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:

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 the reliable service life to 100,000+ hours. This can amount to a maintenance savings of $900,000 - $1,800,000 at the time of engine overhaul.

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