 Double Walled Chemical Tanks

SAFE-T
ANK® Systems
  Double-Wall Containment - Tank-in-a-tank

               

SAFE-Tank® is a “tank-within-a-tank” system that keeps contaminants from entering the interstitial area. These tanks provide secondary containment to avoid the damaging of equipment or property, loss of chemical, or injury to employees in the event of a spill.



  • Provides 110% secondary containment.
  • Will equalize the liquid and allow the chemical to be used until it is convenient to repair the tank.
  • Is ideal for chemicals like sulfuric acid that can have dangerous exothermic reactions to water.
  • Eliminates the expense, cost and maintenance of secondary concrete containment.
  • Minimizes the system’s footprint by providing secondary containment in a more compact way.
  • Adding a bellows transition fitting will maximize your SAFE-Tank® system's performance.
Specifically recommended when secondary containment is required for:

Sulfuric Acid  Sulfuric Acid                                      Hydrofluoric acid Hydrofluoric Acid

Hydrochloric (Muriatic) acid Hydrochloric Acid                               Hydrogen Peroxide Hydrogen Peroxide

Hydrofluorosilcic acid Hydrofluosilicic Acid                           Sodium Hydroxide (Caustic Soda) Sodium Hydroxide (Caustic Soda)

Sodium Hypochlorite (Bleach) Sodium Hypochlorite (Bleach)               Ferric, Alums & Polymers Ferrics, Alums & Polymers 

Specify HDXLPE poly tanks with OR-1000 for increased chemical resistance and tank longevity

stress and crack resistance

 
Flexible Connections
Polyethylene tanks expand and contract by design. This is one characteristic which gives PE its extraordinary chemical resitivity. Flexible connections are required, in the lower 1/3 of the tank wall, to increase tank longevity, operating efficiency and safety. (read more..)
Flexible PTFE connectors and tremor barriers

These flexible PTFE connectors and tremor barriers are designed to compensate for misalignment, absorb expansion and contraction, and isolate the vibration and shock that could damage a tank. Their low spring rate protects stress sensitive connections. Can be installed directly to the dome of the tank to overcome piping misalignment.

Flexible hose connectionFlexible hose connections isolate the tank from stresses and forces associated with pumps and piping. This connection is manufactured from Ultra High Molecular Weight hose which offers tremendous chemical resistance, two King nipples (barbed) and mechanically attached stainless steel bands securing the hose to the nipple.

A great solution for transitioning through secondary containment.
