  • Water Hammer: Causes, Effects and Solutions

    Water hammer can be defined as follows-. Water hammer is a pressure surge or wave caused when a fluid (usually a liquid but sometimes also a gas) in motion is forced to stop or change direction suddenly (momentum change). As soon as steam leaves the boiler, it starts losing heat. As a result, steam stats condensing inside the pipe work.Learn More
