Operating temperatures of pyrolysis furnaces are sometimes in excess of 2000/sup 0/F (1100/sup 0/C). These temperatures are very detrimental to the life of the typical HK-40 furnace tubes which normally have a three to five year life in the hot section of these furnaces. Short life is attributed to rapid carburization of ID surfaces which subjects tubes to higher than normal stresses and results in creep cracking of furnace tubes. As an aid to understanding the materials problems the ethylene process will be presented, along with data on the carburization of furnace tubes.
