A Double Wall HDPE (High Density Polyethylene) Storage Tank can be an excellent choice if you need secondary containment with a limited footprint. Double Wall tanks are closed containment systems that keep rain, dirt, leaves and debris from getting into the secondary containment tank.
Bailiff Enterprises makes double wall HDPE storage tanks up to 10,000 gallons in size. Both the primary and secondary tanks are each molded as one seamless piece without stress on the plastic that can come from fabricating tanks. The primary tank and the secondary containment tank are joined by thermoplastic welding them together.
HDPE (High Density Polyethylene) is the most widely plastic for storage tanks due to its low cost, corrosion
resistance and good chemical compatibility. HDPE is sometimes conveniently but incorrectly referred to as HDLPE. For storage applications that require temperatures up to 200 F., we offer polypropylene storage tanks. For applications that require temperatures up to 300 F., we offer Kynar (PVDF) storage tanks.
The polyethylene tanks we mold meet standards set by ASTM D 1998-21.
