Choosing the Proper Lines and Tanks for Concentrated Acid

Ensuring any concentrated acid is correctly contained is vital to avoid disaster. Acids that are highly corrosive start to challenge traditional options for storing. Many of these need specialized containers to be safely contained.

Corrosion is the gradual degradation of materials. It is one of the most important factors to consider when containing acids. This guide will help you to choose the most correct lines and tanks for different acids.


Choosing the Correct Lines and Tanks for Concentrated Acid

The best way to contain concentrated acid is to place it inside a treated structure. These structures are usually coated with a corrosion-resistant, high-performance coating. They offer good resistance against abrasion and corrosion. 


Sulfuric Acid

Sulfuric acid is a high-density, corrosive acid that is also known as dihydrogen sulfate and battery acid. This acid is used in many different industries. It is also a highly reactive acid and can cause hazardous situations when not stored correctly.

Three tanks are suitable to hold sulfuric acid. The first is carbon steel sulfuric tanks, they are a popular choice when storing large quantities of 93wt%. You must perform regular tank maintenance and inspections.

The second is polyethylene HDPE sulfuric acid tanks. These are used for smaller amounts of sulfuric acid. The thermoplastics are not as reactive as carbon steel can sometimes be.

The last is fiberglass reinforced plastic tanks. These are recommended for sulfuric acid with a concentration of 80wt% or lower. This type of tank must remain cool to avoid violent reactions.


Hydrochloric Acid

This acid has many uses in many different areas. It also has many different hazards to containers and handlers. Hydrochloric acid has two main storage containers.

The first is a fiberglass reinforced plastic tank, which is made up of layers mixed with resin. You should equip these storage tanks with decent ventilation. If not some tanks might not stand the vacuum or pressure.

The second is rubber-lined steel tanks, these use welded steel. This type of tank is slightly more expensive. It can hold larger quantities than the FRP tanks.


Nitric Acid

Nitric acid is highly corrosive and destroys a variety of materials quickly. Nitric acid is mostly contained in cross-linked polyethylene tanks for large amounts. For smaller quantities, using linear polyethylene tanks is best.

If your nitric acid has 30-49% concentration, they recommend the XLPE tanks. These concentrations should also be under 100°F.

Characteristics to look for in a good lining include sealed gaps, impermeable barriers and it adheres to the substrate fully.
