Power Gen & Turbomachinery Repair: One-Source, Precision Services

For over 70 years, HFW Industries has been a trusted partner to the power generation industry. Whether you’re a public utility, OEM for power-related machinery, a company powerhouse or in renewable energy, equipment reliability is critical.  We manufacture, repair, and restore critical turbomachinery components such as turbine shafts, rotors, seal housings, bearing housings, and balance pistons with OEM-level precision.

Our one-source service model—machining, thermal spraying, hardfacing, precision grinding, and assembly under one roof—means faster lead times, lower costs, and consistent quality control. Whether you’re facing wear, erosion, corrosion, or dimensional loss, HFW delivers cost-effective solutions that extend service life and keep your operation online.

Capabilities for Power Generation

  • Full Component Manufacturing & Repair – From raw material supply to final inspection
  • Thermal Spray Coatings – tungsten carbide, chrome carbide, plasma spray, stainless steel, custom blends
  • Hardfacing Weld Overlays – PTA, Arc, TIG, MIG for heavy wear and corrosion resistance
  • Precision Grinding & Finishing – Cylindrical, ID, and surface grinding to 0.0002” tolerances
  • Assembly & Inspection – Complete rebuilds, EMRO checks, and final assembly to OEM or better

For example, if you're working with a turbine shaft:

  • We can supply material, machine the part complete, apply thermal spray coatings (for wear, corrosion, or high-temp resistance), grind it to tolerance, and inspect it using electrical mechanical runout (EMRO) and TIR checks down to .0002".

If you're repairing a shaft or housing:

  • We can rebuild worn diameters, apply high velocity oxy-fuel (HVOF) coatings (like tungsten carbide or chrome carbide), and return the part to OEM specifications—or better.

Typical Components We Manufacture or Restore

The following is a non-exhaustive list of typical applications:

  • Component Reconditioning
  • Shafts – Turbine, Turbocompressor (and more)
  • Inlet Pipes
  • Seal and Bearing Housings
  • Rotor Components
  • Pistons and Piston Rods
  • Seals
  • Valve Seats and Discs
  • Valves and Valve Stems
  • Bushings and Couplings
  • Gear Box Bore Repair

Thermal Spray Coatings for Turbomachinery

Thermal spray coatings are at the heart of our repair and wear-prevention strategy. We use high velocity oxy-fuel (HVOF), plasma spray, and hardfacing processes depending on application needs.

Here’s how we typically choose a coating:

  • Tungsten Carbide (HVOF) – best for wear protection in applications under 1000°F
  • Chrome Carbide (HVOF) – used above 1000°F or when corrosion + wear resistance is critical
  • Stainless steel or custom blends – used for buildup, dimension restoration, or when customer spec dictates

Each coating is selected to extend surface life, improve resistance to abrasion, erosion, and corrosion, and reduce maintenance cycles.

Why Power Gen Customers Choose HFW

  • Proven Turbomachinery Expertise – Decades serving reliability engineers and plant managers
  • Emergency Response – Short lead times and rapid quoting when downtime costs are high
  • One-Source Efficiency – Fewer vendors, faster turnaround, simplified procurement
  • ISO 9001:2015 Certified – Every job is inspected and signed off at every stage
