In the vast and intricate global energy ecosystem, the seamless flow of crude oil from extraction sites to refineries and, ultimately, to markets, hinges on robust and reliable storage infrastructure. Welded Carbon Steel Crude Oil Storage Tanks are the indispensable pillars of this system, providing the immense capacity, structural integrity, and unwavering safety required for this vital commodity. For industries demanding the highest standards of engineering and compliance in crude oil containment, Shijiazhuang Zhengzhong Technology Co., Ltd, universally recognized as Center Enamel, stands as a preeminent and Specialized China Welded Carbon Steel Crude Oil Storage Tanks Manufacturer. With over three decades of dedicated experience, Center Enamel leverages unparalleled expertise and state-of-the-art facilities to deliver API 650 compliant, highly efficient, and cost-effective crude oil storage solutions that form the backbone of global energy supply chains.
The strategic choice of carbon steel in a welded configuration for crude oil storage is fundamental to meeting the industry's unique demands for capacity, durability, and safety. Crude oil, a high-volume and often volatile substance, necessitates containment solutions that are not only immensely strong but also absolutely secure.
The distinct advantages of Welded Carbon Steel Crude Oil Storage Tanks are compelling:
· Exceptional Structural Strength and Immense Capacity: Carbon steel provides an optimal balance of strength, ductility, and cost-effectiveness, making it the ideal material for constructing large-scale tanks. The inherent strength of the material, combined with precise welding techniques, allows for the creation of seamless, monolithic structures capable of holding hundreds of thousands of cubic meters of crude oil. This massive scale is critical for strategic petroleum reserves, major crude oil terminals, and large refinery operations.
· Absolute Leak Prevention and Enhanced Safety: The welded construction of these tanks eliminates bolted flanges and gaskets, which are common points of potential leakage in other tank types. This seamless integrity is paramount for crude oil, where spills can lead to catastrophic environmental damage, significant economic losses, and severe safety hazards. Adherence to strict welding procedures ensures absolute leak tightness, crucial for environmental protection and operational safety.
· Optimal Compatibility with Crude Oil: Crude oil is generally non-corrosive to carbon steel, making it a highly compatible and cost-effective material choice. This compatibility ensures the long-term integrity of the tank without requiring expensive internal linings, while maintaining the quality of the stored crude.
· Compliance with API 650 – The Global Standard: The American Petroleum Institute (API) Standard 650, "Welded Tanks for Oil Storage," is the universally adopted benchmark for the design, fabrication, erection, and inspection of atmospheric storage tanks. Welded Carbon Steel Crude Oil Storage Tanks are meticulously engineered and constructed by Center Enamel to meet or exceed these rigorous requirements, guaranteeing compliance with international safety, operational efficiency, and environmental regulations.
· Versatile Roof Options for Volatility Control: Depending on the volatility of the crude oil being stored and environmental regulations, these tanks can be designed with various roof types. Fixed cone or dome roofs are suitable for less volatile crude. However, for highly volatile crude oil, internal or external floating roofs are utilized to minimize evaporative losses, reduce emissions, and enhance fire safety by eliminating the vapor space.
These attributes collectively make Welded Carbon Steel Crude Oil Storage Tanks the most trusted and widely adopted solution for secure, efficient, and compliant crude oil containment globally.

1. State-of-the-Art Manufacturing Facilities: Our expansive production base is equipped with the latest advancements in heavy steel fabrication technology specifically optimized for large-scale tank construction. This includes highly automated welding systems, such as submerged arc welding (SAW) for longitudinal and circumferential seams and automatic Flux-Cored Arc Welding (FCAW) for vertical seams. These automated processes ensure consistent, high-penetration, and virtually flawless welds, crucial for the integrity of Welded Carbon Steel Crude Oil Storage Tanks and strict API 650 compliance. Precision CNC plasma and laser cutting machines guarantee accurate plate preparation to the exacting tolerances required by API 650.
2. Rigorous Material Sourcing and Traceability: Every Welded Carbon Steel Crude Oil Storage Tank from Center Enamel begins with superior materials. We employ a strict material sourcing protocol, utilizing only high-grade carbon steel plates (e.g., ASTM A36, A283 Gr. C, A516 Gr. 70, A537 Cl. 1) that are fully traceable from the mill to the final tank assembly. This ensures that every component's mechanical properties and chemical composition meet the precise specifications required by API 650 for crude oil service, especially crucial for varying temperatures and pressures.
3. API 650 Compliant Fabrication and Welding Procedures: Our fabrication processes are meticulously engineered to conform to every requirement of API 650. This includes:

o Certified Welders: Our welders are rigorously tested and certified to API and ASME standards, possessing the specialized skills required for the complex welding of large-scale Welded Carbon Steel Crude Oil Storage Tanks.
o Heat Treatment: Where mandated by API 650 for specific material thicknesses or service conditions, pre-heating and post-weld heat treatment (PWHT) are meticulously performed to enhance material properties and mitigate residual stresses, ensuring maximum durability.
4. Comprehensive Quality Control and Non-Destructive Testing (NDT): Center Enamel implements an extensive quality control program that consistently meets and often exceeds API 650 requirements. For every Welded Carbon Steel Crude Oil Storage Tank, NDT is performed by certified personnel, including:
o Radiographic Testing (RT/X-ray): For critical welds to detect internal flaws.
o Ultrasonic Testing (UT): For volumetric examination of welds.
o Magnetic Particle Testing (MT) & Liquid Penetrant Testing (PT): For surface flaw detection on welds.
o Vacuum Box Testing: Crucially performed on tank bottoms to ensure absolute leak tightness, vital for preventing environmental contamination.
o Dimensional Inspections: Precise checks of shell diameter, height, plumbness, roundness, and nozzle orientations throughout fabrication and erection to ensure structural integrity and API 650 compliance.
5. Hydrostatic Testing: As a mandatory requirement of API 650, every completed Welded Carbon Steel Crude Oil Storage Tank undergoes a full hydrostatic test. This involves filling the tank with water to its design level, allowing for a thorough verification of its structural integrity and leak-tightness under the intended operational pressure.
6. Integrated Quality Management System: Our adherence to ISO 9001:2015 provides a robust framework for our overall quality management system, ensuring consistent processes, continuous improvement, and the delivery of high-quality products that meet client expectations and global standards.
