Industrial corrosion protection
Industrial corrosion protection: TSA coatings and protection against corrosion under insulation (CUI).
We protect chemical, petrochemical and oil industry equipment, pipelines and tanks with Thermal Spray Aluminium (TSA). The coating is also effective against corrosion under insulation (CUI) caused by condensation, and provides protection at high operating temperatures.
What is corrosion under insulation (CUI)?
On insulated pipelines and tanks, moisture getting under the insulation and constant condensation corrode the steel unnoticed. TSA coating inhibits general corrosion of carbon steel and protects austenitic stainless steel against pitting corrosion.
How the TSA coating is applied
- Grit blasting: a clean, rough surface for adhesion.
- Metal spraying: 200–300 µm of pure aluminium.
- Sealing with an aluminium-pigmented silicone sealer.
The result is effective corrosion protection even at 300–500 °C, and a longer corrosion lifetime.
Coatings for special requirements
Depending on the job, we also spray zinc, aluminium, Zn/Al 85/15 alloy, copper and special steel alloys (Inconel, Hastelloy, chromium-nickel-molybdenum-manganese, tungsten). The metal layer can be thicker than 250–350 µm, and we also produce coatings for equipment operating at 400–600 °C.

Frequently asked questions
Up to what temperature does TSA protect?
Silicone-sealed TSA coating is effective even at 300–500 °C. With special coatings, we also protect equipment operating at 400–600 °C.
Can it be used on stainless steel?
Yes. TSA protects austenitic stainless steel against pitting corrosion.
Do you work on site?
Yes, provided the technical conditions for the work can be met. We can bring the technology to your site.
Which standards do you work to?
Thermal metal spraying is covered by EN ISO 2063, surface preparation by EN ISO 8503 and paint systems by EN ISO 12944.
