Design and manufacture of site built, vertical, cylindrical, flat-bottomed steel tanks for the storage of refrigerated, liquefied gases with operating temperatures between 0 °C and -165 °C - Part 1: General
This European Standard is a specification for vertical, cylindrical tanks, built on site, above ground and of which the primary liquid container is made of steel. The secondary container, if applicable, may be of steel or of concrete or a combination of both. An inner tank made only of pre-stressed concrete is excluded from the scope of this European Standard.
This European Standard specifies principles and application rules for the structural design of the “containment” during construction, testing, commissioning, operation (accidental included), and decommissioning. It does not address the requirements for ancillary equipment such as pumps, pumpwells, valves, piping, instrumentation, staircases etc. unless they can affect the structural design of the tank.
This European Standard applies to storage tanks designed to store products, having an atmospheric boiling point below ambient temperature, in a dual phase, i.e. liquid and vapour. The equilibrium between liquid and vapour phases being maintained by cooling down the product to a temperature equal to, or just below, its atmospheric boiling point in combination with a slight overpressure in the storage tank.
The maximum design pressure of the tanks covered by this European Standard is limited to 500 mbar. For higher pressures, reference can be made to EN 13445, Parts 1 to 5.
The operating range of the gasses to be stored is between 0 °C and –165 °C. The tanks for the storage of liquefied oxygen, nitrogen and argon are excluded.
The tanks are used to store large volumes of hydrocarbon products and ammonia with low temperature boiling points, generally called “Refrigerated Liquefied Gases” (RLG’s). Typical products stored in the tanks are: methane, ethane, propane, butane, ethylene, propylene, butadiene (this range includes the LNG’s and LPG’s).
NOTE Properties of the gases are given in Annex A.
The requirements of this European Standard cannot cover all details of design and construction because of the variet
Auslegung und Herstellung standortgefertigter, stehender, zylindrischer Flachboden-Stahltanks für die Lagerung von tiefkalt verflüssigten Gasen bei Betriebstemperaturen zwischen 0 C und -165 C - Teil 1: Allgemeines
Diese Europäische Norm enthält Festlegungen für stehende, zylindrische, standortgefertigte, oberirdische Tanks, deren zur Aufnahme der Flüssigkeit vorgesehener Primärbehälter aus Stahl besteht. Der Sekundär-behälter, falls vorhanden, darf aus Stahl oder Beton, oder aus einer Kombination von beiden bestehen. Innentanks, die nur aus Spannbeton hergestellt werden, fallen nicht in den Anwendungsbereich dieser Norm.
Diese Europäische Norm legt Grundsätze und Anwendungsregeln für die Bemessung der �Sicherheitshülle" während bei Bau, Prüfung, Inbetriebnahme, Betrieb (unbeabsichtigter Betrieb eingeschlossen) und Außer-betriebsetzung fest. Anforderungen an Zusatzausrüstungen wie Pumpen, Pumpsonden, Armaturen, Rohrleitungen, Messgeräte, Treppen usw. werden nicht festgelegt.
Diese Europäische Norm gilt für Lagertanks, die für die Lagerung von Produkten vorgesehen sind, die in der dualen Phase, d. h. in der Flüssigkeits- und Dampfphase, bei atmosphärischem Druck einen Siedepunkt unterhalb der Umgebungstemperatur haben. Das Gleichgewicht zwischen Flüssigkeits- und Dampfphase wird aufrechterhalten durch Abkühlung des Produkts auf eine Temperatur, die dem Siedepunkt bei atmo-sphärischem Druck oder einer etwas niedrigeren Temperatur entspricht, verbunden mit einem leichten Überdruck im Lagertank.
Der maximale Auslegungsüberdruck für die in dieser Europäischen Norm behandelten Tanks ist auf 500 mbar begrenzt. Für höhere Drücke kann auf EN 13445 Bezug genommen werden.
