Ismail Flanges, a leading manufacturer and supplier located in Jakarta, Indonesia, specializes in high-performance Duplex Steel RTJ Flanges. Renowned for their exceptional quality and precision engineering, these flanges are crafted to meet rigorous international standards for critical applications. The Duplex Steel RTJ (Ring Type Joint) Flanges from Ismail Flanges provide outstanding corrosion resistance, impressive strength, and dependable sealing in high-pressure and high-temperature settings. Catering to industries like offshore oil & gas, petrochemicals, and power plants, Ismail Flanges delivers robust solutions with a commitment to timely delivery, competitive pricing, and customer satisfaction both in Indonesia and around the globe.
Duplex Steel RTJ Flanges are produced using top-notch duplex grades such as UNS S31803 and S32205. Their chemical makeup includes about 22% chromium, 5–6% nickel, and 3% molybdenum, which boosts their corrosion resistance and strength. These flanges boast impressive mechanical properties, featuring a high tensile strength ranging from 620–800 MPa, a minimum yield strength of 450 MPa, and excellent impact toughness, even in low temperatures. Designed for Ring Type Joint sealing, they ensure leak-proof connections in high-pressure pipelines. Their duplex microstructure offers superior resistance to stress corrosion cracking and pitting in harsh, corrosive environments.
