Choosing the Correct Plastic Material for Tanks

When designing tanks for chemical and fluid handling services, engineers have a variety of material options. Choosing the correct material from metals, plastics, coatings, and combinations thereof can majorly affect the lifetime of the tank. Plastic tanks can be specified over metals due to their corrosion resistance, lightweight properties, and ease of fabrication. This article examines some plastics most commonly used for tank constructions, both as liners inside metal or fiberglass tanks, as well as freestanding ones.
