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

What above double-walled steel tanks are? ❑ Double-walled steel storage tanks are specially designed containers used for storing various substances, such as liquids and gases. ❑ They consist of two layers of steel, an inner tank and an outer tank, with an empty space (interstitial space) between them. 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 chemicals, including acids, solvents,...

Double-walled steel tanks are available in a range of sizes to accommodate different storage needs.

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...

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. Welding and Fabrication 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 and welded onto the tank as per design specifications.

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. ❑ It is fabricated and welded separately. The outer tank provides an additional layer of protection and is constructed around the inner tank, leaving an interstitial space between them. Insulation and Coating To enhance the insulation properties and corrosion resistance of the tank, insulation materials...

Blasting ❑ The blasting process involves cleaning and polishing a surface using a high-pressure jet combined with a blasting agent. The main role of sandblasting is to deeply clean any type of material, but sandblasting is also used to prepare the surface of an object for various final finishes. ❑ The blasting process is carried out in a blasting room, equipped with high-performance SAPI/MAMUT type equipment. ❑ The blasting room has large dimensions of L16x w 6 m x h5 m. ❑ Parts requiring blasting can weigh up to 20 tones and can have the following dimensions: 15 m x 5 m x 4 m. ❑ In the...
