Experience in maintenance and repair services for Gas Turbine hot gas path parts

Throughout the years, ATLA has accumulated experience, which translates into excellent quality services.

Our facilities in Chieri focus on the repair of Gas Turbine hot gas path parts, such as blades and vanes, for power generation and aircraft industry both. The gas turbine may have a simple operating principle, but the equipment comprises of highly specialized components.

We can quickly and cost effectively provide comprehensive technologies and repair solutions to ensure the best possible services to our Customers.

Over 500.000 parts stripped, repaired and coated

Maintenance is fundamental to ensure optimum performances.

By our Facilities we can repair rotor and stator blades and other hot parts of the gas turbine and deliver these parts “as new” relying on our long experience.

Preliminary Inspection and Testing

We offer a range of Non Destructive and Destructive Testing services. Carrying out testing tasks is fundamental in order to make sure quality and safety standards are met.

Each inspection process provides a detailed list of the features of the detected defects, determining whether or not the part is fit for a desired function. During the whole manufacturing process, starting from the raw material, all individual parts are monitored and inspected by our Quality Department.
