Water FRP Vessel Manufacturer and Supplier in Chennai
Greeny is Chennai’s specialist in fiberglass reinforced plastic (FRP) water vessels – delivering lightweight, corrosion proof tanks that outperform traditional steel or concrete. From apartment blocks looking for compact softener housings to petrochemical plants demanding 10 bar pressure vessels, we engineer solutions that stay leak free and maintenance friendly for decades.
Why choose greeny frp vessels?
Built for Indian ConditionsChennai’s coastal humidity accelerates rust on metal tanks; our FRP construction is 100 % corrosion proof, ensuring hygiene and long service life even with saline ground water.
70 % Lighter than Steel Save on transport, crane hire, and rooftop structural support without sacrificing burst streng
High Pressure Ratings Standard vessels handle 10 kg/cm²; custom builds go up to 16 kg/cm² for demanding RO pre treatment lines.
Customizable Dimensions & Nozzles choose diameters from 8 inch to 120 inch, vertical or horizontal orientation, flanged or threaded inlets – we fabricate to your exact P&ID.
Minimal Life Cycle Cost non reactive resin means no periodic painting or cathodic protection; simple visual checks keep OPEX low.

Frequently Asked Questions
What exactly is an FRP vessel?
A factory molded tank made from layers of glass fiber and thermoset resin, offering high strength to weight ratio and immunity to corrosion.
How long do FRP vessels last?
With routine inspection of gaskets and fittings, service life is typically 15–25 years; many Greeny units remain operational past 30 years.
Are FRP vessels suitable for RO plants?
Yes. Their pressure rating and chemical robustness make them the global standard for multimedia pre filters and softeners in reverse osmosis systems.
Can I customize size and nozzle orientation?
Absolutely. Provide your footprint or GA drawing and we will fabricate to match, including side manway, sight glass, and skid mounting as required.
How do FRP vessel prices compare with stainless steel?
Capex is 30–40 % lower, and lighter weight reduces installation costs further – delivering the best cost to performance ratio over the vessel’s life.
