The LibertyCES XLPE Standard
Authorized Poly Processing Distributor, specializing in spec-first XLPE chemical storage engineering.
LibertyCES has engineered complete chemical storage systems for over 30 years, specifying Poly Processing crosslinked polyethylene (XLPE) across 100+ municipal and industrial projects with zero specification failures. James Riggins' field record demonstrates that proper specification — not just equipment quality — prevents tank failures.
Precision Specification, Not Catalog Ordering
Most chemical tank failures stem from specification errors rather than equipment defects. LibertyCES provides complete fluid dynamics evaluation (fill temperatures, hydraulic pressure, UV exposure, specific gravity), exacting fitting specification (PVC/CPVC only, no incompatible metals), and EPA SPCC secondary containment compliance designed into system architecture.
Crosslinked Polyethylene (XLPE)
Covalent molecular bridges resist environmental stress cracking. Decades of service where standard HDPE fails in 12–36 months. ASTM D1998 compliant.
SAFE-Tank System
Tank-within-a-tank design providing 110% secondary containment in a single footprint. EPA SPCC compliant.
IMFO Outlet System
Integrally molded flanged outlet provides zero-heel gravity drainage and eliminates mechanical joint failures at the tank base.
OR-1000 System
Engineered antioxidant interior layer for heavy-duty oxidizing service. Required above 12.5% NaOCl, ferric chloride, and hydrogen peroxide.
LibertyCES delivers fully commissioned feed skids, not bare tanks:
- Poly Processing SAFE-Tank (XLPE/OR-1000) with IMFO outlet
- Schedule 80 CPVC rigid manifold
- Magnetic level gauge (non-contact monitoring)
- Diaphragm metering pump mounted on containment tray
- Secondary containment tray integrated with SAFE-Tank basin
| Cost Factor | Standard HDPE | Poly Processing XLPE |
|---|---|---|
| Typical service life (NaOCl) | 12–36 months | 20+ years |
| Secondary containment | Separate civil basin required | Integrated — SAFE-Tank |
| Base fitting leak risk | High — mechanical joint | Zero — IMFO molded |
| Emergency replacement cost | $50K–$250K per incident | $0 — no failure events |
| Regulatory penalty exposure | High — containment gap | Low — SPCC compliant |
| 20-year lifecycle cost | 3–6 replacement cycles | Single capital investment |

Frequently Asked Questions
What is the difference between XLPE and standard HDPE chemical storage tanks?
Crosslinked polyethylene (XLPE) forms covalent molecular bridges, increasing resistance to environmental stress cracking. HDPE typically fails in 12–36 months under sodium hypochlorite exposure; XLPE provides decades of service. LibertyCES specifies XLPE exclusively for oxidizing chemical applications — HDPE is unapproved on any hypochlorite specification.
What is the Poly Processing SAFE-Tank system and do I need it?
The SAFE-Tank provides 110% secondary containment in a compact footprint, eliminating separate concrete basins. LibertyCES mandates it for all high-volume sodium hypochlorite and oxidizing chemical storage where EPA SPCC compliance is required.
What is an IMFO outlet and why does LibertyCES require it?
The Integrally Molded Flanged Outlet (IMFO) is a drain flange manufactured as molecularly continuous with the tank wall — one piece rather than bolted. This eliminates the most common catastrophic leak point and enables true zero-heel drainage.
When is OR-1000 required and what does it protect against?
OR-1000 is an engineered antioxidant interior layer acting as a sacrificial barrier. LibertyCES requires it for sodium hypochlorite above 12.5%, ferric chloride, and hydrogen peroxide. Below 12.5% hypochlorite, standard XLPE may apply based on temperature profile.
How does LibertyCES support Poly Processing procurement from spec through commissioning?
Every procurement includes material compatibility review, fitting specification, secondary containment design, and CAD-level system integration. Post-delivery commissioning covers IMFO torque verification, pump calibration, level gauge setup, and initial dosing rate verification.
