Double Wall Storage Tanks

High-quality Double Wall Storage Tanks

Our double wall tanks design

ACO’s durable double wall tanks consist of an inner tank and a secondary outer tank. The outer tank has a capacity 120% greater than the inner tank, serving as a containment measure in case of spills. The dome of the inner tank overlaps the sidewalls of the outer tank, preventing debris, rain, and snow from entering the containment.

Superior Construction and Material

Wide Range of Capacities and Specifications

Customization and Optional Accessories

Our seamless, one-piece double wall tanks are constructed using high-grade HDPE or XHDPE/XLPE polyethylene.
These tanks exhibit exceptional resistance to chemical erosion, outperforming mild steel, stainless steel, or FDP alternatives. Manufactured to ASTM specifications, our tanks are rugged, durable, and stabilized against damage caused by the sun’s ultraviolet radiation.
They are also designed to withstand low-temperature impacts, making them suitable for cold storage areas.

ACO offers a wide selection of double wall tanks with different capacities and specifications to cater to various liquid densities (specific gravities). Our tanks are suitable for storing and transporting liquids with specific gravities of less than 1.5, less than 1.9, and less than 2.2.
All our double wall tanks come with upper fitting flats as standard, while larger tanks include lifting lugs and molded lower fitting flats to accommodate a sturdy bottom outlet (optional).

ACO’s closed top double wall storage tanks provide versatility and can be customized to meet specific requirements. We offer an extensive range of optional accessories, including various fittings and manway lids, to ensure compatibility with your specific needs.

Importance of Double Wall Tanks

Double wall tanks provide an ideal solution for the storage of corrosive, environmentally hazardous, and dangerous substances that could pose risks to workers’ health, environmental damage, and public safety in the event of spillage. Local and federal government regulations increasingly require the use of double-walled tanks, especially during the transportation of hazardous products and for underground storage purposes.
