Confirm the protected pressure boundary<\/h3>\r\n        <p>\r\n          Start with the protected equipment MAWP, piping design pressure, pump discharge rating, heat exchanger side rating, membrane rating or downstream header pressure limit. The set pressure should protect the weakest credible pressure boundary.\r\n        <\/p>\r\n      <\/div>\r\n\r\n      <div class=\"zobai-water-card zobai-water-span-6\">\r\n        <h3>2. Identify the governing water relief scenario<\/h3>\r\n        <p>\r\n          Review pump deadhead, blocked outlet, pressure reducing valve failure, tube rupture, thermal expansion, heat input, fire exposure and seasonal isolation. The governing case may be small thermal relief or full pump relief.\r\n        <\/p>\r\n      <\/div>\r\n\r\n      <div class=\"zobai-water-card zobai-water-span-6\">\r\n        <h3>3. Use pump curve and liquid data, not normal flow only<\/h3>\r\n        <p>\r\n          Pump relief should be based on shutoff head, maximum credible flow and actual water properties. Normal operating flow may be much lower than the required relieving flow during a blocked discharge case.\r\n        <\/p>\r\n      <\/div>\r\n\r\n      <div class=\"zobai-water-card zobai-water-span-6\">\r\n        <h3>4. Review seat tightness and repeated operation<\/h3>\r\n        <p>\r\n          Water relief valves may lift repeatedly because of thermal expansion, pump cycling or control instability. Seat material, leakage requirement, blowdown, spring design and maintenance interval should be matched to service severity.\r\n        <\/p>\r\n      <\/div>\r\n\r\n      <div class=\"zobai-water-card zobai-water-span-6\">\r\n        <h3>5. Select materials for water quality<\/h3>\r\n        <p>\r\n          Clean water, potable water, brine, seawater, glycol-water, boiler feedwater and RO cleaning fluid require different materials.
