Archco 450™ Tank Lining Project – South Texas
Industrial Coatings & Linings
|South Texas, USA
Denso North America launched their Archco 450™ Lining System to compliment the full range of corrosion control protection products and systems that they already offer. The Archco 450 system focuses on providing corrosion protection for internal and external storage tanks.
A large oil and gas company in South Texas had a problem with internal tank corrosion after the pre-existing lining had failed due to old age. Archco 450 was chosen as the tank lining coating due to the excellent reputation for quality products and field service that Denso provides.
The project consisted of two open top/internal floater tanks with the sidewalls coated with Archco 400 high solids epoxy primer and then over coated with Archco 450, 100% solids epoxy, glass flaked filled lining.
All coatings were sprayed with a 68:1 single leg airless unit. The Archco 450 was sprayed at 25 to 30 mils in one coat. The coating was applied prior to the insulation of a new internal floating roof.
The Archco 450 System will provide the tank chemical resistance, plus the added benefit of the glass filled lining to withstand the abrasion of the floating roof seal, rubbing up and down, as the tank is filled and emptied. The tank floor linings will be installed after the insulation of the floating roof and will also be protected with the Archco 450 System. The owners can expect 25+ years of internal corrosion protection.
