Failure Analysis of Weld Cracking in External Cold Water Pipeline of Condenser in Converter Station

Year: 2020

Type: conference-paper

Abstract: The cause of weld cracking in external cold water pipeline of condenser in a ±800kV converter station were analyzed by macro inspection, chemical composition analysis, hardness test, microstructure inspection, scanning electron microscopy and energy spectrum test methods.The results show that the main reason for the cracks is that the material and manufacturing process are not qualified, and the welding process is not good. Corresponding control measures are put forward to avoid similar failures from happening again.
