Vertical Sulfuric Acid Storage Tanks
Our vertical sulfuric acid storage tanks are available in commercial and industrial design standards.
Our sulfuric acid tanks are available in HDLPE - High-density linear polyethylene and XLPE - High-density cross linked polyethylene.
Sulfuric acid resin available for tanks up to 15,000 gallons.
Our Sulfuric Acid storage tanks are made for Sulfuric Acid concentrations up to 99%
Tanks rated with at least 1.9 specific gravity recommended.
Welded-in Polyethylene flanges or couplings, or CPVC threaded fittings with viton gaskets recommended.
Sulfuric Acid Storage Challenges
Due to the weight of Sulfuric Acid it will push the limits of mechanical integrity of any plastic or polyethylene tank.
Adding water to sulfuric acid that is concentrated can lead to sulfuric acid aerosol dispersal and in the worst case scenario - an explosion.
The accidental spillage of sulfuric acid on metals can produce highly flammable hydrogen gas.
Sulfuric acid burns are severe - sulfuric acid dehydrates whatever it comes into contact with and the heat produced from the reaction can cause second degree burns.
Sulfuric acid should not be stored with organic materials or within specific metal containers to prevent fire, explosion or the generation of toxic fumes and flammable gases.
Important Sulfuric Acid Storage Tank Considerations
HDPE or XLPE should be used for the entire tank to attain a higher tensile strength and improved sulfuric acid chemical resistance.
High Density linear resin is considered the best poly chemical barrier, with the most chemical resistance and in turn prolongs tank life and is repairable by welding if the tank is damaged.
Sulfuric Acid containers should be kept in a cool, dry and well ventilated area. Containers should be tightly sealed to prevent exposure to foreign materials and temperature changes.

Ferric Chloride Tank Venting
Ferric Chloride Tanks are designed for use at atmospheric pressure. Pressure or a vacuum may cause the tank to deform or for damage to occur to the tank and void the tank’s warranty.
Venting equipment must be sized to limit the pressure or vacuum in the tank to a maximum of 1/2” water column which corresponds to 0.018 PSI. Pneumatically filled tanks may require additional pressure relief.
Ferric Chloride Tank Foundation & Restraints
Ferric Chloride Tanks should be positioned on a smooth concrete or asphalt pad to provide the tank with adequate support. Make sure the pad is clean, smooth and level so there is no deflection in the bottom support of the Ferric Chloride Tank.
If seismic restraint must be employed use a pad that is large enough for anchor plate attachments per the requirements in the seismic code.

Tanks are designed for use at atmospheric pressure. Pressure or vacuum situation can cause excessive deformation or damage to the tanks and void warranty. Venting equipment should be sized to limit pressure or vacuum in the tank to a maximum of ½” water column (0.018 PSI). If the tank will be pneumatically filled (through tanker discharge) additional pressure relief may be required.
Sodium Hypochlorite Tank Foundations & Restraints
Tanks should be positioned on a smooth concrete or asphalt pad providing adequate support. The pad should be clean, smooth and level so it fully supports the entire tank bottom with no deflection. If a seismic restraint system is used the pad must be adequate in size for anchor plate attachments per the seismic code.
Sodium Hypochlorite Tank Temperature
Product should not exceed 100 degrees F at delivery or during storage to reduce decomposition of the Sodium Hypochlorite
Caution - The life of a tank is affected by the quality of the sodium hypochlorite stored. Tank owners are cautioned to use high quality sodium hypochlorite with low iron, nickel, and copper content. These metals contribute to the decomposition of the sodium hypochlorite and accelerate the oxidation and degradation of the tank.

