Mechanical Component Failure Rates - Static vs. Dynamic Operation

Recording Date: March 2014

The failure rates of certain mechanical components used in solenoid valves, actuators, and valves vary substantially depending on operation. For example, seals such as o-rings have fundamentally different failure modes when used in applications with frequent movement (dynamic) versus applications with infrequent movement (static). exida has accumulated over sixty billion unit operating hours of field failure data primarily from the process industries which was used in recent mechanical failure research. This webinar explains some results from this recent exida research where failure rates and failure modes of several mechanical components were established. This seminar is useful for anyone planning proof testing for mechanical SIF devices and anyone who wants to understand field failure data for mechanical devices.
