Condensate left in the line can very quickly vaporize in the presence
of a high temperature fluid such as steam. This can cause a rapid
increase in the local pressure within the valve. Condensate can come
from many sources such as left over water from a hydro test or a steam
temperature drop. It is important to clear the pipes and valves of
condensate or account for it when determining the need for over-pressure
protection.
This phenomena can cause bolt stretching and gasket damage. Check
the gasket for signs of damage. Replace if necessary. Check the bolts
for stretching or any other kind of failure and replace if necessary.
If extensive damage was caused to any part of the valve during the
leak, please contact Velan Field Engineering
Services.
