Excellent corrosion and oxidation resistance
The corrosive and oxidising properties of the service media used in the stainless steel pickling lines at Outokumpu Oy Polarit in Tornio, Finland,made finding a process heat exchanger a challenge.
DATE 2023-11-28Mixtures of nitric acid and hydrofluoric acid at temperatures up to 60°C (140°F) ruled out the use of metallic materials and normal synthetic resin impregnated graphite.
Therefore, Outokumpu decided to purchase Alfa Laval’s graphite plate heat exchanger in Diabon F100, a fluoroplastic (PVDF) bonded graphite composite material known for its corrosion and oxidation resistance.
Products
When corrosion is an issue use the DIABON® range of plate heat exchangers. Indestructible even for the toughest media.
Benefits
- Excellent corrosion resistance
- Outstanding heat transfer properties
- Minimal plastic deformation. The fluoroplastic material maintains its shape even under pressure
- Impermeability. The material is absolutely impermeable to most types of fluid
