Epoxy Coated Steel Tank as a Food Grade Storage Tank: A hygienic and corrosion-resistant option for non-potable

Epoxy Coated Steel Tank as a Food Grade Storage Tank: A hygienic and corrosion-resistant option for non-potable

In the food and beverage, pharmaceutical, and agricultural industries, strict regulations govern the storage of liquids that are either used in production or involved in cleaning processes. While these liquids may be non-potable (not for drinking) or non-contact (not directly touching the final product), the storage vessels must still adhere to high standards of hygiene and structural integrity to prevent contamination of the entire facility and its products.

Traditional vessels can pose challenges: concrete is porous, and standard steel risks corrosion that can flake and contaminate process water or ingredients. This necessitates a highly reliable, corrosion-resistant storage solution.

Fusion Bonded Epoxy (FBE) Coated Steel Tanks are the optimal choice for Food Grade Storage Tank applications involving non-potable/non-contact liquids. By combining the strength of steel with a factory-fused, non-porous, and smooth epoxy surface, these tanks offer exceptional hygiene, long-term durability, and superior corrosion resistance. The Epoxy Coated Steel Tank provides a reliable, secure, and cost-effective foundation for supporting essential industrial processes.

The Essential Requirements of Food Grade Storage

Even when storing non-potable/non-contact liquids—such as wash water, process water, ingredient precursors, or industrial effluents—the storage tank must meet specific standards critical to industrial operations:

Hygiene and Cleanliness: The internal surface must be extremely smooth and non-porous to prevent the adhesion of biological films, sludge, and contaminants. This high standard of hygiene is essential for maintaining a clean facility environment and preventing cross-contamination risks.

Corrosion and Purity Control: The tank must offer guaranteed corrosion resistance to prevent rust particles from entering the liquid stream, which could compromise filters, pumps, or process quality. A durable, inert lining is non-negotiable for long-term durability.

Structural Reliability and Safety: These storage facilities often house large volumes of liquids that are critical to the manufacturing process. The vessel must be structurally robust to handle immense hydraulic loads, ensuring secure containment and operational safety over decades.

Compatibility with Washdown Chemicals: For tanks used in cleaning or process environments, the coating must withstand frequent exposure to detergents, sanitizers, and washdown chemicals without degradation, maintaining its corrosion-resistant barrier.

The FBE tank system is inherently engineered for these demanding industrial requirements, prioritizing both hygiene and long-term durability.

FBE Technology: Secure, Hygienic, and Durable Containment

The advantages of utilizing an Epoxy Coated Steel Tank as a Food Grade Storage Tank are rooted in the superior quality of the Fusion Bonded Epoxy process:

Hygienic, Non-Porous Surface: The factory-fused FBE coating results in an internal surface that is dense, smooth, and non-porous. This surface actively resists the adhesion of biological matter, ensuring a high level of hygiene and making routine cleaning faster and more effective.

Permanent Corrosion Resistance: The FBE polymer is chemically bonded to the steel under intense heat, creating a thick, uniform, and corrosion-resistant barrier. This protection is vital for food grade storage where any failure could lead to rust contamination, securing long-term durability and product purity.

Structural Strength and Modularity: Constructed from high-strength, precision-engineered steel, FBE tanks offer the structural integrity required for large-volume storage. The modular, bolted design allows for rapid, high-quality on-site assembly, minimizing disruption to ongoing food grade manufacturing or processing operations.

Secure and Liquid-Tight Containment: The modular panels are sealed using application-specific, durable sealants. This engineering ensures a secure, liquid-tight structure, which is essential for non-potable/non-contact liquids to prevent leaks that could compromise facility hygiene or environmental safety.

Economical and Long-Term Value: By providing a corrosion-resistant barrier that virtually eliminates the need for expensive internal re-linings or repairs, FBE tanks offer a high-performance long-term durability solution that is also cost-effective over its entire service life.

Project Case Studies: FBE Tanks Delivering Global Industrial Reliability

Our Fusion Bonded Epoxy tanks have a confirmed history of providing durable and reliable containment in environments demanding high standards of cleanliness and corrosion resistance for process liquids:

Cuba Rural Water Supply Project: We supplied a solution for a rural water supply project that demanded high integrity and a reliable water supply. This installation consisted of 2 tanks with a total capacity of 2,249 cubic meters, demonstrating the FBE solution's hygiene and long-term durability for essential, large-scale water storage.

Thailand Drinking Water Project: For a project requiring a high-quality, high-capacity solution for public use, we provided a tank that met demanding utility standards. This installation included 1 tank with a total capacity of 1,210 cubic meters, highlighting our capability to deliver a tailored, high-integrity solution suitable for clean process liquids and non-potable/non-contact liquids.

Landfill Leachate Treatment Project in Eastern China: Though storing highly corrosive fluid, this case demonstrates the exceptional scale and corrosion resistance of the FBE system. We provided 2 tanks with a total capacity of 10,392 cubic meters, confirming the FBE tank's structural and chemical superiority for containing vast volumes of liquid, a key requirement for large-scale industrial storage in food grade facilities.

Conclusion: Securing Industrial Processes with High-Grade Storage

The storage of non-potable/non-contact liquids within the food and specialized industries requires a vessel that offers uncompromising hygiene and structural long-term durability. Investing in a substandard solution risks both product integrity and facility safety.

The Epoxy Coated Steel Tank as a Food Grade Storage Tank is the strategic choice. Its factory-fused FBE coating provides a superior corrosion-resistant and non-porous surface. By choosing FBE technology, industries secure a robust, low-maintenance asset that safeguards the integrity of their process liquids and upholds the highest standards of industrial hygiene.
