Glass-Fiber-Reinforced-Plastic (GRP) Tank

Glass-Fiber-Reinforced-Plastic (GRP) Tank – Lightweight, Corrosion-Proof Storage

Manufactured by filament-winding or hand-lay-up, GRP tanks combine glass-fiber reinforcement with thermoset resin to yield a lightweight, high-strength vessel immune to rust, acids and salts. Standard vertical designs range 1–150 m³, with diameters up to 4 m and heights to 12 m; horizontal models suit confined footprints. Wall construction offers UV-stable gel-coat, chemical-resistant vinyl-ester inner liner, and optional resin-rich veil for food-grade service. Operating limits are −40 °C to +120 °C and atmospheric to 3 bar internal pressure. Integral properties eliminate cathodic protection, reduce transport weight 70 % versus steel, and cut installation cost 30 %. Typical uses include HCl, NaOH, brine, demineralised water, ferric chloride and sodium hypochlorite in Water Treatment, plating plants and paper mills. Accessories—manholes, flanges, level gauges, ladder platforms—are factory-moulded, ensuring leak-free joints. With 50-year design life, minimal maintenance and fast site assembly, GRP tanks provide economical, long-term storage for aggressive chemicals and high-purity liquids alike.
