Liburdi's Advanced Repairs for expensive critical turbine components:

• Buckets,
• Nozzles,
• Shroud Blocks,
• Combustor Liners,
• Transition Pieces,
• Fuel Nozzles.

Component Life Extension — savings for the operator:

The conventional repairs carried out by others are limited to weld repairs and strip/recoat. The parts are then typically retired after 50,000 - 70,000 hours of service per OEM convention. Liburdi's Advanced Repairs are designed and proven to extend reliable service life to 100,000+ hours.

This can amount to a maintenance savings of $1,000,000 - $2,000,000 at time of engine overhaul.

Savings = the difference between the cost of new parts and the cost of the Advanced Repairs.
