    Tank types we provide

    • Above-ground steel (UL-142): Single- or double-wall with integral containment, fire-rated options, ladders, gauges, and fill/return headers.

    • Underground fiberglass (UL-58/UL-1746): Corrosion-resistant with double-wall construction and interstitial monitoring.

    • Specialty configurations: Day tanks, skid-mounted systems, pump/control skids, and multi-compartment layouts for blended or multiple oils.

    Selecting the right tank

    • Capacity & space: Match delivery frequency and burn/usage rates to minimize short-cycling and truck stops.

    • Containment strategy: Double-wall vs. dike/curb based on site constraints and permitting.

    • Product & viscosity: Heat tracing, insulation, or mixers for heavy oils; filtration and water draw-off for reliability.

    • Monitoring & automation: Level transmitters, overfill alarms, leak detection, and remote telemetry for audits and operations.

    • Future serviceability: Access for inspection, cleaning, and eventual change-out without disrupting production.

    Installation & compliance

    • Engineered pads, anchoring, and seismic/wind restraint

    • Proper vent sizing, emergency/normal vents, and vapor routing

    • Piping to current standards (fill, suction, return, and overfill prevention)

    • Labeled valves, spill containers, and lockable fills

    • Start-up documentation, drawings, and operator training

    Maintenance & testing

    • External and internal inspections, thickness readings, and coating rehab

    • Interstitial and sump checks, electronic leak detection calibration

    • Water bottom removal, filtration, and polishing to protect burners and engines

    • Cathodic protection surveys and rectifier checks (UG tanks)

    Arizona considerations we solve

    • Heat & UV: Coatings and shade strategies to reduce thermal cycling and extend paint life.

    • Dust & monsoon: Weatherproof vents, screened breathers, and elevated appurtenances to keep water and debris out.

    • Hard access sites: Modular and skid systems for fast installs with minimal crane time.

    FAQs

    What’s the difference between above-ground and underground tanks?
    Above-ground tanks are easier to inspect and service and often lower cost to install; underground tanks save space and visual impact but require corrosion control and additional monitoring.

    Do I need double-wall or secondary containment?
    Most sites benefit from double-wall construction or a properly sized dike/curb. The choice depends on local code, space, and risk tolerance—we’ll recommend the most compliant, cost-effective path.

    How long do oil tanks last in Arizona?
    With proper coatings (AG) or corrosion protection (UG) and routine inspections, typical service life ranges 20–30+ years. Heat and UV exposure make maintenance discipline especially important.

    Can you replace an existing tank without long downtime?
    Yes. We stage temporary tanks or fuel polishing, prefabricate piping, and sequence tie-ins during low-load windows to keep operations running.

    What permits or inspections are required?
    Requirements vary by jurisdiction and tank size. We coordinate permits, PE drawings where needed, and commissioning tests, then provide as-built documentation for your records.
