Thermal insulation and corrosion protection in petrochemical plants
In petrochemical plants insulation and corrosion protection are not two separate jobs — the same surface has to withstand the operating temperature, the chemical atmosphere and moisture, for years between turnarounds.
What it solves
Tanks, columns, exchangers and pipelines lose heat and hide corrosion under conventional lagging. A coating system — primer, thermal layer and topcoat — delivers insulation and steel protection in one, with no cavity for moisture to sit in.
Industry references
At a BP plant in Germany the system was applied through the contractor XERVON Oberflächentechnik GmbH, a specialist in industrial surface protection. For that kind of client documentation and repeatable application are a condition, not a recommendation.
High temperatures
For lines and equipment above 200 °C, high-temperature formulations are used with a primer of the same temperature class. The system is chosen by the highest operating temperature, not the average — short peaks are what defeats a wrongly selected coating.
Corrosion protection
For steel in an aggressive atmosphere there is a solvent-based zinc primer and a two-pack primer, depending on the substrate condition and the preparation that is feasible on site.
Important note
Thermal coatings marked NF carry no fire rating. Where fire resistance of a steel structure is required, intumescent coatings are used — see the Fire protection page.

Thermal insulating of BP plant XERVON Oberflächentechnik GmbH in Germany
At a BP plant with XERVON Oberflachentechnik GmbH, several hundred square metres of industrial process wall panels were coated with the C-COAT System (TIC 300HH) to save energy and provide safe-to-touch surfaces.
SUEZ Water Treatment Plant Steam Pipes by Brolton Group NSW
SUEZ requested a safe-to-touch feature for hot steam pipes (150-200C) in its water treatment plants to prevent staff skin burns; C-COAT protected staff and later showed an estimated 15-35% energy reduction.
