMENT DE PROTECTION SUR LA PAROI INTERNE D'UN TUBE, TUBE ET NOTAMMENT TUBE D'ARME REALISE SUIVANT CE PROCEDE

摘要

The invention concerns a method for setting a protective coating (4) on the inner wall of a tube (2). Said method is characterized in that it consists in producing a cylindrical bushing having a thickness not less than 1 mm, then in setting on the outer surface of said bushing a layer of a thermofusible material, then in machining the thus coated bushing to as to provide it with an external diameter equal to the tube internal diameter, positioning the bushing in the tube, and finally brazing the bushing on the tube by applying therein localized heating means while gradually moving it forward longitudinally from one end of the bushing to the other.
