We focus on delivering solutions that integrate superior structural strength, advanced internal linings and corrosion protection systems, specialized features for fluid heating and separation, and strict adherence to major international construction codes. Through rigorous quality control, mastery of automated welding techniques, and depth of material science knowledge, our Welded Steel Tanks are essential assets of maximum reliability, purity maintenance, and long term service life, supporting the crucial, environmentally responsible process of lubricant recovery and re-use globally.
The lifecycle of recycled oil fluid involves various stages—from initial contaminated collection to purified, finished product storage—each presenting distinct engineering and purity challenges. As a specialized Carbon Steel Recycle Oil Fluid Storage Tank Manufacturer, Center Enamel addresses these demands precisely.
Fluid Heterogeneity and Separation: Initial collected used oil is a heterogeneous mix containing water, solids, solvents, and fuel, often requiring pre-treatment and settling. The tanks must be designed to accommodate phase separation and include features (like sloped bottoms and draw-off ports) to facilitate the removal of water and sludge.
Corrosion from Impurities: The collected oil contains acidic byproducts and contaminants that are highly corrosive to the carbon steel structure, especially in the water-oil interface. Comprehensive internal corrosion defense, often involving specialized linings, is non-negotiable.
Viscosity and Thermal Requirements: During the re-refining process, fluids may require heating (for separation, purification, or pumping). The tank structure must be engineered to safely and efficiently integrate heating coil systems and insulation provisions without compromising structural integrity during thermal cycling.
Purity Preservation of Finished Product: Once oil is re-refined, it is a high-value, high-purity product. The storage tanks for the final product must prevent any re-contamination, often requiring internal linings and robust sealing mechanisms.
Structural and Regulatory Compliance: All tanks must comply with recognized international standards. Large receiving and storage tanks adhere to API 650, while pressure-rated separation vessels may follow API 620. Furthermore, strict environmental compliance governs all stages of handling waste and re-refined products.
Our engineering approach centers on providing this combination of structural endurance, advanced thermal and purity features, and verifiable quality assurance through our mastery of Welded Steel Tanks fabrication
The manufacturing process for Center Enamel's Carbon Steel Recycle Oil Fluid Storage Tanks is a highly specialized operation, focused on supporting separation, purity, and long-term durability against corrosive recycled streams.
The tank's internal configuration is engineered to support the physical separation and conditioning of the recycled fluids.
Sloped Bottom and Multi-Port Draw-Off: Tank floors are fabricated with a precise sloped bottom leading to a dedicated low-point sump and separate ports at different elevations. This allows operators to efficiently and precisely draw off water, sludge, or specific oil phases that settle during the holding period, which is critical for pre-treatment.
Internal Lining Systems: Due to the wide array of contaminants and acidic residues in used oils, the interior of the Carbon Steel Recycle Oil Fluid Storage Tank receives specialized, chemically resistant internal linings. This coating isolates the carbon steel from the corrosive mixture, drastically extending the tank's operational life and maintaining purity for finished products.
Filtration and Agitation Integration: The tanks are designed with reinforced nozzles and structural supports to accommodate continuous offline filtration systems, as well as potential internal mechanical mixers or agitation systems used in specific reprocessing steps.
Efficient recycling often relies on precise temperature control for viscosity and phase separation.
Integrated Heating Systems: We specialize in the fabrication and structural integration of internal heat exchange systems, including the welding of steam or electric heating coils or panel coil systems directly onto the tank walls and floor. The structural integrity is maintained despite the thermal load and cycling, ensuring the carbon steel remains structurally sound.
Insulation Provisions: The tank exterior is fabricated with robust, pre-engineered attachment points to accommodate external thermal insulation and weather jacketing. This prevents heat loss and ensures efficient viscosity control for thick oil streams being processed or stored in colder climates.
Structural resilience and protection from the elements are paramount for large industrial assets.
API 650 Adherence and NDT Verification: Large storage tanks are built to API Standard 650. Our advanced automated welding systems ensure continuous, full-penetration, defect-free seams. Every critical weld on the Welded Steel Tanks is verified using Non Destructive Testing NDT—such as ultrasonic testing and pressure testing—to confirm monolithic structural integrity.
Aluminum Dome Roofs: For large capacity Carbon Steel Recycle Oil Fluid Storage Tanks (particularly atmospheric holding tanks or final product storage), we integrate Aluminum Dome Roofs. These lightweight, self-supporting geodesic structures provide a superior, corrosion resistant seal over the tank. The Aluminum Dome Roofs prevent the ingress of rainwater and debris, which is critical for maintaining the purity of the re-refined product and minimizing the volume of waste water handled at the facility.
Secondary Containment and Spill Control: Where required by environmental regulations (e.g., for initial collection tanks), we fabricate double wall designs or integrate features compatible with external dike systems, ensuring comprehensive spill prevention.
Center Enamel’s specialized storage solutions are integral to the circular economy of lubricants and fuels:
Used Oil Collection Depots: Large-capacity tanks used for initial bulk receiving and holding of heterogeneous used oil from various sources, requiring robust anti-corrosion features.
Re-Refining Facilities: Tanks used at various stages of the reprocessing chain: solvent extraction, hydrogenation, fractionation, and final product blending, often requiring integrated heating and agitation systems.
Industrial Waste Oil Management: Storage of separated or pre-treated industrial waste oils (like quench oil or rolling oils) before shipment or further processing.
Finished Recycled Product Storage: High-purity tanks for holding the final re-refined base oils and lubricants, requiring non-reactive internal linings and superior sealing mechanisms.
