Dangers of water hammering in steam lines
WebApr 11, 2024 · The most important way to prevent water hammer is to remove the water from the steam lines before passing the steam again through them. Water is removed from the steam lines using drain connections. All the water should be drained out to make the lines clear. Once this is done, the steam valve should be opened very slightly (cracked … WebMar 1, 2024 · Water hammer is a phenomenon that can occur in any piping system where valves are used to control the flow of liquids or steam. Water hammer is the result of a pressure surge, or high-pressure shockwave that propagates through a piping system when a fluid in motion is forced to change direction or stop abruptly.
