Construction of a Steel Storage Tank
|
| Category: | Airport Improvements |
| Status: | Open |
|
| Internal wetted and vapor-space steel | Stripe coat + 2 coats immersion-grade epoxy lining; then UV topcoated | 20-30 mils |
|---|---|---|
| Exterior buried steel | Factory-applied 100% solids polyurethane/polyurea/hybrid or high-build buried- service epoxy | 70 mils minimum; 80 mils target |
| Exterior exposed steel | Epoxy primer + high-build epoxy + aliphatic polyurethane or polysiloxane | 10-14 mils |
| Grade transition band | Buried coating extended above grade, then UV topcoated | Same as buried system plus UV topcoat |
Coating Specifications:
Buried exterior steel surfaces shall receive a factory-applied, high-build dielectric coating system
suitable for permanent buried steel service without cathodic protection. Coating shall be applied
over a NACE surface profile as recommended by the coating manufacturer. All edges shall be
rounded, welds cleaned, and discontinuities removed before blasting.
The buried coating system shall be plural-component 100% solids polyurethane, polyurea,
polyurethane/polyurea hybrid, or 100% solids high-build epoxy rated by the manufacturer for
buried steel service. Minimum total dry film thickness shall be 70 mils / 1,750 m, with 80 mils /
2,000 m target.
All buried coated surfaces shall be holiday tested in accordance with NACE SP0188. No
holidays, pinholes, cracks, blisters, delamination, exposed steel, underfilm contamination, or
mechanically damaged coating shall be accepted. All repairs shall be made using the coating
manufacturer's written procedure and shall be retested before backfill. NACE SP0188 provides
procedures for high- and low-voltage holiday detection of new non-conductive coatings on
conductive substrates.
No backfill shall be placed until the buried coating has passed final holiday testing and visual
inspection. The first backfill lift against the tank shall be clean sand or selected fine granular
material free of sharp stone, slag, cinders, rubble, organic material, debris, or corrosive
contaminants. Coating shall be protected from damage during lifting, setting, shoring removal,
and backfilling.
