Steam Turbine Components

Precision Profiles has been manufacturing OEM steam turbine components for over 25 years. We specialize in steam turbine vanes (diaphragm nozzles, nozzle blades) for manufacturers such as Siemens, Dresser Rand, Westinghouse, Elliott, Delaval, General Electric, Conmec, Hickham, Worthington, and Murray to name a few.

In addition to steam turbine vanes, we manufacture other components such as:

  • Bucket blades / rotating blades
  • Locking tabs
  • Shroud material
  • Band material
  • Forged rings
  • Spacers
  • Inner Bands
  • Outer Bands

Whether you are building a new turbine or overhauling an existing unit, our team of experts can help you:

  • Reduce component costs,

  • Increase overall production capacity, and

  • Improve turnaround times.

Value-Added Service

Our proprietary process for manufacturing steam turbine vanes (diaphragm nozzles) allows us to produce higher quantities, at a lower cost, and with faster lead times than our competitors – and those MRO shops manufacturing the parts in-house. By partnering with Precision Profiles, you can eliminate the time necessary to machine turbine vanes or other components for your current project – and can re-allocate this time and these resources to final assembly. Depending on what works best for your production process, we offer OEM turbine vanes in two configurations:
