Why Vertical Cylindrical — and Why Specs Matter
Verticals deliver the industry’s best cost per gallon — but only when they’re spec’d right. Too thin and you get base bulge; wrong resin and chemicals attack the wall; fittings in the wrong place and compliance is gone on day one.
Extrusion-wound cylinder for uniform wall — eliminates “elephant foot” failures.
Resin temp bands: HDPE ≈ 120°F, PP ≈ 180–200°F.
ASTM D1998 builds with engineered wall logic & stress limits.
NSF/ANSI 61 potable options for water & process liquids.
Siphon / maximum drain kits for near-total bottom evacuation.
Molded tie-downs & lift lugs with seismic/wind restraints available.

SG rating+Resin Comparison — Choose the Right Build
HDPE = Everyday Workhorse
PP = High-Temp Specialist
XLPE = Compliance Tank
| Resin | Temp Band | Chemical Compatibility | Typical Applications |
|---|---|---|---|
| HDPE Best Value | Up to ~120 °F | Broad coverage at ambient; fits caustics, sodium hypochlorite (≤ 12–19%), fertilizers, polymers, biodiesel, urea. | Water & wastewater, fertilizers, DEF, potable water, light-duty chemicals. |
| PP High Temp | Up to ~180 °F (200 °F in water) | Handles stronger acids/bases at heat; suitable for sulfuric (≤ 98%), HCl, nitric, phosphates, hot caustics. | Hot process water, high-temp chemical storage, reactors, food/bev with sanitizing cycles. |
| XLPE Compliance | ~140 °F continuous | Higher stress-crack resistance; engineered for aggressive chemistries where HDPE would fail (bleach, acids, oxidizers). | Heavy industrial duty, chemical distributors, water treatment, municipal compliance projects. |
Ratings available: 1.35 / 1.5 / 1.9 SG common; heavier by request. Opaque/UV-blocking builds available for sodium hypochlorite. Accessories: ladders, handrails, mixer mounts, immersion heaters, level indicators, side manways, secondary containment.
Specs that Pass Audits
James ties resin, SG rating, fittings, and restraints directly to chemistry, temperature, and site conditions — including wind/seismic — so tanks pass inspection and keep running for decades.
- Resin and wall logic sized to ASTM D1998.
- NSF/ANSI 61 potable options for water and process.
- Molded tie-downs + engineered restraint kits (wind/seismic).
- Siphon/maximum drain assemblies for safe, clean emptying.
