Turbine components though resilient are exposed to extreme operating conditions, such as high temperatures, corrosive environments, and physical damages.
APG’s on-site component coating services reduce outage time and damage risks when shipping large industrial components to an off-site facility. We use high-temperature oxidation and corrosion coatings that help the components withstand high temperatures and other extreme chemical attacks while increasing the turbine's efficiency.
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.
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.
For more than 10 years, APG has extended its expertise in repairing hot gas path and combustion components for the Alstom gas turbine fleet. From ALSTOM GT11 compressor repairs to ALSTOM GT11 vane carrier repairs, and beyond. Currently, we are providing comprehensive repairs and rehauling for GT11 D4, D5, and N1 gas turbine models in the power generation, oil & gas and industrial markets.
Throughout our history, we have developed solutions to improve IGT reliability and availability with 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. We use noble metal thermocouples (available in Type B, R, and S) which can withstand extreme temperatures without affecting the results. The highly accurate and stable results make noble metal thermocouples better than base metal thermocouples for generating sustainable power for years.
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. The modifications include upgrading the materials used for manufacturing parts for high resilience against extreme temperatures, corrosion, etc., redesigning the turbine blades to improve airflow or accommodating evolving requirements of the output power. The ultimate aim is to redesign parts so as to extend the life of the equipment and improve its overall performance. Thus improving the reliability and availability of gas turbines.
APG is committed to maximising the availability, reliability and efficiency of industrial gas turbines for sustainable power generation.
