Abstract
One conventional domed slotted rupture disc, which was fabricated with Inconel 600 alloy, was used in reaction kettle. It was burst after only 2000 times of operational circles. The burst causes were investigated. Morphologies of the fracture were observed by scanning electron microscope and the relatively chemical compositions were analyzed by energy dispersive spectrometer. Meanwhile, metallographic microstructures were also observed and analyzed for the material of the failure of the rupture disc. The results show that the bursting of the rupture disc was caused by fatigue fracture.
