In industrial fire protection, the reliability of a water storage system is the difference between a contained incident and a catastrophic loss. As a premier global manufacturer based in China, Center Enamel specializes in NFPA 22-compliant bolted steel tanks, providing high-performance liquid containment for municipal, industrial, and commercial fire sprinkler systems worldwide.
Combining over 30 years of engineering expertise with advanced Glass-Fused-to-Steel (GFS) and Fusion Bonded Epoxy (FBE) coating technologies, we deliver storage solutions that exceed the structural and durability requirements of AWWA D103-09 and NFPA 22.
NFPA 22 (Standard for Water Tanks for Private Fire Protection) mandates strict criteria for tank construction, suction intake, and environmental resilience. Center Enamel’s manufacturing process is vertically integrated to ensure every component meets these benchmarks.
Traditional welded steel tanks require periodic repainting to prevent corrosion—a process that takes fire protection systems offline.
● The Center Enamel Solution: Our Glass-Fused-to-Steel tanks feature a factory-applied silica coating that is chemically bonded to the steel at temperatures above 800°C. This creates an impermeable, inert surface that requires zero repainting over its 30-year design life, ensuring the tank is always "ready for service."
NFPA 22 requires fire tanks to provide a reliable, high-flow water supply without air entrainment.
● Effective Capacity: We engineer custom anti-vortex plates for every suction intake. This allows fire pumps to draw water at maximum velocity without creating a whirlpool effect, ensuring every gallon of "effective capacity" is available during an emergency.
Global projects often face extreme weather. Our engineering team utilizes Finite Element Analysis (FEA) to calculate specific shell thicknesses and bolting patterns based on local seismic zones and maximum wind speeds, ensuring structural stability from the typhoon-prone coasts of Southeast Asia to the high-altitude regions of Sichuan.
As a leading Chinese exporter, our 2024 project portfolio demonstrates our capacity to handle large-scale, international fire protection requirements:
Project Location | Configuration & Capacity | Status |
India (Industrial Zone) | 3 Units | 19.86 x 13.2 m |
Sichuan, China | 2 Units | 7.64 x 13.2 m |
Panama (Logistics Hub) | 1 Unit | 6.88 x 7.2 m |
Unlike concrete or welded tanks that require months of onsite labor, Center Enamel’s bolted steel tanks are manufactured in our ISO-certified facility in Shijiazhuang and shipped in standard containers.
● Installation Speed: A 1,000 m3 fire water tank can be assembled in as little as 10–15 days, significantly reducing onsite safety risks and labor costs.
For projects in freezing environments, we provide integrated NFPA 22-compliant heating systems and insulation. According to Chapter 16 of the standard, we ensure water temperatures remain above 5.6°C (42°F) to prevent ice damage to the tank shell and internal components.
Q: Are Center Enamel tanks certified for potable water as well?
A: Yes. Our coatings are NSF/ANSI 61 certified, making our tanks ideal for dual-purpose reservoirs that supply both drinking water and fire protection reserves.
Q: How does Center Enamel ensure quality for international shipments?
A: Every batch of steel panels undergoes rigorous testing, including Holiday Testing (1500V) to ensure zero coating defects and impact resistance testing. We provide comprehensive technical supervision for all international installations.
Q: What is the maintenance schedule for an NFPA 22 tank?
A: While NFPA 22 governs construction, NFPA 25 governs maintenance. Because of our superior GFS/FBE coatings, maintenance is limited to a 5-year internal inspection, which can often be performed via ROV (Remotely Operated Vehicle) without draining the tank.
As China’s leading manufacturer, we combine manufacturing Power with American and European engineering standards. Whether you are an EPC contractor in the Middle East or a facility manager in Southeast Asia, Center Enamel provides the documented reliability required for modern fire protection.