Die Tanks werden zur Lagerung großer Volumina von Kohlenwasserstoffprodukten und Ammoniak mit niedrigen Siedepunkten verwendet, die allgemein als �Tiefkalt verflüssigte Gase" (RLG) bezeichnet werden. In den Tanks werden üblicherweise Methan, Ethan, Propan, Butan, Ethylen, Propylen, Butadien gelagert (Flüssigerdgas (LNG) und Flüssiggas (LPG) sind eingeschlossen).

La présente Norme européenne spécifie les exigences relatives aux réservoirs verticaux, cylindriques, construits sur site, situés au dessus du sol et dont la cuve primaire est en acier. La cuve secondaire, le cas échéant, peut être en acier ou en béton ou mixte. La présente norme ne s'applique pas aux réservoirs dans lesquels la cuve interne est en béton précontraint.
La présente Norme européenne présente des principes et des règles d'application pour la conception de la structure du « confinement » lors de la construction, des essais, de la mise en service, du fonctionnement (y compris en cas d'accident) et de la mise hors service. Elle n'aborde pas les exigences relatives aux équipements auxiliaires, tels que les pompes, les puits de pompe, les vannes, les tuyauteries, l'instrumentation, les cages d'escalier, etc.
La présente Norme européenne s'applique aux réservoirs de stockage de produits dont le point d'ébullition atmosphérique est inférieur à la température ambiante en phase double, c'est-à-dire, liquide et gazeuse, l'équilibre entre les phases liquide et vapeur étant maintenu par mise en froid du produit à une température égale ou légèrement inférieure à son point d'ébullition atmosphérique, associée à une légère surpression dans le réservoir de stockage.
La pression maximale de calcul des réservoirs couverts par la présente Norme européenne est limitée à 500 mbarg. Pour des pressions supérieures, il est possible de consulter l'EN 13445.
La plage de fonctionnement, correspondant au gaz devant être stocké, est entre 0 °C et -165 °C. Les réservoirs de stockage pour l'oxygène, l'azote et l'argon liquéfiés sont exclus.
Les réservoirs sont utilisés pour le stockage de grands volumes de produits hydrocarbonés et d'ammoniac se vaporisant à basse température, généralement appelés « Gaz liquéfiés réfrigérés » (GLR). Les produits types stockés dans les réservoirs sont : le méthane, l'éthane, le propane, le butane, l'éthylène, le propylène, le butadiène

EN 14620-1:2006 is a European Standard that specifies the design and manufacture requirements for site built, vertical, cylindrical, flat-bottomed steel tanks used to store refrigerated, liquefied gases with operating temperatures between 0 °C and -165 °C. The primary liquid container of these tanks is made of steel, while the secondary container can be made of steel, concrete, or a combination of both. However, tanks with an inner tank made only of pre-stressed concrete are not included in this standard. This standard focuses on the structural design of the tank during construction, testing, commissioning, operation (including accidents), and decommissioning. It does not address the design requirements of ancillary equipment unless they can affect the structural design of the tank. The maximum design pressure for the tanks covered by this standard is limited to 500 mbar, and for higher pressures, reference is made to EN 13445, Parts 1 to 5. The tanks covered by this standard are used to store refrigerated liquefied gases, which are products with boiling points below ambient temperature and exist in both liquid and vapor phases. The tanks maintain an equilibrium between the liquid and vapor phases by cooling the product down to a temperature just below its atmospheric boiling point, combined with a slight overpressure in the tank. The operating temperature range for the stored gases is between 0 °C and -165 °C. However, this standard excludes tanks used for storing liquefied oxygen, nitrogen, and argon. These tanks are primarily used for storing large volumes of hydrocarbon products and ammonia with low temperature boiling points, commonly referred to as "Refrigerated Liquefied Gases" (RLGs). Some examples of products stored in these tanks are methane, ethane, propane, butane, ethylene, propylene, and butadiene, including liquefied natural gases (LNGs) and liquefied petroleum gases (LPGs). It should be noted that this European Standard does not cover all details of design and construction due to the variety of applications and individual project requirements. The properties of the gases are provided in Annex A of the standard.
