Engineered for the harshest industrial environments, our Heavy-Duty FRP (Fiberglass Reinforced Plastic) Chemical Storage Tanks provide a superior solution for the containment of aggressive acids, alkalis, and solvents. Unlike traditional metal tanks that require frequent maintenance or rubber linings, our filament-wound fiberglass tanks offer a monolithic, leak-proof structure with inherent corrosion resistance throughout the vessel wall.
Designed to replace stainless steel and lined-steel vessels, this corrosion-resistant acid & alkali vessel is ideal for storage of sulfuric acid, hydrochloric acid, sodium hydroxide, and wastewater, ensuring long-term safety and compliance with environmental regulations.
Advanced Filament Winding Technology: Manufactured using computer-controlled micro-winding processes, ensuring a high glass-to-resin ratio for maximum structural strength and hoop tensile stress resistance.
Superior Chemical Resistance: The inner liner is fabricated using premium Vinyl Ester or Epoxy resins (such as Derakane 411/470 equivalent), specifically selected based on your chemical medium to prevent corrosion, blistering, or delamination.
Standards Compliance: Fully designed and manufactured in accordance with ASTM D3299 (Filament-Wound Glass-Fiber-Reinforced Thermoset Resin Corrosion-Resistant Tanks) and ASME RTP-1 standards.
Maintenance-Free Durability: The exterior features a UV-resistant, resin-rich topcoat that withstands weathering, requiring no painting or rust-proofing, with a design life exceeding 20 years.
Customizable Configurations: Available in Vertical Flat Bottom, Vertical Cone Bottom, Horizontal, and Double-Wall designs to suit specific site requirements.
We provide rigorous engineering based on Finite Element Analysis (FEA) to ensure safety under specific loads (wind, seismic, internal pressure).