Sodium Hydroxide Tank Plumbing
Sodium Hydroxide tanks require flexible connections with fittings.
You need to allow for %4 lateral and vertical contraction / expansion of the Sodium Hydroxide Tank.
The flexible connections, additional piping and valves must be supported independently of the tank sidewall and dome.
Sodium Hydroxide Tank Venting
Our Sodium Hydroxide Tanks are designed for use at atmospheric pressure. Pressuring or a vacuum can damage the tank and cause deformation. Venting equipment needs to be sized appropriately to limit pressure or the creation of a vacuum in the tank to a maximum amount of 1/2” water column.
Pneumatically filled tanks may require additional pressure relief.
Sodium Hydroxide Tank Foundations & Restraints
Tanks should be positioned on a smooth surface such as a concrete or asphalt pad that can provide adequate support for the tank. Make sure the pad is clean, smooth and level so there is no deflection in the bottom support of the tank. Seismic restraints should be attached using seismic anchor plate attachments per your local seismic code.
Sodium Hydroxide Tank Temperature
Product should not be stored or exposed to temperatures in excess of 100 degrees Fahrenheit.
Calcium Fertilizer Storage
Calcium - Ca is often blended with other chemicals / nutrients to act as a liquid fertilizer. Our tanks are perfect for Calcium storage when blending your own liquid fertilizer. Calcium promotes promotes plant growth and can help younger plants establish their roots.
Calcium Fertilizer decreases the chance of blossom-end rot on tomatoes, increases tomato growth and vigor.
Magnesium Fertilizer Storage
Poly and plastic tanks are a great choice for Magnesium - Mg liquid fertilizer storage and blending. We offer tanks in HDPE and XLPE models for superior storage abilities.
Magnesium fertilizer regulates plant food absorption and aids in formation of seeding.
A variety of plants see direct benefits from Magnesium liquid fertilizer including blueberries and azaleas. These type of plants grow in acidic soil so blending your own liquid fertilizer consisting of sulfur, magnesium and iron will encourage ideal size and color.
Nitrogen Liquid Fertilizer Storage
Nitrogen - N is an essential plant nutrient which promotes full plant development. For example your lawn requires a high level of nitrogen because the grass is constantly growing. Our HDLPE and XLPE tanks are great storage containers for Nitrogen that is going to be mixed to produce your own liquid fertilizer.
Phosphorus Plant Fertilizer Tanks
Phosphorus helps strengthen roots and increases the average bloom size of your plants. Phosphorus is commonly used as a fertilizer for flowers to encourage bigger blooms when the flower is in season.
Potassium - K Fertilizer Storage
Potassium is one of the more aggressive promoters of growth and helps strengthen a plant’s immune system. Potassium is commonly used as a liquid fertilizer in agricultural applications to promote fruit growth.
Fertilizer Tank Guidelines
Above Ground Liquid Fertilizer Tanks TFI Guidelines for Mechanical Integrity
Sulfur Tanks
Sulfur - S also gives plants a more vivid green color and can be used alone or in combination with Potassium to promote vigor plant growth.
Blending your own liquid fertilizer can be complicated but it is important that you have the proper capacity tank to mix your chemicals. Plastic and Poly tanks are a great storage container for Liquid Fertilizers.

Tanks are designed for use at atmospheric pressure. Pressure or vacuum situation can cause excessive deformation or damage to the tanks and void warranty. Venting equipment should be sized to limit pressure or vacuum in the tank to a maximum of ½” water column (0.018 PSI). If the tank will be pneumatically filled (through tanker discharge) additional pressure relief may be required.
Hydrochloric acid in concentrations above 10-20% is a volatile liquid and will start fuming at ambient temperatures. These fumes can be corrosive to the environment around the tank. For this reason a bolted and sealed (fume tight) manway should be considered for hydrochloric acid tanks and special considerations should be taken for venting the tank to a scrubber system.
Hydrochloric Acid Tank Foundation and Restraints
Tanks should be positioned on a smooth concrete or asphalt pad providing adequate support. The pad should be clean, smooth and level so it fully supports the entire tank bottom with no deflection. If a seismic restraint system is used the pad must be adequate in size for anchor plate attachments per the seismic code.
