Effect of Compressed Natural Gas (CNG) on corrosion behaviour of brass valve of CNG cylinder
In this case study, failure root cause analysis of the Compressed Natural Gas (CNG) cylinder
brass valve was investigated. Detailed metallurgical analysis of the cracked CNG valve was
performed. Higher content of sulphur and carbon while depletion of zinc observed by
Scanning Electron Microscope (SEM)-Energy Dispersive Spectroscopy (EDS) analysis at
crack location and on black corrosion product. Microstructure analysis of the cross section
near to fracture surface indicated dendritic structure of alpha and beta phase and depletion …
