6003T32P26 Combustion Liner

Overview

The 6003T32P26 Combustion Liner is a key component within the combustion chamber of gas turbine engines. It plays a crucial role in maintaining stable combustion, protecting surrounding structures from extreme heat, and ensuring efficient fuel burning within the turbine system.

During turbine operation, the combustion liner is exposed to extremely high temperatures, intense pressure fluctuations, and aggressive combustion gases. Therefore, it must be manufactured from high-performance heat-resistant materials and designed with precision to maintain durability and operational stability.

HGTP specializes in the precision manufacturing and machining of high-temperature turbine components, including combustion liners, turbine housings, and other complex aerospace and energy industry parts. With advanced CNC machining capabilities and strict quality control systems, HGTP delivers high-reliability components designed for demanding turbine environments.

Function of the Combustion Liner

The combustion liner forms the inner wall of the turbine combustion chamber. Its primary purpose is to contain and guide the combustion process while protecting the outer casing of the engine from direct exposure to high-temperature flames.

Key functions include:

• Containing the combustion flame within the chamber

• Directing airflow and fuel mixture for stable combustion

• Protecting turbine structural components from extreme heat

• Supporting efficient fuel combustion and energy generation

Proper design and manufacturing of the combustion liner help improve fuel efficiency, combustion stability, and turbine reliability.

Materials Used in Combustion Liners

Because combustion liners operate under temperatures that may exceed 900°C – 1200°C, advanced high-temperature materials are required to maintain structural strength and oxidation resistance.

Nickel-Based Superalloys

Nickel-based superalloys are commonly used in combustion liners due to their exceptional high-temperature performance.

Typical alloys include:

• Inconel 718

• Inconel 625

• Hastelloy X

These materials offer:

• Outstanding heat resistance

• High mechanical strength at elevated temperatures

• Excellent oxidation and corrosion resistance

Such properties make them ideal for long-term operation in turbine combustion systems.

Heat-Resistant Stainless Steels

In some turbine designs, high-temperature stainless steels such as AISI 321 or AISI 347 may be used.

These alloys provide:

• Good thermal stability

• Resistance to oxidation

• Structural reliability under repeated thermal cycles

Manufacturing Process

Producing a combustion liner requires specialized manufacturing techniques due to the complex geometry and demanding material properties.

HGTP utilizes advanced production technologies to ensure the precision and durability of turbine components.

Precision CNC Machining

After the initial forming process, CNC machining is used to achieve the final dimensional accuracy required for turbine assembly.

HGTP uses multi-axis CNC machining centers capable of machining complex geometries with tight tolerances.

Machined features include:

• mounting flanges

• cooling holes

• interface surfaces

• attachment structures

Precision machining ensures correct alignment and proper integration with the combustion chamber assembly.

Sheet Metal Forming and Fabrication

Many combustion liners are produced using advanced sheet metal forming processes, including rolling, deep drawing, and precision welding.

These techniques allow manufacturers to produce lightweight structures while maintaining the strength needed to withstand combustion pressure.

Laser Drilling and Cooling Hole Machining

Combustion liners often contain hundreds of small cooling holes designed to provide film cooling. These holes allow a thin layer of air to protect the liner surface from direct flame exposure.

Typical cooling hole diameter:

0.5 mm – 2 mm

Laser drilling or electrical discharge machining (EDM) is commonly used to create these precision cooling features.

Technical Specifications

Although the exact specifications for the 6003T32P26 Combustion Liner depend on the specific turbine design, typical technical parameters may include:

Outer diameter
200 mm – 600 mm

Wall thickness
1.5 mm – 6 mm

Operating temperature range
900°C – 1200°C

Tolerance for critical features
±0.02 mm – ±0.05 mm

Cooling hole diameter
0.5 mm – 2 mm

Surface roughness
Ra 0.8 – 1.6 μm

These specifications ensure that the liner maintains structural integrity while operating under extreme thermal conditions.

Inspection and Quality Assurance

Due to the critical role of combustion liners in turbine safety and performance, strict inspection and testing procedures are required.

HGTP implements comprehensive quality control measures during production.

Dimensional Inspection

High-precision measuring equipment such as Coordinate Measuring Machines (CMM) is used to verify all critical dimensions.

Non-Destructive Testing

Non-destructive testing methods are used to detect internal defects without damaging the component.

Common methods include:

• dye penetrant inspection

• ultrasonic testing

• radiographic testing

These inspections ensure that the combustion liner is free from cracks, porosity, or structural weaknesses.

Material Verification

Material composition and heat treatment results are verified to ensure compliance with turbine material standards.

Typical tests include:

• hardness testing

• metallographic analysis

• chemical composition analysis
