Lesca Tech manufactures high-performance FRP (Fiberglass Reinforced Plastic) pressure vessels engineered for demanding applications in water treatment, desalination, and industrial chemical processing. Our vessels are designed to provide a high strength-to-weight ratio, ensuring reliable performance under significant internal pressures while remaining completely immune to electrochemical corrosion.
Precision vessel engineering
We utilize advanced manufacturing techniques to ensure each vessel exceeds industrial safety and performance standards.
CNC Filament Winding
Our vessels are fabricated using continuous filament winding technology. This allows for precise control of glass fiber orientation, maximizing the vessel's hoop and longitudinal strength to contain high internal pressures.
Composite Structural Integrity
By combining high-grade epoxy or vinyl ester resins with E-glass reinforcements, we create a composite structure that is monolithic, leak-proof, and capable of withstanding cyclic pressure loading over a long service life.
"The FRP pressure vessels provided by Lesca Tech for our RO desalination plant have shown zero signs of corrosion despite the high salinity levels. Their lightweight design also made installation much faster and safer."
Why choose our pressure vessels
We offer a technologically superior alternative to heavy, corrosion-prone metallic pressure vessels.
High Pressure Performance
Our standard vessels are rated for working pressures up to 10 Bar (150 PSI), with custom designs available for higher requirements including surge handling.
- Burst factors exceeding 4:1
- ASME RTP-1 design consistency
- Hydro-tested at 1.5x design pressure
Zero Maintenance Design
Unlike steel vessels, FRP does not require internal coating, external painting, or cathodic protection, significantly reducing the Total Cost of Ownership (TCO).
- UV-Resistant External Gelcoat
- Potable Water Safe Internal Liners
- Lightweight (1/4 weight of steel)
FRP Pressure Vessel FAQs.
Our standard industrial vessels are designed for a working pressure of 5 to 10 Bar. However, we can custom-engineer vessels to handle pressures up to 15 Bar for specialized process requirements.
Yes, our design and fabrication processes follow BS 4994, ASME RTP-1, and ASTM D3299 standards to ensure maximum safety and reliability in pressurized applications.
Absolutely. FRP is the preferred material for saltwater applications as it is completely immune to chloride-induced corrosion, making it ideal for desalination and offshore plants.
We offer both vertical and horizontal orientations with various end configurations (Flat, Dish, or Conical). Sizes range from small 200mm diameter housing up to large 4000mm diameter process vessels.
