On-site inspection of Renk TB-800 turbo gearbox

In-depth diagnostic inspection of a 25.5 MW Renk turbo gearbox in Estonia, utilizing advanced NDT methods to verify component integrity.

We performed a rigorous on-site inspection of a Renk TB-800 turbo gearbox located in Estonia. This high-performance unit, rated at 25,550 kW with input speeds exceeding 6,700 rpm, is a critical component of the local power generation infrastructure.

To ensure a comprehensive assessment of the gearbox's health, our specialists went beyond simple visual checks. We employed advanced diagnostic methods, including magnetic particle inspection (MPI) to detect microscopic surface defects and contact pattern testing with marking compound to verify precise gear alignment. This multi-layered approach allowed us to provide the client with a definitive report on the unit's condition and reliability.
