SAFE-Tank® System

Secondary containment: SAFE-Tank® if concrete containment is not available.
Alternative: PPC secondary containment basin or other secondary containment suitable for chemical, of adequate size for use.
Available in a variety of concentrations, hydrogen peroxide is used as an oxidizing agent in textile, paper and fur processing. It is also used as a plasticizer, a polymerization catalyst and a water and sewage treatment chemical.
It poses a number of challenges when it comes to storage:
For concentrations of hydrogen peroxide that are below 50%, high-density crosslinked polyethylene is a smart option.
If there is a chance that hydrogen peroxide has escaped from its storage system, evacuation is mandatory, since explosion could occur. It’s imperative that an environment be made as leak-free as possible. Poly Processing’s crosslinked polyethylene helps ensure that, by providing a high-strength storage option for hydrogen peroxide.
The SAFE-Tank® system offers tank-within-a-tank protection for secondary containment.
And if secondary containment is already provided for the tank, Poly Processing recommends the IMFO® tank system to provide complete drainage without entering the vessel shell, helping personnel avoid contact with this strong irritant.
Chemical | Resin Type | Specific Gravity Rating | Fitting Material | Gasket Material | Bolt Material |
---|---|---|---|---|---|
Hydrogen Peroxide | XLPE | 1.9 | PVC/CPVC | Viton® | 316SS |
Tank options include:
High-density crosslinked polyethylene (XLPE) construction for maximum strength
OR-1000™ antioxidant inner surface
Integrally Molded Flanged Outlet (IMFO®) for complete drainage
SAFE-Tank® design for "tank-within-a-tank" protection
Secondary containment: SAFE-Tank® if concrete containment is not available.
Alternative: PPC secondary containment basin or other secondary containment suitable for chemical, of adequate size for use.
IMFO® eliminates the need for confined space entry.
Plumbing: Requires flexible connections to allow for lateral and vertical tank contraction and expansion, and to reduce vibration stress.
Venting: SAFE-Surge® manway cover is recommended on pneumatically loaded systems to support tank longevity.
NOTE: Use only flanged connections with hydrogen peroxide. Threaded fittings should be avoided!
