Testing and analysis of relief device opening times

Discusses the findings from a previous study to determine opening times of several relief devices that may be used to provide protection on industrial heat exchanges in the event of a tube rupture on the high-pressure side. Expresses concern regarding the applicability of the findings, in particular whether tests that had targeted the tube rupture issue could be more widely applied. This study shows , through a series of tests, that concerns were well founded, recommending that there is still a need for further testing, particularly aiming at the industrial usage of relief devices.
