VaporKote is currently aluminizing a large quantity of 1.5 inch diameter heat exchanger tubing to prevent high temperature corrosion. Both the inside and outside of the tubes were aluminized for this application via vapor deposition to ensure all surfaces were protected. The tubes shown above are loaded in a retort packed with our proprietary aluminum powder mix. This retort is then sealed for a high temperature furnace run where aluminizing takes place. The result is a tube with enhanced surface properties that can now resist the corrosion. aluminized heat exchanger tubing is very cost effective and helps increase tubing life.
