HDPE Chemical Storage Tanks
Material-Mastered, Not Catalog-Guessed
High-Density Linear Polyethylene (HDLPE) tanks engineered by James Riggins for about 95% of industrial and municipal chemicals. From extrusion-wound rectangular tanks that never bulge to double-wall sulfuric acid systems and vented tanks, every spec is tuned to the chemistry, temperature, and duty cycle.

Most HDPE tank failures are not “material problems” — they are spec problems. Wall too thin. SG too low. Wrong resin for the temperature. No venting. Rigid pipe glued to a flexing wall. The Riggins Multiplier is James' 30+ years of field experience applied to every decision.
- HDLPE up to ~120°F
- Polypropylene (180–200°F) or FRP When HDPE Limits Are Exceeded
- NSF/ANSI 61 · FDA · EPA/SPCC · Seismic/Wind Restraints
- Double-Wall SAFE-Tank® Systems Available
Frequently Asked Questions
What percentage of industrial chemicals is HDPE compatible with?
HDPE (specifically HDLPE) covers roughly 95% of industrial and municipal chemicals when correctly specified for resin, wall thickness, and temperature.
What is the temperature limit for HDPE tanks?
The recommended HDPE temperature limit is around 120°F — beyond that, polypropylene (180–200°F) or FRP should be considered instead.
Why do HDPE tanks fail even when the material seems compatible?
Most HDPE tank failures are spec problems, not material problems — wall too thin, SG too low, wrong resin for the temperature, no venting, or rigid pipe glued to a flexing wall.
