En 14015 tanks are vertical, flat-bottomed storage tanks designed for the above-ground storage of low-pressure liquids. Built in accordance with the European EN 14015 standard, these tanks meet strict guidelines on structural integrity, materials, welding, and testing. this makes them ideal for applications where safety, durability, and compliance are critical.
At Gpi Tanks XL, we construct our EN 14015 tanks entirely from stainless steel — including grades such as 304(l), 316(l), duplex, and super duplex. stainless steel provides superior corrosion resistance, requires no internal coatings, and reduces long-term maintenance costs. it also supports circular use and sustainability targets thanks to its full recyclability.
Custom EN 14015 storage tanks: roof types, heating and
insulation
Whether you need storage for fuels, process water, bio-based feedstocks, or chemicals, our EN 14015 tanks are engineered to meet strict European standards while remaining fully customizable to your project. we offer a range of design options including various roof types (self-supporting, conical, or floating), heating coils, insulation systems, and access platforms.
Thanks to our in-house engineering and modular production methods, we can deliver tanks from our own facility or construct them on site, ensuring seamless integration into your process from design to installation.
EN 14015 tanks for terminals, chemicals, bioenergy and
water
EN 14015 tanks are used across all the industries we serve. In the petrochemical and oleochemical sectors, they provide safe storage for volatile substances, solvents, and feedstocks. Tank terminals rely on them for the bulk storage of fuels, base chemicals, and intermediates. In the bioenergy sector, they are used for storing feedstocks and digestate, as well as in thermal buffer applications. In the water industry, EN 14015 tanks are suitable for both process water and wastewater. The pulp and paper sector uses them in auxiliary processes such as utility water and chemical storage. While EN 14015 tanks serve a broad range of applications, other tank standards may apply when it comes to hygienic or food-grade storage in the food industry.
Benefits of stainless steel EN 14015 storage tanks
Our EN 14015 tanks are designed with durability, safety, and efficiency in mind. thanks to their stainless steel construction and fully custom design, they offer a reliable long-term solution for atmospheric storage across a wide range of industries. key benefits include:
- Fully compliant design: Built to meet strict European standards for above-ground atmospheric storage (EN 14015).
- Corrosion-resistant and low-maintenance: Constructed from high-grade stainless steel for extended service life without the need for coatings or frequent maintenance.
- Tailored to your process: Available in a wide range of diameters and heights, up to 30 metres, depending on your site and volume requirements.
- Safety-first approach: Engineered for structural integrity and safe operation, from installation to long-term use.
- Versatile applications: Suitable for storing everything from fuels and chemicals to water and select food-grade liquids, though for hygienic or food-grade applications, alternative tank standards may be more appropriate.

FAQ
What is an EN 14015 tank?
An EN 14015 tank is a vertical, flat-bottomed, welded steel tank for the above-ground storage of liquids at low pressure. The European standard EN 14015 sets requirements for design, materials, welding, inspection and testing. Gpi Tanks XL builds EN 14015 tanks entirely in stainless steel
What is the difference between EN 14015 and API 650?
Both standards cover vertical, cylindrical, above-ground welded storage tanks. EN 14015 is the European standard and is common in European projects, while API 650 is the American Petroleum Institute standard used worldwide in oil, gas and petrochemicals. The choice usually depends on project location, client specification and local
regulations. Gpi Tanks XL designs and builds to both standards.
Which liquids can be stored in an EN 14015 tank?
EN 14015 tanks are used for fuels, chemicals, solvents, bio-based feedstocks, digestate, process water and wastewater. For hygienic or food-grade storage, other tank standards and a hygienic tank design are usually more appropriate.
