is the primary European standard governing the design, fabrication, and inspection of site-built, vertical, cylindrical, above-ground, welded steel tanks used for storing liquids at ambient temperatures or above. It superseded the older British standard
- Site-built, meaning they are constructed on-site rather than being prefabricated in a factory
- Vertical, with a cylindrical shell and a flat bottom
- Used for oil and gas storage, including tanks for process, storage, and terminal applications
Fabrication and Welding:
Strict guidelines are set for welding processes and non-destructive testing (NDT), including radiographic and ultrasonic inspections. En 14015 Pdf
Roof Structures:
Covers fixed roofs (cone or dome) and requirements for venting to prevent over-pressure or vacuum collapse. is the primary European standard governing the design,
4.1 Design by Rule (not by Analysis)
- Steel grades: S235, S275, S355 (to EN 10025) or equivalent with specified toughness.
- Impact testing: Required if design temperature < 0°C or thickness > limits.
- Corrosion allowance: Specified by purchaser (typically 1.5–6 mm).
- Electrodes and filler metals: Must match base metal mechanical properties.
