FRP Pressure Vessel Tank

 

🔹 The FRP Pressure Vessel Tank is a next-generation composite storage and filtration solution, combining the strength of fiberglass-reinforced plastic (FRP) with the chemical stability of polyethylene liners.

The 844-3072 model is suitable for small and medium-sized water treatment and filtration systems. The water treatment capacity is approximately 0.3-6 m³/hour.

Designed to outperform traditional steel pressure tanks, this vessel offers corrosion-free operation, superior pressure endurance, and 60% lower weight, making it ideal for high-demand water treatment and industrial processes.

Engineered for operating pressures up to 150 PSI (10.5 bar) and temperatures from 1°C to 50°C, the tank features a multi-layered composite structure that ensures both safety and long service life.
Its non-metallic construction prevents rust, scaling, and bacterial growth - ensuring clean, stable, and long-lasting operation across diverse fluid management systems.

 

 

 

1️⃣ Inner Liner (PE) – Food-grade polyethylene, ensuring clean water contact and zero contamination.
2️⃣ Reinforced Layer (FRP) – High-tensile fiberglass filaments wrapped with epoxy resin, providing structural strength.
3️⃣ Exterior Finish – UV-resistant gel coat that resists cracking, weathering, and discoloration.
4️⃣ Base Support – Molded FRP base ensures balance and easy integration in vertical installations.

Choosing the right pressure vessel is critical for water treatment efficiency, maintenance cost, and long-term reliability.
Here's a detailed comparison between FRP Pressure Vessel, Steel Tank, and PVC Tank, based on key engineering metrics and lifecycle performance:

Feature	FRP Pressure Vessel Tank	Steel Tank	PVC Tank
Material Composition	Fiberglass Reinforced Plastic (FRP) + PE Inner Liner	Carbon or Stainless Steel	Polyvinyl Chloride (PVC)
Weight	Ultra-light (≈60% lighter than steel)	Heavy	Very light but limited capacity
Corrosion Resistance	✅ 100% Rust-Free	❌ Prone to corrosion & scaling	✅ Corrosion-free but weak under pressure
Pressure Resistance	Up to 150 PSI (10.5 bar)	Up to 200 PSI	≤ 60 PSI
Burst Pressure	600 PSI (42 bar)	500–700 PSI	≤ 120 PSI
Temperature Range	1°C – 50°C	-10°C – 100°C	0°C – 45°C
Chemical Compatibility	Excellent – resists acids, alkalis, chlorine	Moderate – needs coating	Poor – limited chemical tolerance
Maintenance Requirement	Low – no painting or coating	High – periodic rust protection	Low – but prone to UV degradation
Lifespan (Service Years)	8–12 years	5–8 years (with maintenance)	3–5 years
Installation Flexibility	Vertical / Horizontal	Mainly Vertical	Small-scale only
Applications	RO Systems, Water Softening, Desalination, Wastewater Recycling	Industrial Plants, Boilers, Fire Systems	Domestic Water Storage
Aesthetic Appearance	Smooth, customizable colors	Industrial metallic	Basic plastic
Eco-Friendliness	♻️ Recyclable FRP composites	Non-recyclable coatings	Limited recyclability
Overall Cost Efficiency	⭐ Best balance of durability, cost, and performance	High maintenance cost	Low cost, low durability

 

Key Insights

✅ FRP Pressure Vessel Tanks offer the optimal balance between pressure capacity, corrosion resistance, and lifecycle value.
They are particularly suited for municipal and industrial water treatment systems, where both long service life and low maintenance are essential.

⚙️ Steel Tanks remain a choice for extremely high-pressure environments, but ongoing corrosion control increases the total cost of ownership.

💧 PVC Tanks are economical for low-pressure or domestic use, yet unsuitable for industrial or long-term water filtration due to structural limitations.
