Typical Acid Strengths in Refining & Chemicals

HDPE, polypropylene and PVDF each handle sulfuric acid differently. See the compatibility chart for every rating.

75–93%

Concentrated acid

PVDF rated Excellent and HDPE rated Good. Polypropylene drops to Fair. Use PVDF fittings and Viton® gaskets.

93–98%

Commercial grade

Above the range of our compatibility database. Call us before storing 93–98% acid so we can review your application.

10–75%

Mid-strength acid

HDPE, polypropylene and PVDF all rated Excellent. Viton® gaskets Excellent; EPDM and Buna-N Good.

What to consider

Getting the Right Tank the First Time

Send the acid concentration, temperature, volume and fittings you need. We’ll match the resin, SG rating and gaskets.

  • Concentrated acid: refineries and chemical plants often handle acid above 93%. That is above the range of our compatibility database, so call us first.
  • PVDF for strength: PVDF is rated Excellent to 93%, where HDPE is rated Good and polypropylene Fair.
  • Containment and fumes: double wall tanks keep a leak and its fumes inside the outer tank.
  • Atmospheric storage only: our tanks are vented, not pressure vessels.
