PROCESS FOR COATING THE INTERNAL SURFACE OF HYDROTHERMOSANITARY PIPES, PARTICULARLY MADE OF ALUMINIUM, WITH RESINOUS PRODUCTS AND PIPES OBTAINED THEREWITH

摘要

A process is described to realize a film made of an adequate resinous material on the internal surface of metallic pipes, particularly those made of aluminium, to protect them and further allow for particular uses for which they could not be employed otherwise. These pipes are preferably applied in the hydrothermosanitary field.
