Vane Pinning: Robust, low-cost repair for square based compressor stator vanes on Gas Turbines.

PREVENT

Loose stator vanes and protruding shims can heighten aerodynamic stimuli that increase deterioration which can lead to catastrophic damage.

Unplanned Outage

REPAIR

CTTS's patented solution locks vanes into a robust ring segment that reduces the wear and tear that leads to costly compressor failure. 

 

Planned Outage

PERFORM

The calculated performance can be as much as 0.3% which on a 7FA base loaded gas turbine can save over $100k/year in fuel cost in addition to reduced emissions. 

Increase Efficiency

OUR SERVICES

The repair can be accomplished during and outage with the upper casing removed and in many cases with the rotor in place.  The repairs can be done within a typical outage via removal of effected vanes that are then drilled and pinned.  With hundreds of gas turbines modified to date, there is no doubt that the process is proven, reliable and much less costly than other solutions.
