Description
Industrial Dual Laminate PP FRP Pressure Vessel Manufacturer in Gujarat
Nikunj Fibre Glass is a renowned manufacturer and supplier of PP FRP Pressure Vessels (Dual Laminate Polypropylene Lined Fiberglass Pressure Tanks) based in Vapi, Gujarat. Specifically engineered for pressurized chemical transfer, corrosive liquid filtration, ion exchange columns, and gas-liquid contactors where metallic pressure vessels corrode, our dual laminate vessels provide unmatched structural reliability and total chemical resistance.
Designed in compliance with BS 4994, ASME Section X, and ASME RTP-1, each vessel features precision-molded dished ends and a filament-wound composite structural shell that provides high burst safety factors while maintaining an inert, contamination-free inner surface.
Key Features & Advantages
- Dual Laminate Integrity: Inner virgin PP liner provides seamless chemical resistance, while the outer filament-wound FRP composite shell withstands internal hydraulic pressures up to 6 Bar.
- Zero Metal Leaching: Ideal for high-purity chemical processes, pure demineralized water, and pharmaceutical intermediate transfers.
- High Fatigue Life: Filament-wound continuous fiberglass rovings absorb internal pressure pulsations without risk of stress corrosion cracking.
- Torispherical Dished Heads: Deep dished heads ensure uniform internal stress distribution and maximum hydraulic burst strength.
- ANSI 150# Flanged Connections: Fully lined PP stub ends with composite backing rings guarantee leak-proof flange jointing.
