The weakest protected pressure boundary decides the set pressure limit.\r\n        <\/p>\r\n      <\/div>\r\n\r\n      <div class=\"zobai-comp-card zobai-comp-span-6\">\r\n        <h3>2. Use compressor maximum flow, not normal flow only<\/h3>\r\n        <p>\r\n          Relief sizing should be based on the maximum credible compressor flow at the relieving condition.
