Storage Tank Protective Coatings

Approximately 2500 different types of  liquids are stored in storage tanks around the world. 52 liquids make up 80% of the liquids in storage. Most commonly these are water, oils, chemicals, solvents, alcoholic beverages and fuels. The coating selection is critical to ensure the correct coating is applied for the material that is being stored. A leak or failure due to corrosion can have a catastrophic result. There is a chance of fatalities and environmental damage plus the huge cost of the downtime and lost productivity.

A study calculated the cost of downtime for two separate storage tanks

Example 1:
Shell – Coating & corrosion problems in Crude Oil Tank:  – 48 m diameter
Coating failure with severe pitting of floor plates
Downtime Cost: US$ 67,000/day

Example 2:
BP – Crude Oil Tank: – 78 m diameter
Coating failure with pitting of the floor plates
Downtime Cost: US$ 58,000/day

Can you afford a failure in your storage tank?

 

 

Tank Lining Coating Selection Criteria

Chemco have a total range of tank lining systems for your requirements. Your system will be designed to suit your tank type and surface condition. We will consider your expected lifetime to first maintenance. Other things to consider are, what is the product being stored. What is the temperature to be stored at. What is the duration of the storage. If the product to be stored is highly aggressive chemical, we will be specify a system to suit the pH level. If the product is an alcoholic beverage we have a coating specially formulated to protect this liquid asset for you.
