Radiant coils of cracking furnace

In the steam cracking furnaces of the petrochemical industry, cracking furnace tubes and bend castings are required to withstand external temperatures approaching 1100°C, while simultaneously resisting internal carburization corrosion caused by hydrocarbon gases and external high-temperature oxidation. Consequently, the materials used must demonstrate exceptional corrosion resistance and creep resistance under these extreme high-temperature operating conditions.
