Turbomachinery Repair Services & Component Manufacturing for Power Generation
For over 70 years, HFW Industries has been a trusted partner to the power generation industry. Whether you’re a public utility, an OEM for power-related machinery, a company powerhouse or a renewable energy provider, 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. HFW can hold tolerances as tight as 0.0002”.
Our one-source service model—machining, thermal spraying, hardfacing, precision grinding, and assembly in one facility—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.

Turnkey Capabilities for Power Generation Equipment Repair
- Full Component Manufacturing & Repair – From supplying raw materials to completing final inspection
- Advanced Thermal Spray Coatings – Tungsten carbide, chrome carbide, plasma spray, stainless steel, custom blends
- Metallurgical Hardfacing Weld Overlays – PTA, Arc, TIG, MIG for heavy wear and severe impact resistance
- Precision Grinding & Industrial Finishing – Cylindrical, ID, and surface grinding directly to 0.0002” tolerances
- Mechanical Assembly & Inspection – Complete rebuilds, EMRO checks, and final assembly to OEM specs or better
For example, if you're working with a turbine shaft:
We can supply material, machine the part complete, apply engineered 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 an industrial shaft or bearing 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.
Typical Rotating Equipment Components We Manufacture or Restore
The following is a non-exhaustive list of typical industrial power generation applications:
- Turbine & Turbocompressor Shafts
- Inlet Pipes
- Seal and Bearing Housings
- Rotor Components & Journals
- Pistons and Piston Rods
- Seals
- Valve Seats and Discs
- Valves and Valve Stems
- Bushings and Couplings
- Gear Box Bore Repair
Mitigating the $1.5 Trillion Industrial Downtime Risk
A 2023 Siemens report revealed that unanticipated asset downtime costs global industrial companies an estimated $1.5 trillion annually—accounting for roughly 11% of their total revenue. For power generation professionals, the root cause of these failures often stems from microscopic quality oversights, micro-cracking, or undetected shaft vibrations.
At HFW Industries, we fight this revenue leak with an intense culture of shop-floor discipline. We are proud to be ISO 9001:2015 certified. Our Quality Management System (QMS) ensures repeatability and traceability across every phase of production.
We manage your component’s entire lifecycle under one roof—machining, automated HVOF spraying, and precision cylindrical grinding down to 0.0002 inches. Every high-speed asset is temperature-normalized inside our climate-controlled inspection cells before receiving final measurement. Using over 800 instruments independently calibrated to NIST 2540-1 and ISO-10012 standards, alongside comprehensive Electrical Mechanical Runout (EMRO) and TIR checks, we mitigate catastrophic vibration risks before your turbine shafts, rotors, and journals return to service.
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 our engineering team typically matches a coating to your application environment:
- Tungsten Carbide (HVOF) – Best for severe wear and abrasion protection in applications under 1000°F.
- Chrome Carbide (HVOF) – Used above 1000°F or when simultaneous corrosion and sliding wear resistance is critical.
- Stainless Steel or Custom Blends – Used for structural buildup, base dimension restoration, or when unique customer specifications dictate.
Each engineered surface coating is selected to extend surface life, improve resistance to severe abrasion, particle erosion, and corrosion, and reduce your plant's maintenance cycles.
Why Power Gen Reliability Engineers Choose HFW
- Proven Turbomachinery Expertise – Decades serving reliability engineers and plant managers
- Emergency Outage Response – Short lead times and rapid quoting when downtime costs are high
- One-Source Efficiency – Fewer vendors, faster turnaround, and simplified procurement
- ISO 9001:2015 Certified – Every job is inspected and signed off at every stage of production
