INVESTIGATION ON THE EFFECTIVENESS OF NITROGEN GAS FOR SURFACE NITRIDING OF INTERNAL PIPE SURFACE EROSION

This report presents an investigation on the effectiveness of nitrogen gas for surface nitriding of internal pipe erosion. Erosion in piping system always cause problems in oil and gas production facilities. Most of the issues happen due to difficulties in monitoring the condition of the internal co...
