Westinghouse Utility Steam Turbine Major Inspection

/in , , /by

We recently completed a Major Inspection on a Westinghouse Steam Turbine and Hydrogen-cooled Generator for a Utility in the Southeast U.S.  The project consisted of inspecting the HP/IP Turbine, LP Turbine, and Valves.  The steam path components were blast cleaned and inspected, with minor blade repairs performed on-site.  The turbine rotors had boresonic inspections performed, confirming the good condition of the components.  Bearings T1 – T4 were inspected and found to be in good condition.  The oil deflectors were re-toothed and machined at our qualified repair facility.  The Governor Valves were sent to our valve facility in Gainesville, Georgia where a flexitallic gasket modification was performed.  We performed on-site machining of the steam chest to accept the newly modified gaskets.  The Throttle, Reheat Stop, and Intercept Valves were all inspected at site.  A laser alignment was performed to align steam path components.  Final reassembly was completed, and the unit was turned over to the customer for startup.   This was another excellent project where we finished on-schedule, on-budget, and most importantly – zero safety incidents.  Great work by the PSG team!

We recently completed another “A” Inspection on an Alstom STF Steam Turbine.   This inspection consisted of inspecting the valves, bearings, H2 seals, testing of the generator, an LP crawl through, as well as an HP/IP borescope.  Below is a photo of the T1 Bearing Assembly, in which the bearing was dimensionally inspected and clearances verified to be within OEM design criteria.

We perform A, B, and C inspections on the STF fleet, and many of our team members are former Alstom personnel that have the knowledge required to successfully execute these projects.  Please contact us for all of your STF steam turbine outage planning and execution needs.

Balance Chamber Repair vs. Replace

/in , /by

Save time and money by repairing your balance chamber instead of replacing it.   You no longer need to worry about the hassle of stocking a spare balance chamber, or be surprised by the lead time when you go to order a new one.  We have been repairing balance chambers for utilities across the U.S. for almost 8 years now with great results.   The next time you discuss the future of your balance chamber please contact us to discuss how we can repair your existing component rather than spending the money to purchase a new one.
