Custom Plastic Tanks

Miller Plastics' custom plastic tanks range in size from less than 1 cubic foot to more than 50 feet long.
Corrosive or harsh chemical environments require tanks with unique features.
We design and construct plastic tanks to meet the most demanding specifications.
Many of our custom-fabricated plastic tanks are annealed for maximum strength.
At Miller Plastics, we have 40+ years of experience creating single tanks, as well as integrated systems that include process piping or ancillary features for a specific manufacturing process.
All of our plastic tanks are fabricated with 100% virgin American-made materials.
Self-supporting tanks can be reinforced with plastic-encapsulated steel bands or internal baffles to minimize sidewall bowing. Welds are smooth and burr-free to minimize sediment buildup and allow for easy cleaning.
We manufacture plastic tanks in a wide range of shapes, sizes and dimensions in corrosion-resistant materials for a variety of uses in harsh environments.
Plastic Tank Materials
Polypropylene - superior working temperature and tensile strength
Lexan® - outstanding mechanical, optical, electrical and thermal properties
PVC - Polyvinyl chloride known for its inexpensive nature and flexibility
Polyethylene - Low Density (LDPE), High Density (HDPE) and Ultra High Molecular Weight (UHMW PE)
CPVC - low cost, high glass transition temperature, high heat distortion temperature, chemical inertness, and flame and smoke properties.
Kynar® - for applications requiring the highest purity, strength, and resistance to solvents, acids, bases and heat
