What is hammering in steam line?
Steam hammering is the phenomenon which occurs in steam charging in the pipeline while there is a presence of condensate in the line. This is because of sudden drop in pressure of steam as it comes in contact of condensate. Steam hammers can blow flange joints and can damage piping supports and even piping itself.
How water hammer in the steam line can be avoided?
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.
Is steam hammer dangerous?
The Big Bang that you hear from your steam system can be very dangerous, even deadly, especially if its caused by water hammer. Water hammer is defined as “the unexpected release and associated shock wave of high-pressure steam/condensate”. It can cause death, severe injury, or extensive property damage.
What causes hammering in water lines?
Water hammer is usually caused in high pressure (e.g. mains pressure) water systems either when a tap is turned off quickly, or by fast-acting solenoid valves, which suddenly stop the water moving through the pipes and sets up a shock wave through the water, causing the pipes to vibrate and ‘shudder’.
When does a water hammer occur in a steam pipe?
What is water hammer? Water hammer occurs when water, accelerated by steam pressure or a low-pressure void, is suddenly stopped by impact on a valve or fitting, such as bend or tee, or on a pipe surface. Water velocities can be much higher than the normal steam velocity in the pipe, especially when the water hammer is occurring at startup.
What do you need to know about water hammer?
All That You Need to Know! What Is Water Hammer? What Is Water Hammer? Water hammer is a phenomenon that can occur in any piping system where valves are used to control the flow of liquids or steam.
What does steam hammer do to a tank?
Steam hammer occurs when un-condensed steam forms bubbles, and when these bubbles contact a pipe wall or the side of a tank, they collapse and the moving fluid produces a concussive sound. Steam hammer can be very destructive and lead to the following issues:
How is a water hammer used in condensate transport?
They ensure that pockets of steam remain small. They intercept the steam (e.g. flash steam) that is the cause of the trouble, or connect it to a different line. Wherever possible, they avoid contact between horizontal piping runs of high temperature steam and low temperature condensate.

How can water hammer be avoided in a steam plant?
Water hammer can also be avoided by preventing or resolving certain operational issues: 1 . Dangerous mix: High-pressure steam in contact with sub-cooled condensate is an unstable and potentially explosive mixture. 2 . Cooled condensate: Do not allow steam to be admitted into a line that is suspected of containing sub-cooled condensate. 3 .
