Glass-Fused-to-Steel Bolted Tanks for Aquaculture Fish-Rearing

Benefiting from the mechanical strength of steel plates and the strong acid-alkali resistance of the inorganic enamel glaze layer, glass-fused-to-steel bolted tanks feature smooth inner walls less prone to sediment adhesion, detachable structure for capacity expansion and fast-track construction. Therefore, they are widely applied in biogas-related environmental-protection projects, water-treatment works, industry-agriculture sectors, food and pharmaceutical processing, chemical storage and transportation, municipal water supply, energy storage, aquaculture and many other fields.

•Most importantly, the chemically‑inert enamel glaze layer will not contaminate aquaculture water.

•The inner surface of enamel‑coated steel panels is extremely smooth and resists the adhesion of algae, fish excrement and biological fouling.

•The tanks are compatible with highly‑corrosive breeding water such as seawater and saline‑alkali water.

•Factory‑prefabricated bolt‑on assembly enables rapid construction, flexible specifications, as‑well‑as later‑stage capacity expansion and relocation.

•Complete recirculating aquaculture systems can be conveniently constructed with these tanks.

•Conventional concrete ponds tend to leach alkaline substances and trigger sharp pH fluctuations of water.

•The rough interior wall of concrete tanks is susceptible to algae growth and dirt buildup, bringing heavy‑duty cleaning work.

•Once constructed, the volume of concrete ponds is fixed and cannot be adjusted.

• Base material: special titanium‑rich high‑strength enamel‑qualified steel plate Low‑carbon titanium‑specialized steel is adopted. The steel boasts excellent yield strength, tensile strength and elongation property. It features good impact‑resistance and deformation‑resistance, capable of withstanding stress generated by water pressure, material load and temperature fluctuation, so steel‑plate cracking seldom occurs.

• Molecular‑bonded inorganic glass‑enamel layer formed through high‑temperature fusion Enamel glaze is applied to both sides of steel plates and then fired at 820‑930 °C. Molecular‑level combination is achieved between the glass enamel and steel substrate, which prevents the glaze layer from simple coating peeling‑off.

• High chemical inertness of glaze layer and multi‑form corrosion resistance The inorganic glass substance keeps stable chemical property. It resists liquid‑phase and gas‑phase corrosion from organic acid, hydrogen sulfide, acid‑alkaline medium and salt‑containing wastewater. It adapts to harsh working‑conditions including anaerobic digesters, livestock‑manure storage tanks and industrial wastewater tanks.

• Modular‑designed steel panels with consistent material performance All enamel‑coated steel panels go through standardized glaze spraying, high‑temperature sintering and quality inspection inside the factory. The enamel thickness and physical‑chemical parameters of every panel are under precise control for stable finished‑product quality.
