SAFE-Tank® System

Secondary containment: SAFE-Tank® if concrete containment is not available.
Alternative: PPC secondary containment basis or other secondary containment suitable for chemical, of adequate size for use
Used in the production of aluminum, fluorocarbons and gasoline and for applications like glass etching and uranium processing, hydrofluoric acid is an extremely dangerous chemical that must be handled with the utmost care.
The extreme nature of this chemical calls for superior structural integrity – the level of integrity Poly Processing is known for.
When people’s lives are at risk, you can take no chances. You need a system that goes above and beyond to prevent contact with this corrosive acid. That system starts with a crosslinked polyethylene tank. XLPE is a thermoset resin that gives customers 20 times the environmental stress-crack resistance, 10 times the molecular weight and 5 times the impact and tensile strength of HDPE. This system carries a warranty for a full five years.
A SAFE-Tank® can help reduce health and environmental concerns due to closed containment of hydrofluoric acid.
If a SAFE-Tank® is not a possibility, an IMFO® flange can be used to reduce hands-on maintenance, thereby reducing the risk to your employees.
Chemical | Resin Type | Specific Gravity Rating | Fitting Material | Gasket Material | Bolt Material |
---|---|---|---|---|---|
Hydrofluoric Acid | XLPE | 1.9 | PP | Viton® | C-276 |
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 basis or other secondary containment suitable for chemical, of adequate size for use
Fittings: 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.
IMFO® Vertical Flat Bottom of XLPE:
230–13,650 gallons
1.9 spg rating
Non -IMFO® alternatives :
SAFE-Tank® XLPE:
55–8,700 gallons
1.9 spg rating for primary tank
Spg ratings for secondary tanks ≥ 3,000 gallons may be equal to or 1 less spg than primary tank.
All other tank sizes must equal primary tank spg rating.
Standard Vertical Flat Bottom XLPE:
30–13,650 gallons
Alternative secondary containment: PPC secondary containment basin or other secondary containment suitable for hydrofluoric acid, of adequate size for use
Plumbing: Requires use of flexible connections with fittings on lower third of sidewall. See Fittings & Accessories for flexible connections options.
Venting: See Venting Chart
Foundation: PPC IMFO® tank pad or smooth concrete, asphalt or steel foundation designed to accommodate IMFO®, SAFE-Tank® or vertical tank
Temperature: Product should not exceed 100°F at delivery or during storage to maintain ASTM D1998 design parameters.
Lid: Fume-tight manway cover to manage release of chemical gases
Options: Restraint systems for wind and seismic, level gauges, ladders, heating pads, insulation, mixer mounts and engineering stamp
