Application of magnetic analyzers for detecting carburization of pyrolysis furnace tubes

Abstract: Ethylene pyrolysis furnace is a key equipment in the ethylene production industry with the pyrolysis furnace tube being the core component of the system. The tube operates at high temperature (950°C–1,100°C) and hydrocarbon medium for a long time, and the Cr35Ni45Nb centrifugal casting alloy material is often chosen as the material of the tube. Due to its harsh working conditions, its common failure issues include carburization, high-temperature creep cracking, thermal shock and thermal fatigue, overheating, c… Show more

“…Wang Hui et al [ 8 ] found that there is a process of mutual promotion between carburization and oxidation of the Cr35Ni45 steel furnace tube through the study of its oxidation mechanism in long-term service. Du Chen-yang et al [ 9 , 10 ] studied the detection method of carburization damage of cracking furnace tube based on a magnetic analyzer, ultrasonic guided wave, low-frequency electromagnetism, and other technical means, which provides a new method and means for the practical engineering application of carburization damage of cracking furnace tube. Stamatis A. Sarris [ 11 ] and others studied the effect of oxidation on the coking of furnace tubes and found that the oxide of Cr can play an anti-coking role.…”
