Why carbon steel for crude oil storage
· Strength, availability, and cost efficiency: Carbon steel offers high mechanical strength, widespread supply, and favorable cost profiles for large-volume tanks used in crude oil storage.
· Compatibility and coatings: With proper surface protection (fusion-bonded epoxy, specialized liners, or compatible coatings), carbon steel tanks can resist corrosive components, moisture ingress, and ambient weathering, extending service life.
· Lifecycle economics: Robust tanks with durable coatings and regular maintenance provide favorable total cost of ownership, balancing capital expenditure with long-term reliability and reduced downtime.
Center Enamel’s capabilities in crude oil storage
· Design leadership: Center Enamel leverages decades of tank design experience to tailor dimensions, shell thickness, bottom configurations, nozzles, manways, and ladder access for each project’s product profile and site constraints.
· Material and fabrication maturity: Expert handling of carbon steel plates, fittings, and welding procedures, with attention to material traceability, heat treatment, and alignment to project-specific standards.
· Coatings and corrosion protection:Utilizes industry-proven coatings such as fusion-bonded epoxy (FBE) and other protective systems suitable for crude oil environments, ensuring long-term containment integrity.
· Quality and compliance: A comprehensive QA/QC program supports material certificates, welding procedure specifications, non-destructive testing, hydrostatic testing, FAT/SAT, and third-party verification as needed.

Product and system offerings
· Crude oil storage tanks: Large-capacity welded carbon steel tanks designed for interim and long-term storage of crude oil at terminals, refinery decks, or inland facilities. Key features include robust shell and bottom welds, skid- and foundation-ready configurations, and integration with containment barriers and leak-detection systems.
· Tank shapes and configurations: Flat-bottom and sloped-bottom options to match site drainage requirements, with choice of single- or multi-compartment configurations to support different crude qualities or blending processes.
· Access and safety features: Manways, ladders, catwalks, and entry points designed to facilitate safe maintenance, inspection, and sampling activities.
· Ancillary integration: Foundations, instrumentation penetrations, vapor recovery connections, fire protection interfaces, and corrosion monitoring points to support asset integrity and regulatory compliance.
· Customization for product line optimization: Tanks can be tailored to accommodate varying API gravities, sulfur contents, and storage temperatures, with corresponding coating and insulation considerations where applicable.
Engineering and design approach
· Codes and standards alignment: Designs align with API 650/620 for storage tanks, ASME or EN equivalents for pressure considerations where applicable, and local regulatory requirements for oil storage facilities.
· Structural and thermal analysis: Finite element methods and classical design calculations optimize wall thickness, stiffening rings, saddle supports, and footing dimensions to withstand static and dynamic loads, including wind, seismic, and temperature gradients.
· Fluid compatibility and containment: Detailed assessments of crude oil properties guide nozzle sizing, venting, slosh considerations, and spill containment strategies to mitigate accidental releases.
· Safe and maintainable design: Emphasis on accessibility for routine inspections, corrosion monitoring, and future retrofits or upgrades to extend service life.
Manufacturing excellence
· State-of-the-art facilities: Large-capacity fabrication shops capable of handling heavy-gage carbon steel plates, precise forming, and welding operations required for crude oil storage tanks.
· Welding and NDE quality control: Implemented welding procedures, welder qualifications, and nondestructive testing regimes (RT, UT, MPI) to ensure joint integrity and leak-tight performance.
· Coating application: Controlled coating environments to ensure proper adhesion, film thickness, and cure requirements, with quality checks to verify coverage and coating continuity.
· Dimensional control and testing: Precision measurement during assembly, hydrostatic testing to confirm leak-tightness, and documentation to support commissioning and regulatory audits.
Safety, environment, and sustainability
· Containment and leakage prevention: Design features and manufacturing practices prioritize leak integrity, secondary containment where required, and robust construction to minimize spill risks.
· Fire protection readiness: Coordination with fire safety systems to ensure compatibility with foam and water-based suppression agents where necessary, and to maintain safe clearances around flammable inventories.
