Annealed Copper Tubes PVC Coated – Flexible, Insulated & Corrosion-Protected Solution
Annealed copper tubes PVC coated are widely used in modern industrial and residential applications where flexibility, corrosion resistance and external protection are critical. These tubes combine the natural advantages of annealed copper with an additional PVC coating layer that enhances durability and safety in demanding environments.
From HVAC and refrigeration systems to gas piping and plumbing installations, annealed copper tubes PVC coated provide reliable performance, easy installation and long service life.
What are Annealed Copper Tubes PVC Coated?
Annealed copper tubes PVC coated are soft copper tubes that have undergone an annealing process to improve flexibility and are further coated with a protective polyvinyl chloride (PVC) layer. This coating acts as an insulating and protective barrier against moisture, chemicals and mechanical damage.
These tubes are typically supplied in coil form, allowing easy bending and installation without the need for extensive fittings.
