       <div class=\"faq-content\">\r\n            Duplex 2205 and Super Duplex 2507 are commonly evaluated for offshore platform flanges due to their combination of corrosion resistance and mechanical strength. Engineers typically choose between them based on chloride severity, process media, operating temperature, and lifecycle reliability requirements.\r\n          <\/div>\r\n        <\/details>\r\n\r\n        <details class=\"faq-item\">\r\n          <summary>When should engineers choose super duplex offshore flanges instead of duplex 2205?<\/summary>\r\n          <div class=\"faq-content\">\r\n            Super duplex is often selected for more aggressive chloride environments, critical process lines, or longer design-life targets where pitting and crevice corrosion risk is higher. Duplex 2205 can be a cost-effective option for many topside services with lower corrosion severity.\r\n          <\/div>\r\n        <\/details>\r\n\r\n        <details class=\"faq-item\">\r\n          <summary>Do offshore platform flange materials need NACE MR0175 review?<\/summary>\r\n          <div class=\"faq-content\">\r\n            If the service involves sour fluids containing H2S, engineers typically review material suitability against <strong>NACE MR0175 requirements<\/strong>. The final decision depends on process composition, pressure, temperature, hardness limits, and project specification.\r\n          <\/div>\r\n        <\/details>\r\n\r\n        <details class=\"faq-item\">\r\n          <summary>What are the key risks for offshore stud bolts in platform service?<\/summary>\r\n          <div class=\"faq-content\">\r\n            Offshore stud bolts can be affected by corrosion, preload loss, coating degradation, vibration, and installation inconsistency.
