Selection of safety valves for steam pipelines
Thread Content
How to select a safety valve for a steam pipeline? The diameter of the steam pipeline is DN125, and the temperature and pressure of the steam inside the pipeline are known. How should a safety valve be chosen in such cases? How to calculate the size of a safety valve? Please provide a design approach, or process, along with the relevant standards. Thank you

API STD 520-I-2014 – Sizing, Selection, and Installation of Pressure-Relieving Devices in Refineries, Part I—Sizing and Selection. 2. GB/T 12241-2005 – Safety Valves – General Requirements. 3. GB 150-2011 – Pressure Vessels
Calculate it according to GB 150. There are also small software tools for calculating safety valves available on the forum that you can download and try out
For chemical processing units, reference can also be made to HG-T 20570.2-95 \"Installation and Selection of Safety Valves\"
The main consideration is the amount of steam released; this amount cannot be equal to the total amount of steam
You provide the manufacturer with the starting pressure, and they can calculate it for you
Is the poster from Zichuan, Shandong? ?
Bro, where’s the software? Please provide a connection, thank you
