What are the commonly used pressure test methods for fluorine-lined valves? Generally divided into hydraulic test and air pressure test.
Hydraulic test: inject water or other liquids into the fluorine-lined valve and perform pressure test to observe whether there is water leakage.
Air pressure test: inject gas into the fluorine-lined valve and perform pressure test to observe whether there is air leakage.
These are the two pressure test methods for fluorine-lined valves.
