On-site anti-corrosion coating with HVAS technology
Advanced and immediate protection for Oil & Gas equipment directly on site. Flame Spray offers an on-site anti-corrosion coating service based on HVAS (High Velocity Arc Spraying) technology, ideal for distillation columns, heat exchangers and refinery tanks. This HVAS coating refinery equipment solution allows the application of high-performance anti-corrosion metal coatings without dismantling the plants, minimizing downtime and operating costs.
Our specialized teams operate globally directly on the field, ensuring operational continuity and rapid interventions at your production site.

Benefits of On-Site HVAS
Reduce costs and downtime
Applying the coating directly on site eliminates the need to move bulky components to external workshops, thus avoiding high logistics costs. This approach allows to significantly reduce plant downtime, speeding up the recovery of critical equipment. The result is a more efficient management of extraordinary maintenance and greater operational continuity over time.
High resistance to corrosion and temperature
HVAS coatings provide excellent protection against aggressive chemicals such as acids, salts and hydrocarbons found in refinery environments. The use of nickel-based superalloys, such as NiCrMo, ensures stable performance up to 800°C. This ensures a reliable barrier against corrosion, erosion and thermal stress, even in the most extreme operating conditions.
Rapid high thickness deposition
HVAS technology allows to quickly obtain high coating thicknesses on large surfaces, with reduced execution times compared to other processes. The result is a compact and resistant layer that extends the life of the treated components. This makes anti-corrosion interventions faster, reducing the impact of stops and improving overall efficiency.
Low thermal impact on the substrate
During HVAS spraying, the heat transferred to the component is minimal, preserving the structure and shape of the base material. The low temperature of the substrate avoids deformations and does not require subsequent heat treatments. This makes the process safe for sensitive components, avoiding metallurgical alterations and ensuring optimal mechanical integrity.
Versatility and on-site application
The compact and transportable HVAS system allows interventions directly at the plant, even in narrow or difficult to access spaces. It is possible to coat internal and external surfaces of columns, tanks and exchangers on site, without dismantling. This provides protection comparable to that of a workshop, but with a lower operational impact and simplified logistics.
