Turbine Disc Stage 2

Precision-Manufactured Stage 2 Turbine Disc for Gas Turbines, Steam Turbines, and Industrial Power Generation Systems

Product Overview

The Turbine Disc Stage 2 is a critical rotating component located within the second stage of a turbine rotor assembly. It serves as the mounting platform for turbine blades and is responsible for transferring aerodynamic forces generated by the blades into rotational power. As one of the most highly stressed components in a turbine, the Stage 2 Turbine Disc must withstand extreme centrifugal forces, thermal gradients, vibration, and cyclic fatigue throughout its operational life.

Whether used in industrial gas turbines, steam turbines, aero-derivative turbines, marine propulsion systems, or power generation equipment, a precisely manufactured turbine disc is essential for ensuring efficiency, reliability, and operational safety.

At Dawopu, we specialize in the manufacturing of OEM and custom-engineered turbine discs for the global energy, aerospace, marine, and industrial sectors. Using advanced CNC machining, precision forging, and rigorous inspection processes, we produce turbine discs that meet the highest industry standards.

Function of the Stage 2 Turbine Disc

The Stage 2 Turbine Disc performs several critical functions:

• Supports and secures Stage 2 turbine blades
• Transfers blade-generated forces to the turbine shaft
• Maintains rotor structural integrity
• Withstands high rotational speeds
• Absorbs thermal and mechanical stresses
• Contributes to turbine efficiency and power output
• Maintains rotor balance and stability

Because the disc rotates at extremely high RPMs, even minor dimensional deviations can significantly affect turbine performance.
