Abstract
In this paper, the problems of short service life, main failure modes and failure mechanisms of ethylene pyrolysis furnace tubes in China were summed up through service condition survey on ethylene pyrolysis furnace tubes in the domestic nine petrochemical corporations, compared with the situation of two ethylene enterprises in the developed countries. Chemical composition, tensile properties at room temperature and high-temperature stress rupture properties of furnace tubes and fittings were obtained through experiments performed on furnace tubes and fittings from six furnace tube manufacturing enterprises. The revision suggestion of centrifugally cast alloy tubes standard and the relationship between newly manufactured furnace tubes and fittings performance and serviced furnace tube failure modes were also discussed in present article.
