Chemical & Industrial Tanks

Plastic tanks for acids, alkalis and industrial liquids

Our chemical tanks hold acids, alkalis, process chemicals and other corrosive liquids in polyethylene or polypropylene (PP), from 1 to 20,000 gallons. Styles include vertical bulk, cone bottom, open top, rectangular, tapered and double wall tanks, from Chem-Tainer, Peabody Engineering, Ronco, Custom Roto-Molding, Norwesco and Enduraplas. Not sure which tank suits your chemical? Start with our Chemical Storage Solutions guide.

Check two things first: that the tank material suits your chemical, and that the tank's specific gravity rating (for example 1.5 or 1.9) is at or above the specific gravity of the liquid you store. Where a leak must be held, choose a double wall tank or add secondary containment.

Guides for Chemical & Industrial Tanks

Choosing a chemical tank

Tank styles

  • Vertical bulk tanks hold bulk chemicals on a level pad. See vertical chemical storage tanks.
  • Cone bottom tanks drain completely through a center outlet for mixing and batching, and sit on a stand. See cone bottom tanks.
  • Open top tanks, cylindrical, tapered or rectangular, are for dipping, mixing and filling from above, in sizes down to 1 gallon. Closed top and solid top process tanks keep the liquid covered. See open top tanks.
  • Double wall and dual containment tanks add a second wall that holds a leak from the inner tank. See double wall tanks.

Specialty tanks

  • Chem-Tainer acid neutralization tanks for acid handling.
  • Chem-Tainer pharmaceutical processing tanks and brine tanks.
  • Peabody Gemini waste oil and antifreeze tanks for used oil and fluid collection.
  • Norwesco inductor cone bottom tanks and chemical injection tanks.

Protecting against leaks

Double wall tanks and secondary containment systems guard against leaks and spills, and spill containment covers drums and totes stored nearby. Our guide on chemical tank compatibility and SPCC covers matching the tank to the chemical and the containment rules that apply.

Fit-out and uses

Polyethylene tanks resist corrosion, weigh little and are easy to place and maintain. Many models take lids, fittings and stands so the tank fits your process, and the chemical storage guide explains why those parts must suit the chemical too. They serve manufacturing, agriculture, pharmaceutical and commercial sites, for bulk chemical storage, acid handling and oil containment.
