FRP (Fiber Reinforced Plastic) is considered as new generation construction material for chemical process plant equipments. Fibreglass resists awide range of chemicals and temperatures, but it requires the right design, fabrication and installation to match the appropriate application.
Several resin systems suitable for various specific corrosion conditions are available. Glass fibre is available as Chopped Strand Mat, Woven Roving, Roving and Surface Veils. A simple fabrication method namely hand layup is still the most preferred method for manufacturing for Chemical Plant Equipments. Filament winding is done wherever additional load bearing requirements can be economi- cally met. Dual laminates are more in use now and are Fiber Reinforced Plastic equipments with thermoplastic corrosion resistant process face of - PP, PVC, ECTFE, FEP, PVDF provide a combination of excellent chemical resistance of thermoplastics and moderate mechanical properties of FRP.
Composites are extensively used in industrial gratings, structural supports, storage tanks, scrubbers, ducting, piping, exhaust stacks, pumps & blowers, columns, reactors etc. for acidic & alkaline environments.
