R8040-1000PSI Membrane Housing-Fully Adaptable To Special Media Environments

RO (Reverse Osmosis) Membrane FRP Pressure Vessels

Engineered specifically for demanding reverse osmosis applications, FRP (Fiber Reinforced Polymer) pressure vessels provide the critical pressurized environment required for efficient membrane filtration. These cylindrical composite structures house spiral-wound membrane elements while withstanding continuous operating pressures up to 1,000 psi.

Unlike traditional metal vessels, FRP construction offers inherent corrosion resistance against seawater, brackish water, and chemical cleaning agents. The multi-layer filament winding process creates a seamless, high-strength composite wall with exceptional hoop strength and axial stability. This eliminates rust, electrolytic corrosion, and delamination risks – extending service life beyond 25 years with minimal maintenance.

Key performance advantages include a 60% weight reduction versus steel alternatives for easier installation, NSF/ANSI 61-certified food-grade inner surfaces to prevent fluid contamination, and UV-stabilized exteriors for outdoor durability. Precision-engineered end caps with anti-telescoping protection safeguard membrane elements during pressure fluctuations.

Manufactured through computer-controlled winding technology and infrared curing processes, these vessels deliver consistent dimensional accuracy (±0.2mm) and void-free structural integrity. Every unit undergoes rigorous hydrostatic testing at 150% operating pressure and full dimensional inspection.

Ideal for seawater desalination plants, pharmaceutical water systems, industrial wastewater recycling, and microelectronics ultrapure water production, FRP pressure vessels reduce lifecycle costs by 30% compared to metal alternatives while ensuring zero fluid contamination and uninterrupted operation.

Their composite design represents the modern standard for reliable, maintenance-free membrane housing – transforming pressure containment from a maintenance liability into a system asset.

Standard Production Procedure for RO Pressure Vessels:

1. Filament Winding
