摘要

Process for manufacturing a metal tube coated internally by a tube of polymeric material and tube thus manufactured.; Process for manufacturing a metal tube coated internally with a tube of polymeric material for use in any installation or system requiring high corrosion resistance and pressure, and tube thus manufactured, said process comprising cooling a tube of polymeric material to collapse and introduce it inside a metal tube pretreated and coated with epoxy paint. The metallic tube should have an inner diameter slightly smaller than the outer diameter of the polymer tube, so that the reacquire room temperature, the polymer tube and introduced into the metal is strongly fitted and bonded to form the lining of metallic pipe.
