Shijiazhuang Zhengzhong Technology Co., Ltd (Center Enamel) has emerged as a globally respected manufacturer of storage tanks, known especially for its high-performance welded steel tanks. With more than three decades of excellence in tank engineering, design, and on-site construction, we specialize in delivering tailor-made oil storage tank solutions that meet the most stringent requirements for durability, safety, and environmental compliance.
As a prominent welded steel tanks manufacturer, Center Enamel provides reliable and long-lasting infrastructure for clients in oil and gas, petrochemical, energy logistics, marine storage, and government sectors. Our welded steel tanks are engineered for structural strength, resistance to corrosion, and long-term storage capability—making them the solution of choice for large-volume oil storage tank projects in both remote and urban environments.
Oil storage is a critical component of the global energy infrastructure. Whether for crude oil, refined petroleum products, or specialty hydrocarbons, the storage system must maintain the integrity of the product while withstanding physical, chemical, and environmental stress over time.
Welded steel tanks play a central role in achieving this. These tanks are constructed by welding together heavy-duty steel plates—either carbon steel or stainless steel—on-site or at fabrication facilities, forming leak-proof structures that provide unmatched containment integrity. The monolithic construction offers durability, reduced maintenance needs, and adaptability for various capacities and project configurations.
The demand for long-term oil storage is growing due to a combination of factors:
Strategic energy security planning
Volatile crude oil prices
Regulatory compliance with emissions and leak prevention
Operational needs in refineries, shipping, and aviation
Welded steel tanks meet these demands by delivering custom-designed storage systems built for reliable service, even in extreme climates or chemically aggressive conditions.
Center Enamel’s welded steel tanks are designed to ensure operational stability, environmental safety, and cost-efficiency throughout their life cycle. The following features demonstrate why these tanks are preferred for long-term oil storage tank solutions:
Welded steel tanks provide robust mechanical performance that resists internal pressure from stored oil volumes and external stressors such as temperature variation, wind loading, seismic activity, and soil movement. Seamless welding ensures there are no joints susceptible to mechanical fatigue, which is vital for tanks that remain in operation for decades.
Oil products can be corrosive to unprotected steel, especially in environments with high humidity or chemical exposure. Center Enamel applies advanced corrosion protection systems such as:
Fusion-bonded epoxy coatings
Glass-fused-to-steel linings
Polyurethane and rubberized inner linings
These coatings form an impermeable barrier between the tank material and the stored oil, reducing corrosion and extending the tank’s operational life.
Leaks in oil storage systems pose severe environmental, legal, and financial risks. Our welded steel tanks feature:
Seamless welded joints for zero leakage
Optional double-walled construction for secondary containment
Integration with leak detection sensors and alarms
Compatibility with bund walls and spill control systems
Center Enamel ensures every oil storage tank meets or exceeds international standards including:
API 650 (Welded Tanks for Oil Storage)
EN 14015 (European tank design standard)
ISO 9001 and environmental ISO 14001 compliance
Whether storing heavy crude oil, refined products, or lubricants, our welded steel tanks are customizable with:
Cone roofs, domed roofs, or floating roofs
Internal floating covers for vapor control
Thermal insulation for temperature-sensitive applications
Ventilation systems, access manholes, and instrumentation platforms
Welded steel tanks from Center Enamel are deployed across a diverse range of oil storage applications. Their versatility, durability, and engineered precision make them ideal for sectors that demand 24/7 operational performance.
Refineries require massive crude oil storage capacity to buffer supply fluctuations and prepare for the refining process. Welded steel tanks are used for:
Atmospheric storage of sour or sweet crude
Heated storage of heavy oils
Integration with vapor recovery units (VRUs)
Airports require large, high-integrity storage systems for aviation turbine fuel (ATF). Welded steel tanks serve as central fueling hubs, often connected to hydrant systems. They include features like:
Floating roofs to minimize vapor losses
Fire-resistant coatings
Lightning protection and grounding systems
Chemical plants and industrial operations store specialty oils and lubricants in welded tanks that demand:
Contamination-free storage
Compatibility with heating coils
Custom nozzle arrangements and piping networks
