ABSTRACT:
A method for setting a protective coating on the inner wall of a tube includes providing a cylindrical sleeve, then setting on the outer surface of the sleeve a layer of a thermo fusible material, then machining the sleeve to provide it with an external diameter corresponding to the tube internal diameter, positioning the sleeve in the tube, and finally soldering the sleeve on the tube by applying heat.
