A power plant scheduled a month-long shutdown to remove residue and aged surface contaminants from 158m 2 [ 1,700ft 2 ] of stainless steel turbine fans. The turbine’s base would also be refurbished and bearings and seals would be replaced. Plant engineers searched for a way to streamline maintenance and reduce the extra cost of sending the turbine out for cleaning. . With engineering approval, the project contractor used a low dust and low rebound composite abrasive technology called Sponge-Jet Sponge Media abrasive. Silver Sponge Media abrasive with 220-grit and 320-grit aluminum oxide was selected to remove the contaminants and leave the stainless steel substrate unmarred. The contractor noted the following benefits: ¦ Blast-Clean in Sensitive Environments -Sponge Media abrasives dras
