Key Specifications

Physical Dimensions

• Size: 16″ diameter × 65″ height (~406 mm × 1651 mm) — often referred to as 16×65.

• Capacity: Around 185–200 litres depending on media load and liner thickness.

• Colour: Typically blue.

Design and Construction

• Material: Fiberglass Reinforced Plastic (FRP) body with a seamless Polyethylene (PE) inner liner.

• Manufacturing: Made using advanced filament winding technology — high strength, lightweight, and corrosion-resistant.

• Opening: Usually 4″ top and bottom threaded connections for valve installation and media access.

Operating Parameters

• Maximum Operating Pressure: ~150 psi (≈10 bar) — supports typical industrial and residential system pressures.

• Max Operating Temperature: ~65 °C (varies by model) — can handle hot water pre-treatment conditions.

• Maximum Vacuum: ~127 mmHg (5″ Hg).

• Safety Factor: Designed with a safety factor (e.g., 4:1).

• Burst Strength: Typically high (e.g., ~40 bar) due to filament winding control.

Durability & Warranty

• Corrosion Resistance: Excellent, FRP resists rust and chemical attack.

• Maintenance: Low upkeep compared with metal tanks.

• Warranty: Often around 1 year against manufacturing defects.

Typical Applications

The Tata Steel 1665 FRP Vessel is widely used in many water treatment scenarios:
✔ Domestic and commercial water softeners
✔ RO (Reverse Osmosis) pre-treatment filtration
✔ Sand and activated carbon filter housings
✔ Industrial water purification systems
✔ Municipal and government water treatment projects

In these systems, the vessel functions as a container for filter media (like sand, activated carbon, resin) through which water flows under pressure to remove turbidity, particles, hardness, and other contaminants. RoeStore
