Processes for component repair

We have been repairing gas turbine components since 1990. Our dedicated, 40,000 sq ft component repair facilities are equipped with the latest technologies. We offer a comprehensive range of repair solutions to protect components against wear and corrosion, increasing part life and reducing the cost of ownership of your equipment.

We support all of your critical parts, including turbine blades, nozzle guide vanes and stator vanes, seal segments, rotor blades, casings, bearings, turbine discs, shafts and couplings, and combustion hardware.
