Ceramic protection for heat
exchangers technology

Concept

Innovative solutions based on high performance ceramic coatings. Anticorrosive and antifouling properties provide long term and reliable protection to industrial metal components (tubes and fluid passage areas) working on severe environments.

Silica-based ceramic coating could be applied inside and outside of long and narrow metallic tubes (carbon steel, stainless steel, high alloys, etc.) getting reliable and combinative properties:

              • > Glassy Surfaces with very low roughness = little or no adherence of fouling.
              • > Water Pressure Cleaning Resistance up to 2,300 bar. (36,260,00 psi)
                • > Chemical Resistance:
          • - Hot Cold Acids – Except HF
          • :: Sulfur and Sulfate
            • :: Nitric
            • :: Chloride
          • - Hot & Cold Alkalis – Except concentrate (OH)Na & (OH)K.
          • - Water Hot & Steam.
          • - High concentration Salt Water.

This innovative technology has been developed side by side with KERACOAT company www.kera-coat.com, CIDETEC spinoff focused on tailor made ceramic formulations and further implemented in long and narrow metallic tubes by TUBACOAT tubacoat.com (a subsidiary company of the Tubacex Group). This technological approach gives and efficient and environmental friendly solution, protecting components from critical degradation and keeping the energetic efficiency by avoiding fouling and corrosion phenomena.
