Taking process safety to the next level

Page last modified
April 11 2024

Data, and therefore information, changes in time and context. Operating conditions, material properties and contaminants, equipment characteristics, and processing sequences all impact the validity of data for a specific use.

Of the hundreds or thousands relief valves used in process installations, the design criteria are sometimes unknown and more often, we don’t know if the original design specifications can still be used to comply with current laws and legislation, safety standards, etc.

Re-design and re-engineering of the relief valves significantly enhances the process safety!
