      • Abstract
    • The cracking behavior of the dome for high efficient desullfurizer unit in a petrochemical power plant was studied.The results showed that part material was not the designed material.The improper material was cracked because of alternate stress in sulfuric-acid environment.The failure forms includes pitting corrosion,intergranular corrosion,stress corrosion and corrosion fatigue.The main failure reasons were corrosion fatigue and delayed fracture.Intergranular corrosion and pitting corrosion were the main reasons of crack initiation.
