UL-142 Double Wall Horizontal Skid Tanks

UL-142 double wall horizontal skid tanks are built for dependable aboveground fuel storage where safety, containment, and efficient site layout matter. Mills Equipment offers standard sizes from 150 to 16,350 gallons, along with custom sizes on request, giving businesses, farms, and facilities a practical way to store fuel in a compact horizontal format.

Why Choose A Double Wall Horizontal Skid Tank

A double-wall design adds an outer protective shell around the inner tank, creating built-in secondary containment that helps prevent leaks from reaching the ground and supports easier compliance for many long-term installations. If you are evaluating alternatives, our guide to comparing single-wall vs. double-wall fuel tanks can help you choose the design that best fits your operation, footprint, and risk profile.

Applications And Configuration Options

These UL-142 skid tanks are a strong fit for diesel and gasoline storage, construction sites, equipment yards, farms, and commercial fueling operations. Their skid-mounted format works well where durable aboveground storage is needed on active job sites or in space-conscious layouts. To compare common capacities and footprints, review our tank capacity charts, and for tighter-access projects, see Top 5 compact fuel tanks for urban construction sites. Mills Equipment also offers custom sizing and standard white or tan paint options to match project requirements.

Site Planning And Compliance

UL-142 tanks are widely used for general-purpose aboveground fuel storage, but the right setup still depends on fuel type, location, venting, overfill protection, and local requirements. If your site involves added fire exposure or special protection needs, review UL-2085 vs. UL-142: Which Certification Is Right for Your Tank?. Before installation, use our UL-142 labeling, vents, and overfill checklist and best practices for new petroleum tank installations to plan for safe placement, spill prevention, and long-term performance.
