Themba Nickel Alloys in Cape Town, Cape Town, is a reliable manufacturer and exporter of Incoloy 800, 800H, and 800HT flanges. With their high precision engineering and superior quality, the flanges are capable of performing well under high temperatures as well as high corrosive environments. Themba Nickel Alloys provides products up to international standards, catering to markets in petrochemical, power generation, and heat treatment industries. With a heavy emphasis on performance and durability, the company supplies Incoloy flanges that provide secure and safe piping connections for high-performance critical systems under thermal and mechanical stress.
Incoloy 800, 800H, and 800HT flanges are constructed from a nickel-iron-chromium alloy with controlled levels of carbon, aluminum, and titanium added. Such alloys have been formulated to withstand oxidation, carburization, and sulfidation at high temperatures. Incoloy 800 offers good corrosion resistance and strength, whereas 800H and 800HT offer enhanced creep and stress rupture properties because they contain more carbon and undergo special heat treatment. These flanges have mechanical stability up to 1100°C and do not deform under thermal stress. Their superior metallurgical structure avoids intergranular corrosion and stress-corrosion cracking, enabling them to be used in challenging applications over extended periods of time.

Incoloy 800, 800H, and 800HT flanges find extensive application in industries demanding high strength and resistance to heat. They are generally mounted in piping systems for heat exchangers, reactors, superheaters, and furnace parts in chemical and petrochemical plants. In power generation, the flanges find application in boiler headers and nuclear steam systems due to high operating temperature stability. The oil and gas industry also depends upon these flanges to function in high-temperature, high-pressure applications. Due to their corrosion resistance and durability, they are the most suitable for long-term operation at severe chemical and thermal conditions.
