Description
Nikunj Fibre Glass is a premier manufacturer and supplier of heavy-duty FRP Duct Pipes & Chemical Fume Exhaust Ducting Systems based in Vapi, Gujarat. Engineered with premium vinyl ester and isophthalic resin formulations, our fiberglass ducting solutions provide complete corrosion resistance against aggressive acid mists, hot chemical gases, and wet industrial vapors.
Key Features & Engineering Advantages
- Superior Chemical & Acid Resistance: Built with a 2.5mm–3.0mm resin-rich inner corrosion barrier with C-glass surface veil to withstand hydrochloric acid (HCl), sulfuric acid (H2SO4), nitric acid, wet chlorine gas, and industrial solvent vapors.
- High Structural Strength & Lightweight: Filament wound or contact molded with alternating layers of chopped strand mat (CSM) and woven roving (WR), delivering superior rigidity with one-quarter the weight of steel ducting.
- High Temperature Tolerance: Continuous operation up to 120°C using vinyl ester resin systems without softening, sagging, or thermal deformation.
- UV & Weatherproof Exterior: Formulated with UV inhibitors and paraffin wax topcoat for outdoor rooftop installations in harsh coastal and industrial environments.
- Seamless Low Friction Interior: Mirror-smooth interior bore minimizes static pressure loss, reduces fan power consumption, and prevents particulate sludge buildup.
Components & Duct Fittings Range
- Round & Rectangular FRP Ducts: Standard round ducting from 150 mm to 1500 mm diameter and custom fabricated rectangular duct profiles.
- FRP Segmented & Moulded Elbows: 90°, 60°, and 45° bends with smooth centerline radii to minimize airflow resistance and turbulence.
- FRP Reducers & Transitions: Concentric and eccentric duct reducers, round-to-square transitions.
- FRP Air Flow Balancing Dampers: Butterfly dampers and slide gate dampers for precision volume flow control.
- FRP Rain Cowls & Exhaust Stacks: Weatherproof exhaust cowl caps, roof curb penetrations, and bird screens.
