Are fluorinated-lined valves resistant to negative pressure?
Thread Content
Can fluorinated-lined valves withstand negative pressure? The medium is chlorine, with a negative pressure of 1 kilogram – can fluorinated-lined ball valves handle this?
Fluorinated-lined valves must not be used in environments with negative pressure, as this will cause the lining material to be flattened
Fluorinated lining ball valves cannot be used in negative pressure conditions; when used in such environments, removing the valve reveals small bulges in the areas where the fluorinated lining is present.
Negative pressure can cause the lining to separate from the steel billet, resulting in bulging
Actually, you all have overlooked a key temperature parameter; if the temperature is not high, there is no problem with steel-lined fluoroplastic
Is the lining designed to withstand chlorine corrosion?
At a temperature of 100 degrees, I also took this into consideration and used PFA
Agree to use PFA-lined material, with a durable temperature range of -80~260℃
