Filament Winding Tanks manufactured by Eissa Fiberglass LLC are high-performance storage solutions produced using an advanced automated computer-controlled process known as filament winding. Fabricated by winding continuous glass roving strands saturated with resin around a precision rotating mandrel at pre-calculated helix angles, these vessels attain exceptional strength-to-weight ratios that surpass traditional fabrication methods.
The automated, uniform winding process guarantees exact structural consistency, preventing resin-lean zones or porosity. Unlike metallic tanks prone to pitting, rust, and galvanic corrosion, or concrete tanks that risk stress fractures over time, filament-Winding GRP/FRP vessels provide lifelong resistance to chemical attack and thermal fatigue in both above-ground and underground installations.
Filament winding enables precise orientation of continuous glass rovings along designated hoop and helical stress paths, optimizing mechanical strength without unnecessary structural deadweight:
| Process Element | Engineering Specification & Execution |
|---|---|
| 1. Internal Corrosion Barrier | Resin-rich chemical barrier (1.2 to 2.5 mm thick) backed by C-glass surface veil and chopped strand mat (70–75% resin content) applied prior to structural winding. |
| 2. Continuous Filament Winding | Computer-controlled multi-axis carriage applying continuous E-glass rovings at optimized helix angles (typically 54.75° for balanced axial and hoop loads). |
| 3. Controlled Resin Delivery | Automated resin impregnation bath maintaining consistent 55–65% glass-to-resin ratio by weight for high tensile strength and stiffness. |
| 4. External UV & Topcoat | Parabrominated or paraffin wax-infused outer coating with high UV absorber content to counter intense solar exposure and weathering. |
| Nozzle Integration | Full-penetration compression-molded or filament-Winding composite flanges bonded with gusset reinforcements to prevent shear strain. |
Standard configuration for high-capacity liquid storage, process reactors, and dosing systems demanding high hydrostatic head strength.
Engineered for large bulk liquid transport, low-profile installations, and underground direct-burial applications.
Filament winding uses computer-controlled tension and continuous directional fiber roving, providing significantly higher glass content (55–65% vs. 30–40% in hand lay-up). This results in far higher tensile strength, thinner and lighter wall requirements, and uniform structural integrity with zero air entrapment.
Yes. By customizing the helical winding angle and adding external stiffening ribs, filament Winding vessels can be engineered for positive pressure systems as well as full negative pressure (full vacuum) scenarios without wall collapse.
Our automated mandrels can produce single cylindrical shell diameters up to 4.0 meters and lengths up to 14 meters in one piece, delivering storage volumes exceeding 30,000 US gallons (100,000+ liters) per vessel.
Yes. We integrate heavy exterior annular ribs directly into the filament Winding shell during the automated winding phase, providing high hoop stiffness to withstand soil deadloads, groundwater pressure, and live vehicle traffic.
