Thermal Spray Aluminium (TSA) inhibits general corrosion of carbon steels and protects austenitic stainless steels against pitting corrosion.
We have extensive experience in applying TSA coatings to chemical plant pipework components and equipment. In this process, the surface, properly prepared by grit blasting, is coated with pure aluminium in a 200-300 micron layer and then sealed with a silicone liquid containing aluminium pigments.
Result: effective corrosion protection even at elevated temperatures (300-500 °C) and extended corrosion life.
