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

The 6" Flange Series represents the pinnacle of our heavy-duty manufacturing capabilities. Designed for critical infrastructure and industrial processes, these tanks provide the structural stability and massive flow capacity required for large-scale water treatment operations.
1. Heavy Industrial Power & Utilities
Power plants and utility stations rely on our 6" flange tanks for boiler feed water softening and cooling tower side-stream filtration. The robust flange connection ensures zero leakage under high-pressure and high-vibration industrial environments.
2. Large-Scale RO Desalination Pre-treatment
In municipal or industrial desalination plants, these tanks serve as massive multi-media filters. They handle the immense flow rates required to feed large RO trains, effectively removing particulates to protect expensive membrane elements.
3. Chemical & Petrochemical Processing
Process water in chemical plants must be free of impurities. Our FRP construction offers superior chemical resistance compared to steel, making these tanks ideal for storing or filtering aggressive process water and liquid chemical solutions.
4. Municipal Water & Wastewater Treatment
Used in community water supply systems for iron/manganese removal and arsenic reduction. In wastewater plants, they act as tertiary polishing filters before water discharge or reuse, handling continuous 24/7 operation.
Engineered for Industrial Integration
Industrial projects require more than just tanks. Do you need industrial butterfly valves, pneumatic actuators, or face piping kits?
