Abstract: Carburization phenomena of the ethylene pyrolysis furnace tube made of 25Cr35NiNb alloy were investigated after service for approximate 30,000 h in a petrochemical plant. Three different zones, namely, oxidation zone, ...

Abstract: Rapid detection technology of the carburization of Fe–Cr–Ni high-temperature heat-resistant alloys in the ethylene cracking furnace and the hydrogen conversion furnace is in great need to prevent industrial accident. This ...
