Water hammer in steam lines

Water hammer in steam distribution lines usually occurs during system start-up and warm-up. Therefore, this process must be carried out methodically, sequentially heating individual sections of the steam pipeline, using drain valves, bypass lines for heating and excluding sudden opening and closing of valves. In addition, steam lines should be provided for steam dehumidification using cyclone separators and condensate drainage by installing condensate pockets with condensate traps. An important condition for effective drainage is to ensure the correct slope of the pipelines, otherwise the condensate will not be able to be efficiently discharged and will accumulate, subsequently forming water hammer.

The slope should be in the direction of steam movement

ANTI-DIFFUSION LEADS TO A WATER SHOCK

Other probable causes of water hammer include the accumulation of condensate in dead-end pipelines.

Only the most common cases are illustrated here. To completely eliminate water hammer in steam pipelines, it is necessary to inspect the entire pipeline system.
