Gate Valve Leakage
Gate Valve Leakage
(OP)
A recycle pump was blocked in for a bonnet gasket repair on a warmup line when the outside suction valve bonnet gasket started leaking. A small fire ignited under the insulation blanket.
Valve was closed to block in the pump. Several hours after closing the valve, the valve leaked out of the bonnet and started a small fire. The valve continued to leak until the repair on the other valve was made and this valve was opened, unblocking the pump. After the valve was opened the leak stopped.
Anybody to tell why leakage happened from the bonnet gasket when the valve was closed.

Do you mean that pressure drop is the cause?
