Agricultural Bolted Water Storage Tanks Low Maintenance Corrosion Resistance

A bolted steel storage tank is a specialized type of storage tank where steel panels are coated with a layer of glass, commonly referred to as vitreous enamel. This innovative combination of materials provides exceptional durability, corrosion resistance, and an extended service life, making it an ideal solution for a wide range of industrial applications.

The construction begins with high-quality steel panels that are pre-fabricated in a controlled factory environment. These panels undergo rigorous quality control to ensure they meet stringent standards for thickness, strength, and dimensional accuracy. Once ready, they are transported to the installation site and assembled using bolts and gaskets to form a robust, watertight structure.

The key feature is the vitreous enamel coating applied to both interior and exterior surfaces through a multi-step process involving cleaning, priming, and high-temperature firing. This creates a seamless, impermeable barrier with coating thickness typically ranging from 250 to 450 micrometers (μm), providing superior protection against corrosive elements.

The enamel layer protects the steel from rust and corrosion while enhancing resistance to mechanical damage. These tanks perform exceptionally well in harsh environments exposed to extreme weather, chemicals, or abrasive substances.

In wastewater treatment facilities, they withstand aggressive acidic and alkaline solutions. In the oil and gas industry, they reliably store corrosive chemicals like sulfuric acid and saltwater while maintaining structural integrity.

The vitreous enamel coating offers unparalleled corrosion resistance, forming a permanent bond with the steel that prevents interaction between stored materials and the tank surface. Unlike traditional coatings that may peel or flake, this enamel maintains integrity over time.

The smooth enamel surface minimizes residue buildup, simplifying maintenance while providing reliable containment for hazardous substances in industries like petrochemicals.

With durable materials and advanced manufacturing, these tanks offer decades of service with minimal maintenance. The modular design allows for easy expansion or relocation, providing flexibility for growing operations.

These tanks serve diverse industries including:

• Water/wastewater management (potable water, sewage, treated effluent)
• Food and beverage (ingredients, finished products, by-products)
• Chemical industry (acids, bases, solvents, reactive compounds)
• Pharmaceuticals (sensitive compounds and formulations)

The non-toxic enamel ensures material purity while the long service life reduces replacement frequency, minimizing waste and resource consumption.

The steel substrate is specialized high-strength enamel steel with enhanced mechanical properties:

• Yield Strength: Higher than standard steel, resisting deformation under pressure
• Tensile Strength: Superior resistance to pulling/stretching stresses
• Elongation: Absorbs energy before fracturing, enhancing durability

• Low Carbon Content: Excellent weldability and formability
• High Strength: Allows thinner walls without compromising integrity
• High Titanium Content: Improves corrosion resistance and durability

These advanced properties make GFS bolted tanks ideal for demanding environments in water/wastewater, petrochemicals, food processing, and chemical storage where durability and reliability are essential.
