Poly Processing
SAFE-Tank double-wall containment, crosslinked polyethylene (XLPE) construction, IMFO outlet fittings, and OR-1000 rupture protection — 30+ years, 100+ LibertyCES-specified projects, zero specification failures.
What LibertyCES specifies from Poly Processing
Double-wall secondary containment — the outer tank fully contains the inner tank's entire volume as one integrated system. Crosslinked polyethylene (XLPE) resists environmental stress cracking (ESCR).
Outlet flange molded as part of the tank wall — removes the seam that's typically the first leak point on a bottom-outlet tank, and a sloped-bottom IMFO tank fully drains.
Engineered to arrest a tank failure before it becomes an uncontrolled release — a documented protection layer beyond the tank's base pressure/stress rating.
When a standard XLPE configuration doesn't fit a required footprint or structural load, lined-steel and custom fabrication covers the gap.
Frequently Asked Questions
What is a Poly Processing SAFE-Tank system?
A double-wall secondary containment tank where the outer tank fully contains the inner tank's entire volume, engineered as one integrated system rather than a tank-plus-berm afterthought.
What is XLPE and why does it matter for chemical storage tanks?
Crosslinked polyethylene — it resists environmental stress cracking (ESCR) better than standard HDPE under long-term chemical exposure and UV load, the specific failure mode ESCR-rated resin is engineered to avoid.
What does the IMFO outlet fitting do differently?
The outlet flange is molded as part of the tank wall itself rather than a separate bolted or welded bulkhead fitting, removing the seam that's typically the first leak point on a bottom-outlet tank.
