Will using shared pipelines for steam and cooling water in a reactor necessarily cause water hammer? What measures might be taken?
Drain the water from the common pipeline before introducing steam.
Not necessarily; when designing the piping, care should be taken to avoid phenomena such as irregular diameter changes or right-angle bends.
Water hammer is not necessarily generated, but the risk exists. The following measures can be taken to prevent water hammer: properly designing the pipe layout, installing water hammer arresters, controlling fluid velocity, and gradually adjusting valve openings. .
When steam and water mix directly in the pipes, water hammer is likely to occur. A soda mixer needs to be installed.
Whether water or steam appears first, the volume will change drastically, and water hammer is inevitable； It is usually required to discharge clean water or replace the steam with air before making the switch.
