PSV or pressure safety valves are very common to any process industry. To protect any equipment from overpressure PSV systems are used in lines. Two types of PSVs are extensively used in process industries: a) Open discharge PSV and Closed discharge PSV. Due to any uncertain event if pressure of any equipment becomes higher than the set pressure of the installed PSV s then they pop up and reduce the system pressure. During popong up activity the PSVs exert huge reaction force over the system. During analysis of PSv connected stress systems we have to consider this reaction force. This is the main reason that PSV connected systems become stress critical. The following write up will try to explain the methods used during analysis of such systems using Caesar II.
