Double-walled containment systems address environmental and safety concerns, providing total containment protection (120% of inner tank's capacity) and preventing foreign matter from entering the outer containment tank. They are most commonly used for demanding harsh chemical storage and handling applications such as bleaching agents, caustics and acids.
Tanks are available in 1.5 and 1.9 specific gravity in XLPE and HDLPE resin packages.
35 to 10,000 USG sizes are available, with the 275 to 500 USG models featuring molded-in forklift channels in the tank base. 550 USG and larger tank models have heavy duty molded-in tie down lugs and top-lifting eyelets to make handling easier and safer and also provide protection against the forces of seismic and wind. Tanks are available in both closed and open top styles up to 500 USG.
Bolted, threaded and hinged manways are available up to 24" diameter for systems over 500 USG. Bottom sidewall fittings are available on all sizes located at 0º, 90º, 180º & 270º with numerous location available for top fittings. Tanks can be customized with level indicators,leak detection, ladders, a variety of access lids, pre-engineered seismic hold-down systems, as well as insulation and heating. U-vent assemblies are also available to relieve stress from vacuum or pressure.
