Workshop fabricated steel tanks - Part 2: Horizontal cylindrical single skin and double skin tanks for the aboveground storage of flammable and non-flammable water polluting liquids

This document specifies the requirements for metallic shop fabricated cylindrical, horizontal steel tanks, single and double skin for the aboveground storage of water polluting liquids (both flammable and non-flammable) within the following limits:
-   from 800 mm up to 3 000 mm nominal diameter and,
-   up to a maximum overall length of 6 times the nominal diameter and,
-   for liquids with a maximum density of up to 1,9 kg/l and,
-   with an operating pressure (Po) of maximum 1,5 bar (abs.) and,
-   where double skin tanks with a vacuum leak detection system are used the cinematic viscosity of the stored media shall not exceed 5 ´ 10-3 m2/s.
This document is applicable for normal ambient temperature conditions (- 20 °C to + 50 °C). Where temperatures are outside this range, additional requirements need to be taken into account.
This document is not applicable for the storage of liquids having dangerous good classes listed in Table 1 because of the special dangers involved.

Werksgefertigte Tanks aus Stahl - Teil 2: Liegende zylindrische ein- und doppelwandige Tanks zur oberirdischen Lagerung von brennbaren und nichtbrennbaren wassergefährdenden Flüssigkeiten

Dieses Dokument enthält Anforderungen an werksgefertigte zylindrische, liegende, ein- und doppelwandige Stahltanks zur oberirdischen Lagerung von (brennbaren und nichtbrennbaren) wassergefährdenden Flüssigkeiten mit folgenden Anwendungsgrenzen:
-   Nenndurchmesser von 800 mm bis 3 000 mm und
-   maximale Gesamtlänge bis zum 6fachen des Nenndurchmessers und
-   für Flüssigkeiten mit einer maximalen Dichte von 1,9 kg/l und
-   mit einem Betriebsdruck (Po) von maximal 1,5 bar (abs.) und
-   bei Verwendung von doppelwandigen Tanks mit einem Vakuum-Leckanzeigesystem darf die kinematische Viskosität des Lagermediums 5 ´ 10-3 m2/s nicht übersteigen.
Dieses Dokument gilt bei üblichen Ungebungstemperaturen (-20 °C bis +50 °C). Für Temperaturen außerhalb dieses Bereichs müssen zusätzliche Anforderungen berücksichtigt werden.
Dieses Dokument gilt nicht für die Lagerung von Flüssigkeiten der in Tabelle 1 aufgeführten Gefahrgutklassen wegen der von ihnen ausgehenden besonderen Gefahr.

Réservoirs en aciers fabriqués en atelier - Partie 2: Réservoirs horizontaux à simple et double paroi pour le stockage aérien des liquides inflammables et non inflammables polluant l'eau

Le présent document spécifie les exigences applicables aux réservoirs en aciers, cylindriques, horizontaux,
fabriqués en atelier, à simple et double paroi, pour le stockage aérien de liquides polluant l'eau (inflammables et
non inflammables), et compris dans les limites suivantes :
.diamètre nominal compris entre 800 mm et 3 000 mm ;
.longueur maximale d'encombrement égale à 6 fois le diamètre nominal ;
.pour les liquides présentant une masse volumique maximale égale à 1,9 kg/l ;
.avec une pression de service (p o ) maximale de 1,5 bar (absolue) ; et
.lorsque des réservoirs à double paroi, munis d'un système de détection de fuites du vide, sont utilisés, la
viscosité des liquides stockés ne doit pas être supérieure à 5 × 10 -3 m 2 /s.
Le présent document s'applique dans des conditions normales de température ambiante (-20 °C à + 50 °C).
Lorsque des températures sont en dehors de cette plage, il convient que des exigences complémentaires soient
considérées.
Ce document ne s'applique pas au stockage de liquides appartenant aux classes de matières dangereuses
énumérées au Tableau 1, en raison des dangers spécifiques engendrés.
