Overview

EN 14620-2:2006 is the CEN European Standard that specifies requirements for the metallic components of site-built, vertical, cylindrical, flat‑bottomed steel tanks used to store refrigerated, liquefied gases at operating temperatures between 0 °C and −165 °C. Part 2 of the EN 14620 series focuses on the selection of steels, design rules, fabrication, welding procedures and inspection/testing requirements for cryogenic storage tanks and their metallic parts.

Key Topics

  • Materials and temperature limits: requirements for steel selection, material classes and suitability for cryogenic service; differentiation of primary and secondary liquid containers and vapour (outer) containers.
  • Design fundamentals: design theory, maximum allowable design stresses, partial load and material factors, membrane design considerations and shell plate thickness rules.
  • Welding and procedures: qualification of welding procedures, preheat/post‑weld heat treatment guidance, tack/temporary welds, rules for 9 % nickel steels and welder/operator qualifications.
  • Fabrication tolerances: plate preparation, radius and profile tolerances, local weld deformation limits, roof and temporary attachment rules.
  • Inspection and NDT: prescribed test methods and acceptance levels including visual, dye penetrant, magnetic particle, radiographic and ultrasonic testing, vacuum box, leak testing (soap bubble, ammonia tightness), and qualification of NDT personnel.
  • Testing, fatigue and actions: requirements and informative annexes covering actions on membranes, fatigue (S‑N curves) and methodology for deriving load and fatigue curves.

Applications

EN 14620-2 is used by professionals involved in the lifecycle of cryogenic storage tanks:

  • Tank designers and structural engineers specifying metallic components for refrigerated liquefied gas storage (LNG, industrial gases).
  • Fabricators and welding supervisors implementing qualified welding procedures and production controls for cryogenic steels.
  • NDT inspectors and QA/QC teams applying inspection regimes and acceptance criteria to ensure weld integrity.
  • Plant owners, constructors and regulators verifying compliance for safety, durability and operability of site-built cryogenic tanks.

Adoption of EN 14620-2 supports consistent, safe design and manufacture of cryogenic tanks and helps mitigate risks associated with low-temperature embrittlement, fatigue and leakage.

Related Standards

  • EN 14620 series (Part 1: General; Part 3: Concrete; Part 4: Insulation; Part 5: Testing/drying/purging)
  • Referenced NDT, welding and structural Eurocodes (examples: EN 287‑1, EN 1435, EN 1712, Eurocode 3/ENV 1993 series)

Keywords: EN 14620-2, refrigerated liquefied gas tanks, cryogenic storage tanks, metallic components, site-built vertical cylindrical tanks, welding, NDT, tank design.

At design metal temperatures below –160 °C, the impact testing shall be performed at –196 °C. NOTE 1 Where austenitic steel is used, bolts may relax on cooling to sub zero temperatures. This is caused by a permanent transformation of the structure from austenitic to martensitic, which results in an increase of length. The extent of transformation increases with the applied stress. NOTE 2 Bolts that cannot be retightened after cooling should be made from steel having a stable structure, such as 25 Cr 20 Ni or nitrogen bearing austenitic steel.

Die Anforderungen an die Materialien stellen sicher, dass nur hochwertige und geeignete Rohstoffe verwendet werden, die den extremen Betriebsbedingungen standhalten. Darüber hinaus werden durch festgelegte Konstruktionsmethoden potenzielle Sicherheitsrisiken minimiert, was für die Betreiber von Kühllagertanks von entscheidender Bedeutung ist. Diese Norm ist besonders relevant für Unternehmen, die in der chemischen Industrie oder im Bereich der Erdgaslagerung tätig sind, da sie hilft, Standards zu etablieren, die den gesetzlichen Vorgaben entsprechen und das Risiko von Unfällen verringern. Insgesamt unterstützt die EN 14620-2:2006 die Schaffung sicherer und effizienter Kühllagertanks und spielt eine zentrale Rolle in der europäischen Normungspraxis für die Lagerung von verflüssigten Gasen.
