Coatings
A comprehensive review of the coating on your unit may reveal opportunities to gain unit reliability. These gains can be in the increased repairability of the parts, extended parts life and increased outage intervals.
- Rotors corrosion coating and anti-rock coatings can extend the life of the parts.
- Combustion systems coating can be applied to reduce wear due to high temp., reduce oxidation and reduce the impact of interface wear.
- Turbine section coatings typically allow for the reduction of surface metal temperatures and the impact of oxidation on the parts.
Compressor
Our extensive experience on custom solutions, modifications and repairs allows us to support all applicable OEM technical recommendations on 7FA, 7EA and Siemens/Westinghouse frame compressors. We specialize in repairing compressor issues involving clashing, stator shim elimination, case slippage, stator vane rock, blade tip rock, spacer migration, R17 replacement, and a complete line of compressor rotor shop support. We also have a robust shim elimination program. We can supply and install our own shrouded S17 that is an upgrade to the OEM supplied solution.
Instrumentation Upgrades
There are many opportunities on older frame units to increase reliability with instrumentation upgrades to a unit. This can include bearing metal thermocouple, vibration systems and thermocouple upgrades to allow for replacement without disassembly, flux probes to bus couplers including changes from switches and gauges to transmitters to name a few.
Parts modifications
During the repair cycle, there are a number of modifications we offer to increase the reliability of the unit. With unparalleled expertise, we specialize in transition piece, cap and liner assemblies for Frame 6B, 7B, 7E/EA, 7FA +EL, and 9E GE Gas Turbines.
