Coking anti-coking ball valve
Thread Content
In recent years, many oil refining companies have opted for coking-resistant ball valves for various components in delayed coking units, such as the oil discharge valves in coke towers, the main valves for water and steam supply, and the shut-off valves before and after the filters of the bottom removal pumps in distillation towers. These valves are quite expensive, but it is not clear what their effectiveness is Please ask the experts for guidance
Our oil drain ball valve has been in use for over two years, and the overall assessment is that its performance is poor; it often fails to function properly (this is due to an unsuitable design of the valve’s steam seal).
Ball valves are easy to use, but the electric actuators associated with them have a high failure rate; moreover, the after-sales service is not very good. A hole plate should be installed before injecting the vapor seal, otherwise energy consumption will be high. We use VELAN valves from Canada
Fisher valves could be considered; they work quite well
When dealing with high-temperature coke or pipelines that may contain coke, anti-coking ball valves are used. Imported ones are commonly used these days, but domestic ones are also of high quality. . . The price is of course very high. . . Because the base material is very expensive. . . :lol
