Despite the recent efforts to define the effects of deposits on corrosion of steel surfaces and their […]

Electronic inspection – Using mobile devices to manage assets and inspect corrosion

[vc_row][vc_column][vc_acf field_group=”3279″ field_from_3279=”field_5b7cf545d605d” show_label=”yes” el_class=” “][vc_acf field_group=”3279″ field_from_3279=”field_5b7cf51dd605c” show_label=”yes”][vc_acf field_group=”3279″ field_from_3279=”field_5b7cf568d605e” show_label=”yes”][/vc_column][/vc_row][vc_row][vc_column][vc_column_text] Abstract Asset management and many corrosion inspection activities are currently performed using paper-based inspection methods. The rise of smartphone and tablet technology has now enabled these crucial operations to be undertaken electronically. Paper-based methods are consistently proving outdated and cumbersome when compared to […]
