What are Underground Double-Walled Steel Storage Tanks? Overview and applications

What underground double-walled steel tanks are? ❑ An underground fuel storage tank is a robust container designed to store flammable liquids, such as gasoline, diesel, or heating oil, below the ground surface. ❑ They consist of two layers of steel, an inner tank and an outer tank, with an empty space (interstitial space) between them. Applications Petroleum Industry: These tanks are widely used for storing petroleum products, such as gasoline, diesel, and jet fuel, in refineries, fuel stations, and industrial facilities. Chemical Industry: Double-walled steel tanks are suitable for storing various...

Technical features Characteristics and norms

Technical Specifications The tank is constructed using materials that meet European standards for underground storage tanks. Common materials include corrosion-resistant steel (compliant with EN 10025 or equivalent) or reinforced fiberglass (compliant with EN 13121 or equivalent). The material selection ensures durability, resistance to corrosion, and compliance with European norms. The underground storage tank is designed as a double-wall tank, complying with European norms and regulations. The tank design considers factors such as capacity, material selection, structural integrity, and environmental...

Design norms: EN 12285-1 class A Technical Specifications Material – S235JR according to EN10025-2 carbon steel Characteristics: Horizontal cylindrical shape with double steel wall 3-inch quick-fill nozzle with clamp and lockable lid, according to DIN 28 450; Overcharging protection, according to EN 13616; Leak detection device, according to EN 13160; Level indicator with informative role, dipstick; Ventilation pipe with flame arrestor mesh; 3 DN 600 access manhole with gasket and bolted cover, provided with connectors Mechanical load limiting valve calibrated to 95% of the geometric capacity...

Double-walled steel tanks are available in a range of sizes to accommodate different storage needs. The tank's capacity adheres to European norms and may vary depending on the specific application and regulations of the country. Capacities typically range from 1000 liters to 100.000 liters. The tank's dimensions are designed to meet standard installation parameters and accommodate the required volume.

Technological production flow

Design and planning The production process begins with the design and planning phase, where engineers and designers create detailed drawings and specifications for the double-walled storage tanks. Factors such as tank capacity, dimensions, material selection, and regulatory requirements are taken into consideration during this phase.

Material Procurement ❑ Once the design is finalized, the production team procures the required materials. Common materials used for double-walled storage tanks include high-quality steel sheets, coatings, insulation materials, and accessories such as valves and fittings. ❑ It is essential to source materials from trusted suppliers to ensure the quality and integrity of the tanks. Cutting and Forming The steel sheets are cut according to the specified dimensions using specialized cutting machines. Computer Numerical Control (CNC) machines are often used for precision cutting. Eurial is using a...

The tank's construction and welding adhere to European norms and standards, such as EN 12285 or equivalent. Welding techniques and procedures comply with applicable norms, ensuring structural integrity and preventing leaks or failures. The formed steel sheets are welded together using various welding techniques such as semi-automatic laser welding ESAB to create the tank's main structure. Skilled welders meticulously join the steel sheets, ensuring strong and secure welds that maintain the tank's integrity. Additional components such as reinforcements, brackets, and flanges are also fabricated...

Inner and Outer Tank Construction ❑ The double-walled feature of the storage tank requires the construction of both an inner tank and an outer tank. The inner tank is typically made of corrosion-resistant materials or coated with specialized liners to protect it from the stored substances. These measures may include internal and external coatings or linings, cathodic protection systems, compliant with EN 12068 or equivalent, to enhance the tank's resistance to corrosion and prolong its lifespan. ❑ It is fabricated and welded separately. The outer tank provides an additional layer of protection...
