Réservoirs verticaux à toit flottant API 650

Product Structure

• Tiered Cylindrical Shell: A high-strength body composed of multiple horizontal rings of precision-welded steel plates for uniform pressure distribution.

• Reinforced Fixed Roof: A heavy-duty conical or dome-shaped roof designed to protect contents from environmental elements and prevent vapor loss.

• External Safety Infrastructure: Includes perimeter guardrails on the roof and integrated spiral or straight-run staircases for safe operator access.

• Heavy-Duty Foundation Base: A reinforced concrete or asphalt sand pad that provides a stable, level surface for the massive weight of the tank.

• System Nozzles & Manways: Large-diameter access manways at the base and various flanged ports for filling, draining, and sensor integration.

Product Advantages

• Massive Storage Efficiency: Vertical orientation allows for the storage of millions of liters of fluid while occupying a relatively small geographical footprint.

• Superior Structural Durability: Built with high-tensile carbon steel, featuring multi-layer welding to withstand internal hydrostatic pressure and external wind loads.

• Site-Specific Customization: As these tanks are field-erected, they can be customized in height and diameter to fit the specific constraints of your industrial site.

• Maintenance Accessibility: Integrated staircases and top-level walkways allow for easy periodic inspections and maintenance of sensors and valves.

• Corrosion Protection: Can be finished with specialized internal linings and external epoxy coatings to handle aggressive chemicals and outdoor exposure.
