Double Wall Tanks

Millinocket Fabrication and Machine’s custom double wall tanks are precision-machined and highly-engineered storage tanks that are capable of above-ground or below-ground storage. These double wall steel tanks are manufactured from high-grade steel where the main tank is surrounded by an outer steel wall that provides critical protection against spills or leaks. As a double wall tank manufacturer, we ensure that the insides of both walls are coated with an anti-corrosive zinc coating so that steel degradation due to corrosive chemicals is never a concern.

Essential Secondary Containment

]Our approach to designing and manufacturing double wall tanks starts with an overriding goal of ensuring the best possible secondary containment solution available on the market today. Whether it’s manufacturing cylindrical double wall tanks with a fixed or floating roof, a pressure tank to hold ammonia, chlorine, or other gasses, or a smaller horizontal double wall tank for above or below-ground storage, we have the capacity and know-how to manufacture any size or configuration you need.
