Poly Tanks
Poly tanks, or polyethylene tanks, are more durable and require less maintenance than comparable steel and fiberglass tanks. Poly tanks are used in the water treatment and chemical processing industries to hold such hazardous fluids as sodium hypochlorite, sulfuric acid, caustic soda, and hydrochloric acid.
Polyethylene (PE) is one of the many types of plastics from which storage tanks can be constructed. Polyethylene, a light, chemical-resistant thermoplastic, is the most commonly used plastic resin for storage tanks. The common types of polyethylene resins include linear high density (HDLPE), cross-linked high density (XLPE), and linear low density (LLDPE) resins.
Poly tanks have several advantages over the traditional steel tanks. Their seamless construction provides them with greater impact strength and superior resistance to rust, corrosion, chemicals, and fuel additives. These virtually indestructible tanks have a longer lifespan than steel tanks, which can fracture and leak. Poly tanks can easily be molded to fit tank compartments, unlike metal tanks, and are simple to install. Poly tanks also cost less overall than steel tanks.
