Determination of an optimum testing and inspection interval for pressure safety valves

Abstract

Thos masters thesis work tries to examine the current procedures used for testing pressure safety valves, and the bench mark used that are used in defining an inspection and testing interval for pressure safety valves. I have started by describing some basic elements of the design of safety valves, then go on to look at how these valves are tested. I have also examined the current criteria most owners of the pressure safety valves use in setting up their maintenance programs. The aim of this thesis in the end is to try and modify the current intervals being used in the oil and chemical industries today so as to cut down unwanted cost, guaranty the safety of personnel, and safe guard against any form or accidents in the plant. This thesis shows a conservative approach that is also in line with approved standards that can be used for setting an optimum inspection and testing interval.
