Issues with Mechanical Cycle Testing in Static Applications Involving Stiction

Recording Date: February 2017

In an industrial setting such as a chemical plant, oil refinery or a deep sea oil rig, there are safety instrumented systems in place which are designed to promptly bring about a safe shutdown of a process if certain hazardous conditions are detected. Such safe shutdowns frequently involve isolating a process fluid flow, often accomplished by the use of an ESD (Emergency Shutdown) valve. If the ESD fails dangerously, when a hazardous condition necessitating a shutdown occurs and the ESD does not perform its function when required, the worst case consequences can be catastrophic. To insure a safe process, each individual part of the process is looked at in depth to analyze the failure rate and failure mode data for each component in a safety instrumented function as a safety lifestyle. This webinar will look at the cause and effects of parts on an ESD binding or sticking and what that might do to your process.
