Rotor Life Assessment & Extension

The Design Service Life of a gas turbine rotor can be based on statistical predictions of component life, based on an assumed operational mission mix; each rotor component is influenced differently by operational stresses, temperatures, and duty cycles. We look at the Gas Turbine Rotor & Compressor Rotor. A Rotor Life Assessment & Extension service can help decide if component repair, replacement, or use is the best option for your gas turbine rotor to meet operational and maintenance forecasts.

A fin de brindarle las mejores soluciones para su rotor de turbina de gas, MD&A determina sus necesidades específicas además de evaluar las inspecciones del rotor:
