Fire Water Storage Tank for Securing Water Safety
description
Firefighting water storage is a special system that remains stationary most of the time, but must be put into immediate use in an emergency. In this situation, attention must be paid to issues such as microbial growth, sediment accumulation, and increased water corrosivity. Due to the material properties of GFS tanks and epoxy coated steel tanks, they can ensure that long-term contact with fire-fighting water without causing corrosion, water pollution, or less of strength.
The Glass fused to steel (GFS) tank is a kind of bolted storage tank made from two materials: glass and steel. High-strength TRS (titanium-rich steel) plates and enamels are perfectly fused at high temperatures to form a highly inert inorganic glaze layer. This coating system has excellent anti-corrosion properties.
Material Characteristics of Glass-Fused-to-Steel Tanks
-Low Carbon, High Strength, High Titanium.
The steel substrate employed in the construction of glass-fused-to-steel tanks is a special high strength enamelled steel with a unique design and superior properties. Its mechanical properties, including yield strength, tensile strength, and elongation, far exceed those of conventional steel sheets.

(enamel plate)
The epoxy coated steel bolted tanks (FBE tanks) are made of steel panel which coated with the fusion bonded epoxy internally and externally. High-strength bolts were used for on-site connection and sealing assembly, so that it can achieve efficient corrosion protection and rapid construction, and is widely used in the field of environmental water treatment.

Features Of Epoxy Coated Steel Tanks
• Excellent corrosion resistance
Wide chemical resistance: It can withstand corrosion from various acids, alkalis, salts, organic solvents, and some oxidants, making it suitable for storing corrosive media in industries such as chemical, electroplating, and pharmaceutical.
Long-term stability: It is not easily aged or degraded in complex chemical environments, resulting in a long service life.
• High mechanical strength and wear resistance
Robust structure: The epoxy resin material has high hardness, good impact and compressive strength, and can withstand certain external loads.
Wear and scratch resistant: The smooth and wear-resistant inner wall is suitable for storing suspensions containing solid particles.Aesthetics: The smooth, uniform surface of FBE steel tanks improves the appearance of the tank and surrounding area.
• Lightweight and high-strength, easy to install
Lightweight: Weighs significantly less than steel or concrete tanks of the same volume, reducing transportation and installation costs.
Modular design: Partially assembleable on-site, adaptable to large or special site requirements.
• Excellent insulation properties
Electrical insulation: Non-conductive, suitable for special storage applications in the electronics and power industries (such as insulating oil and electrolytes).
Anti-static design: Anti-static function can be achieved by adding conductive materials, suitable for flammable and explosive environments.
• Flexible customization and adaptability
Flexible shape and size: Vertical, horizontal, and irregularly shaped structures can be customized to suit different spaces.
Reinforced lining: Can be composited with fiberglass (FRP) or modified resin to further improve temperature and pressure resistance.
• Low maintenance costs
No coating required for corrosion protection: Unlike metal tanks, no regular application of anti-corrosion coatings is needed.
Easy cleaning: The smooth inner wall prevents material buildup, making cleaning simple and reducing residue.
• Environmental Protection and Safety
Non-toxic and Pollution-Free: Food-grade epoxy resin can be used for the storage of drinking water and food additives.
Flame Retardant Option: Flame retardant properties can be achieved through formulation adjustments to meet fire safety requirements.

In short, if the layout is sufficient, transportation conditions are good, and maximum corrosion protection is desired, GFS tanks (enamel tanks) can be chosen; however, given current trends and technological maturity, epoxy resin tanks are a more suitable choice for high-tonnage fire-fighting water storage tanks.
