Home > Incoloy Flanges
Incoloy flanges are top-notch piping components made from nickel–iron–chromium alloys, crafted to perform reliably even in high-temperature and corrosive settings. Renowned for their impressive strength, resistance to oxidation, and thermal stability, these flanges find their place in demanding industrial applications. They’re manufactured to meet international standards, ensuring precise dimensions, secure connections, and a long lifespan. Incoloy flanges shine in environments where heat, pressure, and aggressive chemicals are at play, making them a go-to choice for critical piping systems.
Incoloy alloys mainly consist of nickel, iron, and chromium, with some grades featuring molybdenum, copper, and other elements. This unique blend offers outstanding resistance to oxidation, carburization, and corrosion, even at high temperatures. Incoloy flanges boast impressive tensile and yield strength, excellent toughness, and strong creep resistance. They maintain their mechanical stability across a wide temperature range and perform reliably under high pressure, thermal stress, and challenging operating conditions.
