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.

The Distributor Difference

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.

Four Engineering Pillars
PPC-01

Crosslinked Polyethylene (XLPE)

Covalent molecular bridges resist environmental stress cracking. Decades of service where standard HDPE fails in 12–36 months. ASTM D1998 compliant.

PPC-02

SAFE-Tank System

Tank-within-a-tank design providing 110% secondary containment in a single footprint. EPA SPCC compliant.

PPC-03

IMFO Outlet System

Integrally molded flanged outlet provides zero-heel gravity drainage and eliminates mechanical joint failures at the tank base.

PPC-04

OR-1000 System

Engineered antioxidant interior layer for heavy-duty oxidizing service. Required above 12.5% NaOCl, ferric chloride, and hydrogen peroxide.

FAQ

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.
