Gugsa Flanges, based in the vibrant industrial landscape of Addis Ababa, stands as your reliable local partner for specialized piping components. We take pride in manufacturing and supplying high-performance Incoloy 800, 800H, and 800HT flanges, crafted to meet the rigorous demands of various challenging sectors. Our commitment is to provide Ethiopian industries with top-tier, durable solutions that ensure integrity and longevity in critical applications, supporting the nation’s growth with locally available, world-class quality.
The strength of these flanges comes from their unique composition, a nickel-iron-chromium alloy fortified with titanium and aluminum for stability. This blend delivers outstanding mechanical properties, including exceptional resistance to oxidation and carburization, even under extreme temperatures and pressures. They maintain remarkable creep and rupture strength, making them not just robust, but reliably consistent performers in the most demanding thermal and corrosive environments.

Incoloy 800, 800H and 800HT flanges are used extensively in high-temperature and hot environment applications. Their superior oxidation and carburization resistance makes them best suited for furnace parts, heat exchangers and petrochemical processes. In electrical power generation, these flanges are employed in reheaters and superheaters, where stability at high temperatures is necessary. Furthermore, they find application in chemical and nuclear plants, with equipment being exposed to acid and sulfur environments. Their strength and resistance to thermal stresses guarantee durability in sophisticated applications involving long-term usage.
