Shot blasting turbine components.
Shot blasting can be a very efficient alternative to some other cleaning methods.
During a summer stop a turbine was stripped and inspected, the findings that the critical parts were contaminated with scales that can jeopardise the performance of the turbine. We were asked to clean the components including bolts, diaphragms and fan blades to remove the hard deposits, at first the scale was too tough for our media but we upgraded to a recommended media and the job was completed successfully.
Together with our client we learned from the job and put a plan in place to move forward, we can now repeat the job on the next outage to the highest quality and not put the outage timings at risk.
