METHOD FOR SETTING A PROTECTIVE COATING ON THE INNER WALL OF A TUBE, TUBE AND IN PARTICULAR WEAPON TUBE OBTAINED BY SAID METHOD

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.
