304 Stainless Steel Crossfire Tubes for Gas Turbines

Product Overview

304 Stainless Steel Crossfire Tubes are combustion-system components used in compatible gas turbines to provide a flame-transfer path between adjacent combustion chambers. During the ignition sequence, crossfire tubes help propagate the flame from an ignited combustor to neighboring combustors, supporting the establishment of combustion throughout the system.

These components must be designed to withstand the thermal environment, pressure conditions, vibration, and operating cycles associated with their specific installation. Accurate dimensions, suitable material properties, and reliable connections are essential for proper fit and dependable service.

Our crossfire tubes are available for gas turbine spare parts and replacement projects based on customer requirements. Manufacturing can be evaluated against original equipment drawings, part numbers, or physical samples to help ensure compatibility with the intended combustion system.

Key Features and Benefits

• Combustion Flame Transfer: Designed to facilitate flame propagation between adjacent combustors in compatible gas turbine systems.

• 304 Stainless Steel Construction: Provides corrosion resistance and general-purpose stainless steel properties, subject to operating temperature and environmental conditions.

• Precision Manufacturing: Tube dimensions, end configurations, and connection details can be manufactured according to approved drawings.

• Replacement Part Supply: Suitable for qualified gas turbine maintenance, repair, and overhaul projects.

• Custom Manufacturing Support: Available for drawing-based or sample-based replacement requirements.

• Quality Inspection: Dimensional checks and material verification can be arranged according to agreed specifications.

Material and Manufacturing

The specified material is AISI 304 stainless steel. Its suitability depends on the actual metal temperature, oxidation exposure, combustion environment, mechanical loading, and original equipment design.

For installations exposed to severe combustion temperatures, the original equipment specification should be reviewed carefully before selecting 304 stainless steel as a replacement material. Other heat-resistant alloys may be required for certain applications.

Manufacturing processes, tube geometry, wall thickness, end connections, surface condition, and dimensional tolerances should follow the approved engineering drawings.

Applications

Crossfire tubes are used in compatible gas turbine combustion systems where interconnected combustors require a flame-transfer passage. They are relevant to maintenance and overhaul projects involving inspection or replacement of worn, cracked, deformed, or otherwise damaged crossfire tubes.

The exact application depends on the turbine model, combustor design, and original part specification.

Custom Gas Turbine Replacement Parts

We support gas turbine spare parts sourcing and replacement manufacturing based on original part numbers, engineering drawings, or physical samples. Technical review can cover material requirements, tube dimensions, wall thickness, connection geometry, and inspection criteria.
