Poly Processing Company:
The LibertyCES
XLPE Standard
We do not just distribute tanks — we engineer complete chemical storage systems. For over 30 years, LibertyCES has specified Poly Processing crosslinked polyethylene (XLPE) for the most aggressive oxidizing environments in municipal and industrial water treatment.
Precision Specification,
Not Catalog Ordering
Anyone can order a poly tank from a catalog. The engineering reality is that most chemical tank failures are specification failures, not equipment failures. The wrong wall thickness for a given temperature profile. Incompatible metal fittings introducing iron contamination into sodium hypochlorite. No secondary containment accounting for facility layout constraints.
When a facility procures Poly Processing equipment through LibertyCES, they receive a comprehensive material compatibility review, fitting specification, and CAD-level system integration design — before a single purchase order is issued.
-
Complete Fluid Dynamics Evaluation Analysis of fill temperatures, hydraulic pressure, UV exposure conditions, and specific gravity across the full operating range.
-
Exacting Fitting Specification — PVC/CPVC Only No incompatible metals. No galvanized steel, brass, or aluminum. Every fitting specified by material, schedule, and flange rating for the specific chemical service.
-
EPA SPCC Secondary Containment Compliance Seamless integration with EPA 40 CFR Part 112 Spill Prevention, Control, and Countermeasure requirements — designed into the system architecture from day one.
The Technologies That Eliminate Failure Modes
Four engineering pillars define Poly Processing's dominance in sodium hypochlorite and oxidizing chemical storage. LibertyCES specifies all four as a system — never in isolation.
Crosslinked Polyethylene (XLPE)
Covalent molecular bridges between polymer chains resist the environmental stress cracking that destroys standard linear HDPE in oxidizing chemical service. Where HDPE fails in 12–36 months, XLPE provides decades of service life under the same chemical loading.
ASTM D1998 CompliantSAFE-Tank System
A tank-within-a-tank design providing 110-percent secondary containment in a single footprint. Eliminates the need for open concrete basins, reduces civil construction costs, and meets EPA SPCC requirements without excavation or basin lining.
EPA SPCC CompliantIMFO Outlet System
The Integrally Molded Flanged Outlet is molecularly continuous with the tank wall — one piece, not bolted through. Achieves true zero-heel gravity drainage and eliminates the mechanical joint at the tank base — the most common catastrophic leak point.
Zero-Heel DrainageOR-1000 System
An engineered antioxidant interior layer that acts as a sacrificial barrier in heavy-duty oxidizing service. Required by LibertyCES for all sodium hypochlorite above 12.5% concentration, ferric chloride, and hydrogen peroxide applications.
Oxidizer-Rated Interior
From Bare Tank to Fully Commissioned Feed Skid
LibertyCES does not deliver a tank and walk away. The Poly Processing vessel is the foundation — the complete chemical delivery system is the product. Every commissioning engagement covers the full operational loop from storage to point-of-dosage.
The field installation shown here demonstrates the integration depth LibertyCES brings to every sodium hypochlorite chemical feed system: IMFO outlet transitioning directly into the rigid Schedule 80 CPVC manifold, magnetic level gauge for safe inventory monitoring, and a diaphragm metering pump mounted on the SAFE-Tank containment tray with secondary catch capacity.

XLPE NaOCl Specification Sheet
Complete technical specification document covering XLPE material properties, SAFE-Tank sizing methodology, IMFO outlet torque specifications, OR-1000 service requirements, fitting compatibility matrices, and EPA SPCC secondary containment calculations for sodium hypochlorite storage applications.
Specified for Critical Infrastructure
LibertyCES mandates Poly Processing XLPE equipment for every application where oxidizing chemical concentration, operating temperature, or regulatory compliance requirements exceed the capability of standard HDPE or fiberglass alternatives.
Municipal Water Treatment
Primary sodium hypochlorite disinfection storage and feed systems for surface water and groundwater treatment facilities serving potable water to the public.
Wastewater Disinfection
Effluent disinfection systems for municipal wastewater treatment plants operating under NPDES discharge permits. Sodium hypochlorite and sodium bisulfite dual-tank configurations.
Industrial Process Water
Cooling tower biocide systems, boiler feedwater chemical treatment, and process water pH adjustment for manufacturing and industrial facilities nationwide.
Food Processing CIP Sanitation
Clean-in-Place (CIP) chemical storage for food and beverage processing facilities. FDA-compliant XLPE formulations for direct food contact chemical storage applications.
Protecting Your Capital Expenditure
Standard HDPE tanks in sodium hypochlorite service fail in 12 to 36 months. The tank itself is the smallest line item in that failure. The total exposure per incident runs $50,000 to $250,000 when factoring in emergency replacement procurement, downtime at the treatment plant, regulatory penalty exposure, and environmental remediation if secondary containment was not properly integrated.
A properly specified Poly Processing XLPE system — with SAFE-Tank secondary containment, IMFO gravity drainage, and OR-1000 oxidizer barrier — does not fail in 36 months. It provides decades of service life on the same chemical loading that destroys HDPE.
The capital cost difference between an HDPE tank and a Poly Processing XLPE system is recovered in the first averted failure event. The compounding value across a 20-year facility lifecycle makes the specification decision straightforward. Review the case study data for documented field outcomes.
| 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 |
Secure Your Poly Processing
Specification
Do not guess on your hypochlorite or oxidizing chemical specification. The difference between a 14-month HDPE tank failure and a 20-year Poly Processing XLPE installation is not product quality — it is specification precision. That precision requires field experience.
James Riggins has specified Poly Processing XLPE systems across municipal water treatment facilities, industrial wastewater plants, and food processing CIP operations for over 30 years. When you call LibertyCES, you reach James — not a sales rep, not a call center. Bring your fluid type, concentration, volume, and operating temperature and you will leave the call with a complete specification.
