Safety devices for protection against excessive pressure - Part 10: Sizing of safety valves and bursting discs for gas/liquid two-phase flow (ISO 4126-10:2024)

This document specifies the sizing of safety valves and bursting discs for gas/liquid two-phase flow in pressurized systems such as reactors, storage tanks, columns, heat exchangers, piping systems or transportation tanks/containers, see Figure 2. The possible fluid states at the safety device inlet that can result in two-phase flow are given in Table 1.
NOTE          The pressures used in this document are absolute pressures, not gauge pressures.

Sicherheitseinrichtungen gegen unzulässigen Überdruck - Teil 10: Auslegung von Sicherheitsventilen und Berstscheiben bei Zweiphasenströmung (flüssig/gas) (ISO 4126-10:2024)

Dieses Dokument legt die Bemessung von Sicherheitsventilen und Berstscheiben für Zweiphasen-Strömung (flüssig/gasförmig) in druckbeaufschlagten Systemen wie Reaktoren, Speichertanks, Säulen, Wärmetauschern, Rohrsystemen oder Transporttanks/-behältern fest, siehe Bild 2. Die möglichen Fluidzustände am Eintritt der Sicherheitseinrichtung, die bei einer Zweiphasen-Strömung auftreten können, sind in Tabelle 1 dargestellt.
ANMERKUNG   Die in diesem Dokument verwendeten Drücke sind absolute Drücke, keine Überdrucke.

Dispositifs de sécurité pour protection contre les pressions excessives - Partie 10: Dimensionnement des soupapes de sûreté et des disques de rupture pour les débits diphasiques gaz/liquide (ISO 4126-10:2024)

Le présent document spécifie le dimensionnement des soupapes de sûreté et des disques de rupture pour l'écoulement diphasique gaz/liquide dans les systèmes sous pression tels que les réacteurs, les réservoirs de stockage, les colonnes, les échangeurs thermiques, les systèmes de tuyauterie ou les réservoirs/conteneurs de transport, voir Figure 2. Les états possibles du fluide à l'entrée du dispositif de sécurité qui peuvent entraîner un écoulement diphasique sont donnés dans le Tableau 1.
NOTE          Dans le présent document, les pressions sont exprimées en pression absolue, et non pas en pression manométrique.
