Finned Tube Corrosion protection

Finned tube heat exchangers are often the first choice in power plants, offshore rigs and heavy industries. This type of finned tube bundles are known for the high quality but sometimes need extra protection in corrosive environments. To seal of the vulnerable metals from corrosive elements Blygold developed special application procedures and coatings for these spiral tubes bundles.

Coatings can be applied to L-foot, embedded and  extruded fin tubes. Finned tubes can be coated before bundle assembly but also already assembled bundles can be protected due to special Blygold spray procedures that ensure full coverage even in the middle of these thick and complex elements.

All Blygold coating treatments  have been tested for effect on heat transfer and pressure drop, corrosion and chemical  resistance. Customers are assured that coated bundles will be ready for long lasting performance .  Even for heat recovery coils in hot exhaust gasses Blygold is able to provide a solution to protect aluminium against the harsh conditions.
