Selection of Corrosion-Resistant Valves for High-Temperature Environments
Thread Content
I have a client who needs valves to operate at temperatures of 400–450 degrees, with a pressure of 40 kilograms. The medium in question contains some solid particles and is corrosive. What material would be suitable for such valves? Since the client requires zero leakage from the valves, they want them to achieve zero leakage both on the inside and outside over a period of 2–3 years.
The media are hydrocyanic acid and hydrogen sulfide, along with some solid materials
Material 321, I guess; the ball valve will work
What are the valve types for WC6/WC9? Ball valves, gate valves, globe valves. It is also necessary to consider how large the particles are. This substance is very dangerous; it is hydrocyanic acid, also known as cyanogen or hydrogen cyanide. The molecular structure features carbon atoms forming bonds using sp hybridized orbitals, with carbon-nitrogen triple bonds present; the molecule is polar. It can inhibit respiratory enzymes, leading to cellular asphyxiation; it is highly toxic
