Sodium Hydroxide Storage Tank Supplier and Manufacturer
At KDMSTEEL, you can get sodium hydroxide storage tanks in sizes ranging from 100 gallons to 20,000 gallons or custom for heavy industrial use.
We use tough materials like HDPE, XLPE, carbon steel, FRP, and even titanium to make sure that the tank does not melt or crack under the heavy weight of the chemical.
You can choose between a simple single-wall tank or a double-walled version to keep your floors clean and your workers safe.
We can build yours to stand vertically, lay horizontal, or give it a cone-shaped bottom for easy cleaning.
We can also add thick insulation and heat cables to keep the liquid sodium hydroxide from turning it into a block of ice.
Each of our sodium hydroxide storage tanks comes with EPDM gaskets and stainless steel bolts that will not rot away, and we can even hook up a full dosing system with pumps and pipes if you require it.

Choosing the Right Material: Top 5 Most Common Types KDMSTEEL Use
At KDMSTEEL, we will help you choose the right material for your sodium hydroxide tank based on your specific application, depending on your budget and how long you want the tank to last.
-
Polyethylene Tanks (HDPE and XLPE)These are good for standard storage and offer better structural integrity and resistance to the “stress cracking” that caustic soda can cause.
-
Polypropylene TanksThese tanks can handle temperatures from 68°F all the way up to 212°F and they are more resistant to the corrosive “bite” of caustic soda than HDPE, though they usually come with a higher price tag.
-
Carbon Steel TanksThese can be tough and can handle NaOH concentrations but we recommend a heat treatment process for this tank to make them more durable, you can also line them with natural rubber to prevent “iron pickup” and rusty mess.
-
Titanium TanksIt has a 30+ years of service life and is used in high-throughput facilities where you cannot afford even a single hour of downtime for repairs. It is expensive but worth every penny.
Why KDMSTEEL Sodium Hydroxide Storage Tanks Stand Out
KDMSTEEL expertise in building systems that solve the everyday problems of running a business and here is a quick look at why our sodium hydroxide storage tanks are a smart investment for your facility:

We build our tanks with a 1.9 Specific Gravity rating and use Hexene PE, this means that the walls are thicker and the plastic is stronger so your tank will not sag, crack, or thin out over years of heavy use.

KDMSTEEL offers conical bottoms that allow the liquid to drain out completely and our plastic tanks are also rotationally molded, the interior is smooth with no seams or sharp corners for chemicals to hide in.

Our tanks come with built-in UV stabilizers that act like a permanent sunscreen when they are installed outdoors, this prevents the material from getting brittle or “chalky” aven after years of direct sunlight.

At KDMSTEEL, we can add clear sight gauges or ultrasonic level sensors so you can check your inventory easily and avoid running out of stock.
KDMSTEEL Double-Walled Tanks: Your Built-In Safety Net
At KDMSTEEL, we often recommend double-wall HDPE or XLPE sodium hydroxide storage tanks, so if the inner tank leaks, the outer tank catches the spill. You do not lose your product, you do not damage the floor, and you do not put your employees at risk. Plus, you can often keep using the tank until repair is scheduled, rather than having an immediate emergency.


The KDMSTEEL Difference: Hexene PE Technology
KDMSTEEL also offers sodium hydroxide storage tanks that are built with 1.5SG and 2SG Hexene Polyethylene (PE). Whether you are storing light concentration or heavy 50% caustic, our hexene-based tanks are designed to handle the weight and the chemical “burn” without thinning out over time.
KDMSTEEL Dosing Systems: The Tailored Solution
If your engineers have a specific P&ID (Piping and Instrumental Diagram) or you need to meet water utility standards, we build dosing systems for your sodium hydroxide storage tanks. We can connect these directly into your existing setup, ensuring that the pumps, sensors, and tank work in perfect harmony.


KDMSTEEL Engineering Standards: API-650 and Wall Thickness
We fabricate steel sodium hydroxide storage tanks to the API-650 standard and because sodium hydroxide is aggressive, we increase the calculated thickness of our tanks to ⅛ “ to ¼ “ as a “corrosion allowance”.

At KDMSTEEL, we wrap our sodium hydroxide storage tanks in thick foam insulation and add electric heating cables to keep the liquid warm.
Yes, we offer pre-built systems that come with all the pumps and valves already mounted and ready to go.
Because when you fill a tank quickly, air needs a way to get out fast so your tank does not swell or pop. KDMSTEEL install vents that are four times bigger than your fill pipe to keep the air pressure safe.
KDMSTEEL has a wide selection of colors you can choose from, but we usually suggest a “natural” white finish for plastic tanks to see the liquid level easily from looking outside the tank.
For almost every caustic soda setup, EPDM is the best and most affordable choice.
You should check the bolts and gaskets once a year to make sure that they are still tight and dry.
If you take care of it, our plastic tanks usually last between 10 and 20 years in a busy workplace and our steel and titanium tanks can last more than 30 years.
Many of our standard plastic tanks are in stock and can be shipped out in just a few weeks. Custom tanks will take a bit longer because we test them thoroughly before they leave, we will always give clear updates.
