UL 142 DOUBLE WALL TANKS
Aboveground Storage Tanks (ASTs) are used to store a variety of liquids from petroleum based products to waste water. Because most ASTs store material that is flammable or combustible, the Federal government has enacted strict aboveground storage tank regulations to reduce or eliminate personnel injury or environmental contamination due to construction failure to overfilling during filling activities.
Design
Our storage tanks meet and exceed these standards offering secondary containment offered in 110% 125% and 150% with optional gauging and leak detection systems. All welding done in accordance with ASME standards by certified welders for the highest quality. Welding process for all seams are gas tungsten arch welding (GTAW) TIG welded for 100% penetration to prevent a welding failure.
Tanks are offered in maintenance free 304/316 stainless steel.
Coatings
All weather-exposed tank exteriors are prepared in accordance with SSPC SP-1 and NACE 1 Standards. Anchor profile verified with Testex Press-O-Film tape for maximum coating adhesion. Corrosion protection is provided by Sherman Williams high performance industrial quality performance marine coatings. Ferrous surfaces are coated with two-component polyamide-epoxy mastic applied to a dry film thickness (DFT) of 5 to 7 mils. Top coat is two-component acrylic aliphatic urethane applied to 2 to 3 mils DFT. Coatings are quality controlled checked with wet film thickness gauge and dry film thickness gauge after coatings are cured. Tanks will be labeled in accordance with OSHA & NFPA requirements. Custom colors and labeling is available upon request.
