Product Description
Custom Steam Turbine Rotor Wheel (Turbine Disk)
Product Overview
The turbine rotor wheel (turbine disk) is a core rotating component of steam turbines. Turbine blades are mounted on the wheel rim. During operation, it bears huge centrifugal force, alternating thermal stress, steam impact and vibration loads, directly determining the safety, efficiency and service life of the whole unit.
We provide full customized manufacturing services for turbine disks suitable for large thermal power turbines, medium & small industrial turbines, waste heat turbines, back-pressure turbines and condensing turbines. Products include integral forged turbine wheels and welded composite disks. We strictly manufacture according to customer drawings and power industry standards, supporting new unit assembly and overhaul spare part replacement. Stellite hardfacing service is available for partial working surfaces on demand.
Main Product Types
- Integrally forged turbine disk (Primary choice for high/medium pressure stages, high structural reliability)
- Split-type rotor wheel
- Welded composite turbine disk
- Retrofit optimized disk for efficiency upgrade of existing units
Available Forging Materials
30Cr2Ni4MoV, 25Cr2MoV, 42CrMo, 34CrNiMo6 and other high-strength rotor dedicated alloy steels. Material selection matches operating temperature, rotating speed and pressure parameters of different turbine stages.
