HDPE Double Wall Vertical Tanks
A double wall tank is a tank inside a tank. If the inner tank ever leaks, the outer wall contains the chemical, giving you secondary containment without a separate dike or basin. HDPE handles a wide range of acids, caustics and water-based chemicals and is the most economical resin.
- 100 – 10,000 gallons
- HDPE resin
- Built-in secondary containment
Double wall tanks provide an extra layer of safety when dealing with hazardous chemicals.

The SG (specific gravity) rating is the heaviest liquid a tank is built to hold. Water is 1.0, so a 1.9 SG tank is made for liquids up to 1.9 times as heavy as water. Choose an SG rating at or above the specific gravity of your liquid. See our specific gravity chart.
Why this tank
Why Choose an HDPE Double Wall Vertical Tank
Tank-within-a-tank, built to standard
The inner and outer tanks are each rotationally molded in one piece, then welded, assembled and fitted at our Willis, Texas plant. Bailiff-molded HDPE vertical tanks of 500 gallons and larger meet or exceed ASTM D1998-21 wall thickness.
Economical, broad compatibility
HDPE suits many acids, caustics and water-based chemicals at the lowest cost per gallon. Check your chemical.
Built-in secondary containment
The outer wall contains any leak from the inner tank.
Outfitted to your spec
Flanges, couplings, tri-clamps, level indicators and tie-downs installed before the tank ships.

HDPE Double Wall Vertical Tank Questions
What sizes do HDPE double wall vertical tanks come in?
Our HDPE double wall vertical tanks range from 100 to 10,000 gallons. The table above lists stock sizes with dimensions, color and price. Need a size that isn’t listed? Ask us.
What does the SG rating mean?
The SG (specific gravity) rating is the heaviest liquid a tank is built to hold. Water is 1.0, so a 1.9 SG tank is made for liquids up to 1.9 times as heavy as water. Choose an SG rating at or above the specific gravity of your liquid. See our specific gravity chart.
Is HDPE compatible with my chemical?
HDPE suits many acids, caustics and water-based chemicals at the lowest cost per gallon. Check our chemical compatibility database or send us your SDS and we will confirm the right resin. Or compare resins in our tank resin guide.
Why choose a double wall tank?
If the inner tank ever leaks, the outer wall contains the chemical. That gives you secondary containment without building a separate dike or basin.
Do your HDPE tanks meet ASTM D1998?
Bailiff-molded HDPE vertical tanks of 500 gallons and larger meet or exceed the ASTM D1998-21 wall thickness requirements. Smaller tanks, and tanks we sell from other manufacturers, are not built to that standard.
Can you add fittings to the tank?
Yes. We install ANSI #150 flanges, threaded couplings and sanitary tri-clamps at our Willis, TX plant. Tell us the fitting types, sizes and locations when you request a quote.
Need a Different Size or Fitting Layout?
Tell us the liquid, volume and fittings. We’ll come back with a price and lead time.
