How Can Flashing Damage Be Contained?

1.	How Can Flashing Damage Be Contained?
Answer» Flashing cannot be eliminated in the valve – if the downstream pressure is less than the vapour pressure then flashing will occur. To minimise the damage:- Hard FACE trim (using hard facing materials such as Stellite, or TUNGSTEN CARBIDE) Use more erosion RESISTANT body material Increase size of valve, thus reducing the velocity Use angle valve – FLOW over plug Flashing cannot be eliminated in the valve – if the downstream pressure is less than the vapour pressure then flashing will occur.

Answer»

Flashing cannot be eliminated in the valve – if the downstream pressure is less than the vapour pressure then flashing will occur.

To minimise the damage:-

Hard FACE trim (using hard facing materials such as Stellite, or TUNGSTEN CARBIDE)
Use more erosion RESISTANT body material
Increase size of valve, thus reducing the velocity
Use angle valve – FLOW over plug

Flashing cannot be eliminated in the valve – if the downstream pressure is less than the vapour pressure then flashing will occur.
