Process for manufacturing copper conduits for air conditioning systems with improved anti-corrosive performance

Abstract

A continuous process for producing an air conditioning conduit is provided. The continuous process involves unwinding a copper tube from at least one coil and straightening the copper tube, cleaning the copper tube by plasma treatment, heating the copper tube to complete the cleaning of the copper tube, applying at least one adhesive on an outer surface of the copper tube, applying at least one polyamide anti-corrosion barrier layer over the at least one adhesive, cooling the copper tube coated with the at least one adhesive and the at least one polyamide anti-corrosion barrier layer, and applying around the coated and cooled copper tube at least one insulation layer made of closed-cell insulation material, thus obtaining the air conditioning conduit. The continuous process has the advantages of producing an air conditioning conduit that counteracts the phenomenon of formicary corrosion.
