FprEN ISO 4126-10 防止过压的安全装置 第10部分：气/液两相流安全阀和爆破片的尺寸 (ISO/FDIS 4126-10:2023)
Safety devices for protection against excessive pressure - Part 10: Sizing of safety valves and bursting discs for gas/liquid two-phase flow (ISO/FDIS 4126-10:2023)
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.
