In today’s energy landscape, where environmental compliance, operational safety, and cost-effectiveness are of utmost importance, the infrastructure supporting petroleum storage must evolve accordingly. As petroleum products are highly volatile and environmentally sensitive, the need for advanced and efficient storage systems is critical. Shijiazhuang Zhengzhong Technology Co., Ltd (Center Enamel), a global leader in the storage tank industry, proudly delivers petroleum storage tanks equipped with external floating roofs that meet and exceed international standards.
Petroleum storage is more than simply storing fuel; it is about ensuring the long-term integrity of valuable resources while minimizing environmental impact. Our petroleum storage tanks are specifically engineered for high-performance applications in the petroleum industry. We integrate cutting-edge external floating roof (EFR) systems that are designed to float directly on the surface of the stored liquid, thus significantly reducing evaporation losses and harmful emissions.
Center Enamel designs and manufactures tanks following key global certifications and regulations such as API 650, ISO standards, and local environmental protection guidelines. With decades of expertise in tank engineering, our team utilizes advanced technologies and high-quality materials to deliver welded steel tanks that withstand harsh environments and meet rigorous industrial requirements.
Our EFR-equipped petroleum storage tanks not only meet international standards but are also customizable according to client-specific project requirements. Whether it’s for crude oil, gasoline, or other refined petroleum products, our tanks are designed to offer maximum containment security and operational longevity.
External floating roofs play a vital role in mitigating the environmental and operational challenges faced by conventional fixed-roof petroleum storage tanks. These floating roofs are engineered to float atop the petroleum surface, effectively eliminating the vapor space that typically exists in fixed-roof tanks.
This key structural difference offers multiple benefits:
Vapor Emission Reduction: By preventing the accumulation of hydrocarbon vapors, EFRs dramatically reduce the emission of volatile organic compounds (VOCs) into the atmosphere.
Fire and Explosion Risk Mitigation: With lower vapor concentrations above the liquid surface, the risk of fire and explosions is significantly minimized.
Cost Efficiency: Reduction in product loss through evaporation contributes to overall savings over time.
Regulatory Compliance: Many environmental agencies globally mandate the use of floating roofs for petroleum storage, especially in regions with stringent air quality standards.
Center Enamel’s EFR systems incorporate robust sealing mechanisms, such as mechanical shoe seals and liquid-mounted primary seals, which maintain close contact with the tank wall and product surface, ensuring airtight storage integrity. The floating decks are often constructed from aluminum or stainless steel, offering excellent corrosion resistance and long service life.
Center Enamel’s manufacturing facilities are equipped with state-of-the-art machinery for welding, coating, and quality control. We offer comprehensive solutions for welded steel tanks fitted with external floating roofs that meet client needs in capacity, material selection, and site-specific features.
Our engineering teams work closely with customers to understand the unique challenges of each project. For example, in coastal regions with high humidity and salinity, we recommend corrosion-resistant alloys and anti-corrosive coatings. In high-capacity crude oil terminals, our tanks are often designed with double-deck floating roofs and advanced drainage systems to handle large volumes securely.
Every tank we deliver is factory-inspected and quality-tested to ensure mechanical integrity, seal tightness, and conformity to applicable standards. Our tanks are designed for rapid field assembly, reducing construction timelines and costs.
Center Enamel has completed numerous petroleum storage projects globally, supplying EFR-equipped tanks for major oil refineries, depots, and distribution terminals. In Africa, we partnered with a national petroleum company to install storage tanks with aluminum dome roofs and external floating decks, greatly improving storage safety and emission control.
In Southeast Asia, our welded steel tanks equipped with EFRs were implemented in a coastal petroleum import terminal. The project required tanks resistant to typhoon-level wind loads and saline corrosion, and our engineering team delivered on every front.
Our tanks have also been deployed in remote areas of Central Asia and the Middle East, where reliable storage with low maintenance requirements is a necessity. The adaptability and robustness of our tank systems make them ideal for deployment in a wide range of climatic and logistical conditions.
Sustainability is a critical concern in petroleum storage infrastructure. As global climate goals become more ambitious, the role of emission-reducing technologies like external floating roofs becomes even more prominent.
Center Enamel is committed to environmental stewardship through innovative design. Our tanks are compatible with vapor recovery systems (VRS) and can be integrated with smart monitoring sensors for leak detection, pressure tracking, and inventory management. These digital features support operators in maintaining optimal safety and efficiency.
Furthermore, our floating roof tanks are built to be future-ready. With modular components and scalable designs, our systems allow for easy expansion or upgrades in line with new regulations or increased storage demands.
Choosing Center Enamel means partnering with a company that blends engineering excellence with a commitment to quality and sustainability. Our external floating roof petroleum storage tanks are trusted by clients across more than 100 countries for their durability, environmental performance, and cost efficiency.
We don’t just supply tanks – we deliver peace of mind, technical support, and a path toward safer, cleaner energy infrastructure.
Whether your project requires a single storage unit or a large-scale terminal installation, Center Enamel has the expertise, resources, and global reach to deliver on your vision. Trust us to elevate your petroleum storage systems with external floating roofs built to the highest global standards.
