Must be less than 500 mbar (50 kPa).

EN 14015 provides guidelines on how the steel plates must be formed, aligned, and welded on-site. It dictates acceptable tolerances for tank verticality (plumbness), roundness, and local peaking or banding at the welded joints. 4. Welding Procedures and Qualifications

Site-built vertical cylinders with flat bottoms. It covers both open-top and closed-top designs, including those with internal or external floating roofs.

To ensure your tank project meets proper regional compliance, it helps to narrow down the local regulatory framework. Could you tell me the tank will be installed in, the specific liquid being stored, and if you need information on seismic design requirements ? Share public link

| Feature | EN 14015 | API 650 (USA) | GB 50341 (China) | | :--- | :--- | :--- | :--- | | | Europe, international projects | Americas, worldwide | China | | Wall Thickness | Uses its own calculations, generally more conservative than API 650 | Uses the "Variable-Design-Point" method, often allowing for thinner, more economical plates | Utilizes different calculation methods, often positioned between EN 14015 and API 650 in terms of conservatism | | Edge Plate Thickness | Contains general rules, but with less detailed calculations than API 650 or GB 50341 | Provides highly detailed and prescriptive rules for design | Provides detailed rules, often in line with API 650 | | Allowable Stress | Capped at 260 N/mm² (≈260 MPa) for design simplification | Does not have a fixed cap, allowing for higher-strength, thinner-walled tanks | Includes specific high-strength steels (e.g., 12MnNiVR), pushing beyond simple caps | | Seismic/Wind | References Eurocode (EN 1998-4) for seismic design | Comprehensive, self-contained appendices with specific design maps | Includes region-specific seismic and wind load parameters | En 14015 Pdf

Official copies of the standard can be acquired directly from authorized European national standards bodies such as the British Standards Institution (BSI) , DIN (Germany) , or the ANSI Webstore . Core Parameters & Application Scope

is a harmonized European standard titled "Specification for the design and manufacture of site built, vertical, cylindrical, flat-bottomed, above ground, welded, metallic tanks for the storage of liquids at ambient temperature and above."

is a European standard that specifies the requirements for the design, fabrication, and installation of above-ground, vertical, cylindrical, flat-bottomed steel tanks used for the storage of liquids at ambient temperature and above . Key Aspects of EN 14015 Must be less than 500 mbar (50 kPa)

: Includes calculations for wind loads, snow loads, and seismic actions. 3. Comparison with Global Standards

Purchasing the PDF is only the first step. Ensuring that a tank with EN 14015 is a separate process that often involves third-party inspection bodies. Many project owners and regulatory bodies require independent verification to confirm that a tank has been designed and built according to the standard's rigorous requirements.

The standard dictates which steel grades are permissible based on the minimum design metal temperature. This prevents brittle fracture failures in cold climates. It outlines chemical composition, mechanical properties, and impact testing requirements for shell plates, nozzles, and structural components. 2. Shell Design
