Team was mobilized to the Afrisam Ulco plant to conduct NDT inspections to their Electrostatic Precipitator (EP). The result of the NDT tests were then provided to the client who indicated critical areas where additional plating needed to be installed to ensure the longevity of the vessel structure.
NDT process used was UTM (Ultrasonic Thickness Measurements). This process allows the user to identify the current thickness of steel and measuring against the original designed thickness, a decision could be made whether the structure requires new plate.
For welding works, teams were using normal stick welding process. With some of the welding being performed on ropes, it was more practical to use this process due to it’s compact requirements and ease of mobility.
Scope of works included:
Performing NDT (UTM) inspections on EP vessel and compiling reports for client.
