In the heart of modern industry, flammable liquids—from crude oil and gasoline to jet fuel, solvents, and specialized chemicals—serve as indispensable power sources and vital raw materials. However, their inherent volatility demands an exceptionally rigorous approach to containment. Safety, environmental protection, and operational continuity hinge entirely on the integrity of your storage infrastructure.
In this high-stakes environment, merely manufacturing a vessel is not enough. A "full-service" approach is critical, offering comprehensive expertise from concept to commissioning. This integrated capability defines Center Enamel (Shijiazhuang Zhengzhong Technology Co., Ltd). With over three decades of experience, we have established ourselves as a premier China Flammable Liquid Storage Tanks Manufacturer, delivering safe, compliant, and meticulously engineered solutions worldwide.
Choosing the right containment system requires precise engineering data. Center Enamel provides a full-service manufacturing approach, ensuring every tank is optimized for the specific flash point storage solutions and chemical volatility required.

In the storage of high-volatile liquids, safety is the foundation of our engineering. Center Enamel operates under a strict "Safety-First" framework, ensuring every vessel meets the world’s most rigorous industrial standards.
Our facilities and protocols are audited by global authorities to guarantee structural integrity:
● ISO 9001:2015: Quality Management System for consistent design and service.
● API 650 & API 620: American Petroleum Institute standards for welded oil storage and low-pressure containment.
● NFPA 30 Compliance: Strict adherence to the National Fire Protection Association codes for flammable liquids.
● UL 142 / UL 2085: Options for shop-built and fire-protected tank designs.
To ensure a 30+ year service life, every tank undergoes a battery of tests before commissioning:
1. Non-Destructive Testing (NDT): We use Radiographic (RT) and Ultrasonic (UT) testing to identify flaws in weld seams, alongside Magnetic Particle (MT) and Holiday Detection (1100V+) for coating integrity.
2. Structural & Leak Testing: Hydrostatic Testing confirms shell integrity, while Vacuum Box Testing ensures zero atmospheric leakage on floor and roof seams.
3. Material Traceability: Every steel plate is sourced from premium mills with full Mill Test Reports (MTRs) to ensure chemistry and strength match the stored media.
As a global leader, Center Enamel provides more than just containment; we deliver comprehensive fuel depot engineering and support for large-scale oil terminal construction.
● Advanced Flash Point Storage Solutions: We specialize in solutions tailored to your media's volatility. Whether storing Class I flammable liquids (gasoline) or Class II/III liquids (diesel), we integrate specialized vapor management and internal floating roofs (IFR) to keep vapor levels below the lower explosive limit (LEL).
● Secondary Containment & Environmental Protection: To meet SPCC and EPA standards, we offer integrated secondary containment tanks. Our double-wall storage tanks provide a "tank-within-a-tank" safety barrier with continuous leak detection.
● Efficiency in Construction: Our modular construction techniques allow for the rapid deployment of multiple tank farms, significantly reducing the "time-to-market" for energy distributors.
Center Enamel’s expansive footprint covers more than 100 countries. Our tanks are indispensable components of critical infrastructure in:
● Oil & Gas Refineries: Storing crude, gasoline, and jet fuel.
● Chemical Processing: Containing flammable solvents and intermediates.
● Airports & Power Generation: Secure storage for aviation fuel and emergency diesel generators.
With over 10,000 successful projects, including massive installations like the Namibia Drinking Water Project (4 x 44,900 m3), our capability to construct high-integrity welded tanks is proven across diverse operating environments.
Q1: What are the requirements for storing liquids with a low flash point? A: Storing Class I flammable liquids requires a combination of vapor management, ignition control, and secondary containment. According to NFPA 30, tanks must feature pressure-vacuum vents, flame arrestors, and often Internal Floating Roofs (IFR) to minimize hazardous vapor space.
Q2: Do your tanks comply with NFPA 30? A: Yes. Center Enamel’s tanks are designed and manufactured in strict accordance with NFPA 30. Our "Full-Service" approach ensures that installation, including emergency venting and containment, aligns perfectly with safety mandates.
Q3: How long is the service life of an API 650 fuel tank? A: An API 650 fuel tank manufactured by Center Enamel typically has a service life of 30 to 50 years. This is achieved through high-grade carbon steel, advanced NDT during fabrication, and high-performance internal linings.
Q4: Why are double-wall storage tanks recommended for flammable liquids? A: Double-wall storage tanks are the industry standard for environmental safety. The interstitial space between the two shells allows for continuous leak monitoring, preventing contamination and fire risks if the primary tank is breached.
Q5: What testing is required before a flammable liquid tank is commissioned? A: Every tank must undergo Hydrostatic Testing to check for leaks and settlement, alongside NDT (Radiographic or Ultrasonic) on weld seams. Vacuum Box Testing is also performed to ensure the vessel is completely gas-tight.
