Abstract:

Article Preview

In order to find out the accident urea reactor explosion reasons, based on the accident investigation, the reactor structure was anatomyed, the macroscopic and microscopic fractures were sampled and observed, The results show that the trace sodium, potassium and other alkaline ions content in the liquid of liquefied steam is the stress corrosion medium reason; the leak detection pine and the 16MnR laminate connecting with screw joint is the structural reasons; typical stress corrosion had occurred on the accident urea reactor cylindrical segment base metal and welding. Some important suggestions were given
