common causes and effects of piping vibration: a short

vibration causes dynamic stresses (fatigue) in a piping system. if this stress is more than critical value it will initiate a crack which will propagate slowly and end in the failure of the item in concern. the more fatigue sensitive places are the weld point connections

top six pump vibration problems – houston dynamic

one of the leading causes of pump vibration problems is bearing failure. this is because an estimated 10% to 30% of ball bearings are used long enough to experience normal fatigue failure. for example, an ansi pump is expected to work for 20,000 hours; but the bearings may not.
