Replacement Bellows and Expansion Joints in Gas Turbine Repairs Fuel Nozzle Bellows Gas turbines, such as GE’s 7FA, have bellows in the fuel nozzles. It is recommended that these bellows be replaced during major turbine over-hauls.

Reverse engineered fuel nozzle bellows Expansion Ring Replacement bellows for hard to find parts such as this expansion ring that came off of a Westinghouse turbine.

New and rebuilt services for leaking parts Cross-Fire Bellows GE 7FA users found that the original graphite slip joints in the cross-fire tubes leaked, which increased temperatures in the turbine casing.

The upgrade to the graphite packed joint is a flanged alloy bellows expansion joint, which has proven to be a successful upgrade.
