Unrivaled Performance for Heavy Industrial Water Treatment: 6" Flange Tanks
In demanding industrial environments and large commercial facilities, water treatment systems face extreme challenges. Flow rates are higher, pressures can be more intense, and system uptime is non-negotiable. Stark Water's 6" Flange Series FRP tanks are engineered precisely for these conditions.
As a specialized B2B supplier, we understand that for large-scale integrators and industrial OEMs, a robust, high-capacity tank is fundamental to system reliability. Our 6" Flange tanks are built to support the most critical water purification processes.
Engineered for Industrial Scale & Reliability
When you need a tank that can perform under pressure, our 6" Flange series offers:
- Maximum Flow & Minimal Pressure Drop
The substantial 6" Flange opening is designed for very high flow rates, significantly minimizing pressure drop across large filtration or softening media beds. This is crucial for maintaining system efficiency and throughput in industrial settings. - Heavy-Duty Flange Connection
Unlike threaded connections, the 6" Flange provides a more robust, bolted, and inherently stronger seal, ideal for larger industrial control valves and high-pressure applications. This connection method ensures superior long-term integrity and simplifies maintenance for larger systems. - Superior Structural Integrity & Corrosion Proofing
Each tank features a thick, seamless, food-grade HDPE inner liner, further strengthened by a precision-wound, high-tensile fiberglass composite. This construction guarantees **100% corrosion resistance** and the structural strength required for continuous heavy-duty use. - Built for Critical Industrial Applications
Our 6" Flange tanks are rigorously tested and validated for industrial performance:- Rated for 150 PSI (10 bar) operating pressure.
- Extensively cycle-tested to **over 300,000 cycles** to ensure exceptional longevity.
- Each unit undergoes **100% factory pressure testing** to guarantee defect-free performance upon delivery.
- (Optional: **ASME Certification** or other relevant industrial certifications, if applicable, significantly enhance trust.)
Targeted for High-Volume & Industrial Sectors
The 6" Flange series is specifically designed for the most demanding applications, including:
- Large Industrial Water Softeners & Filters
- Power Generation & Boiler Feedwater Pre-treatment
- Chemical & Pharmaceutical Processing
- Oil & Gas Industry Water Treatment
- Large Municipal & Commercial Water Facilities
