Gas Turbine Reconditioning

• Extended component lifetime – thus optimising turbine life cycle economics.

• Reconditioning solutions cover the full range of gas turbine noble parts.

• Reconditioning parts 40-80% of new parts cost

• Innovative reconditioning technologies to stay ahead of the competition− High temperature braze repair− Laser weld repair− Reopening of cooling holes for complex cooling systems

A typical reconditioning process:
