Will water hammer occur if there is a leak in the condensate line?

I read a document regarding the recovery of condensate water in chemical plants; it mentioned that if there is a leak in the condensate line, it can cause local flashing and resulting water hammer. I don’t quite understand this passage. If anyone knows, please explain why pipeline leaks can cause cavitation. Thank you; let me know once you know
If the pressure in the leaked condensate line drops suddenly, part of the water in the condensate will instantly evaporate into steam; this process is known as flashing. In a closed system, the rapid generation of steam can lead to a swift increase in pressure. If there is intense physical interaction with unevaporated water, water hammer may occur, which can cause damage to pipes and equipment. .
This is likely caused by steam condensate from multiple streams at different pressures flowing into the same pipe; temperature differences can also be a factor, and severe leakage in individual steam traps can likewise lead to this issue
How can condensate leakage cause flashing and water hammer?
The information provided is not precise; it doesn’t clearly state what was leaked and where
After a leak occurs, as the pressure in the piping system drops, some of the fluid flashes into steam; as a result, the pipeline downstream of the leak point becomes a two-phase flow of vapor and liquid, which in turn causes water hammer.
