The Phenomenon of Water Hammer
What is Water hammer?
Steam lines are insulated mainly to reduce radiation heat loss from pipe surface and also for personal protection. However, even in a well insulated steam line, radiation losses are typically 3%. This means that about 3% of the steam quantity flowing through the pipe condenses in the steam pipe lines. This condensation starts as soon as steam exits the boiler.
Steam and condensate contained in the pipeline travel together. This is two phase flow. Steam occupies the major volume of the pipe and pulls condensate at a velocity equal to itself.
As the condensate gets pulled along with steam at a high velocity, it forms a slug. Water hammer is the phenomenon caused by this slug of condensate that strikes the pipe walls, elbows, pipeline accessories at high velocity. Repeated hammering of this slug of water results in damaged pipelines and pipeline accessories.
