  Water Hammer in Steam and Condensate Systems

  Posted in: Engineering guides

  Causes, Risk Points and Engineering Countermeasures Water hammer in steam and condensate systems is one of the most severe operating phenomena that can occur in industrial steam installations. It is not simply pipe noise. It is a mechanical impact load that can stress valves, flanges, steam traps, heat exchangers, supports, pipework and control instruments. In practice, most water hammer incidents in steam systems are related to condensate being present where controlled steam flow is...
