GE Gas Turbine Crossfire Tube 306A4456G001

The 306A4456G001 Crossfire Tube is a critical combustion system component used in GE Frame 5 (MS5001) industrial gas turbines. Multiple turbine spare parts catalogs identify 306A4456G001 as a Crossfire Tube (X-Fire Tube) for GE Frame 5 gas turbine combustion systems.

A crossfire tube connects adjacent combustion chambers and allows flame propagation during the ignition sequence. When the igniter initiates combustion in one combustor, the flame travels through the crossfire tubes to ignite neighboring combustion chambers, ensuring reliable turbine startup and stable combustion.

Because the crossfire tube operates directly within the combustion section, it must withstand:

• Extreme temperatures
• Thermal cycling
• Combustion vibration
• Oxidation
• Pressure fluctuations

At Dawopu, we manufacture OEM-quality gas turbine combustion components using high-temperature nickel alloys and precision aerospace manufacturing processes.
