What is that red substance used to check the sealing condition of the valve core when reinstalling the control valve?
What location? Is there a photo? Generally, the red ones are asbestos boards; their purpose is for sealing, that is, as gaskets
There’s a major maintenance job going on today; the person in charge of monitoring the instruments is checking them. I’ve forgotten the name of that substance
It’s very likely to be a penetrant; I’m not sure if that’s correct
It should be red paint. He is the one who checks the fit
Total confusion! :L How can I not find where to post?
Yes, I asked some maintenance workers, and they said it’s called: red lead. It must be the red paint you mentioned
Red lead – used to check the radial fit of the sealing surfaces! ! It is very convenient to use, but one should not apply too much of it; otherwise, it may create an illusion of good contact between the sealing surfaces. This is especially important when the valve seat and valve body cannot be removed from the pipeline in place!
Well, it depends on where this valve is installed – is it next to the catalyst furnace, where there are many red components? Rust is also red. It’s hard to tell; it’s best to describe the environment in which the valve is located, and photos would be ideal.
It’s called Sudan Red; it is generally applied in a coat on the sealing surface of the valve seat.
