Ismail Flanges, Jakarta, Indonesia-based, is a trusted Incoloy 825 Flanges manufacturer and supplier offering corrosion-resistant, high-performance flange solutions for harsh chemical and high-temperature applications. Flanges are produced according to international specifications like ASTM B564 and ASME B16.5, providing reliable performance in challenging industries such as chemical processing, offshore oil and gas, pollution control, and nuclear fuel reprocessing. Ismail Flanges’ Incoloy 825 Flanges are renowned for their exceptional strength, dimension precision, and resistance to corrosive materials of a diverse nature.
Incoloy 825 Flanges consist of a majority of nickel content (38–46%), with considerable proportions of iron, chromium, and minute additions of molybdenum, copper, and titanium. This makes them highly resistant to sulfuric and phosphoric acids, seawater, pitting, stress corrosion cracking, and intergranular attack. The tensile strength of these flanges is normally about 585 MPa and is stable in high-hardness conditions at high temperatures, which suits them for both oxidizing and reducing environments.

These flanges are generally applied in heat exchangers, chemical vessels, acid plants, pickling units, and piping systems with aggressive fluids. Incoloy 825 Flanges are especially efficient in systems confronted with aggressive chemicals, high salinity, and temperature stresses. Their superior resistance to localized corrosion and their capability to maintain mechanical properties during long periods of time make them the choice of critical operations demanding safety, reliability, and long-term performance.
