Product portfolio overview
· Carbon steel petroleum storage tanks: Large-capacity welded carbon steel tanks designed for crude oil, refined products, diesel, fuel oil, and other petroleum liquids. Key attributes include robust wall thickness, corrosion resistance (with coatings or linings as required), and compatibility with industry-standard containment and safety features.
· LPG and pressurized liquid tanks: Pressure-rated carbon steel tanks for LPG and other pressurized hydrocarbons, integrating safe venting, relief devices, and rigorous fabrication standards to maintain integrity under pressure.
· Bolted steel tank variants (where applicable): In some applications, bolted configurations paired with epoxy or fusion-bused coatings can provide cost-efficient, modular storage options for certain petroleum products or intermediate storage needs. Center Enamel can offer design support to determine suitability.
· Ancillary systems: The company often provides integrated solutions including foundation design, insulation, fire protection interfaces, manways, ladders, ladders and stairs, access platforms, and instrumentation penetrations, ensuring a complete turnkey package.
Design and engineering approach
· Safety-first philosophy: Tank design prioritizes structural integrity under static and dynamic loads, including wind, seismic, and temperature variations, while ensuring safe access for maintenance and operation.
· Material selection: Carbon steel is chosen for its mechanical strength, weldability, availability, and cost-effectiveness, with corrosion protection strategies tailored to petroleum products. Coatings, linings, and surface treatments are selected based on service fluid, temperature, and regulatory requirements.
· Finite element analysis and calculations: Engineering workflows typically combine FE analysis with practical design codes to optimize wall thickness, stiffening, and support details, ensuring leak-tight performance and long service life.
· Customization for site and product: Center Enamel emphasizes the ability to tailor tanks for specific product characteristics (density, viscosity, sulfur content), climate conditions, and space constraints, while maintaining compliance with safety and environmental standards.
· Documentation and traceability: Comprehensive design files, material certificates, welding procedure specifications, RT/NDT results, and FAT/SAT documentation support traceability and post-delivery service.
Manufacturing capabilities
· Fabrication facilities: Center Enamel operates specialized fabrication shops equipped for heavy carbon steel welding, forming, and coating processes. The facilities are designed to manage large-diameter, high-volume vessels and ensure dimensional accuracy.
· Welding and quality systems: Weld procedures, welder qualifications, and non-destructive testing regimes are applied to ensure weld quality and structural integrity. Surface preparation and coating application are performed to ensure corrosion protection and environmental resilience.
· Coatings and coatings integration: For petroleum storage, coatings such as fusion-bonded epoxy or epoxy/polyurethane systems may be applied to extend service life and resist chemical attack. Protective linings may be used where contact with aggressive products is anticipated.
· Quality assurance: A robust QA/QC program governs material certification, machining precision, assembly alignment, hydrostatic testing, and leak testing. Quality documentation accompanies every project for client verification and regulatory compliance.
Safety and environmental stewardship
· Containment and leak prevention: Tank designs incorporate features to minimize leakage risk, including welded joints with high-quality welds, proper sealing details, access hatches, and positive containment strategies.
· Fire protection integration: Where required, tanks are designed with consideration for fire protection systems, including foam or water-based suppression interfaces and safe clearance to prevent ignition hazards near flammable liquids.
· Environmental responsibility: Lifecycle considerations include durability, coatings that resist degradation, and potential for repurposing or reconditioning to maximize asset life, reducing overall environmental footprint.
· Occupational safety: Manufacturing and on-site handling follow rigorous safety protocols to protect workers and ensure compliant commissioning, illustrating Center Enamel’s commitment to responsible operations.
