Selection of root valves for spherical tanks
Thread Content
This post was last edited by Guan Gongyu on 2015-10-12 at 12:04. The root valve is crucial for the safe operation of spherical tanks; please discuss the following: 1. The main functions of the root valve in spherical tanks and the hazards associated with potential problems in it； 2. Criteria for selecting the root valve of spherical tanks ； 3. Operating pressure of each spherical tank, storage medium, model and material of the root valve, investment, etc. Is the selection of the root valve for spherical tanks directly related to the properties and pressure of the stored medium? The design pressure of the spherical tank is 0.79 Mpa; it is used to store butane. Carbon steel valves are employed, with only one root valve. Valve: 12 inches, Class 300, RF, GEAR, BB-BG-OS&Y, API 600. Material: A216 WCB/TRIM STL/STL/13Cr. Is there a correlation between the material of the root valve and the design pressure of the tank? At what pressure level must an alloy valve be used? I hope everyone will discuss their own situations.

The selection of valves depends on the medium, design temperature, and design pressure. For media at normal temperatures, alloy steel is not necessary; it is used only at high temperatures.
Liquefied gas cylinders are not stored at high temperatures, but alloy valves are commonly used as root valves
