Siemens Turbine Repair

Project Summary

Contracted by the DR/Siemens Turbine Repair team to perform a High Velocity Oil Flush (HVOF) on the Unit #1 Westinghouse 501AA located in West Phoenix. A previous contractor was unsuccessful in achieving adequate flows to flush the turbine.

A Variable Frequency Drive was utilized on the 2000 GPM flushing skid, with technicians checking for leaks as they started the circulation system slowly. Target temperature for the 36-hour course flush was between 120-160 degrees Fahrenheit. The process successfully removed any foreign materials from the system.
