Onsite steam generator repair and maintenance

With Steam Power as your services provider, you will benefit from a wide range of onsite repair solutions that will help reduce maintenance costs and duration and increase the reliability and availability of your generator.

  • APLETEC®: Stator water box leakage repair
    Seal leaking water boxes caused by exposed coating by disconnecting only the hydraulic hoses. Reduce outage duration and cost by avoiding bar removal.
  • Metal spraying: On-site rotor repair
    Sprayed metal repairs steam generator rotor seal oil journals, which reduces friction between the rotor shaft and oil seal rings to reduce the cost of maintenance.
  • On-site stator core repair
    A prosthesis as an alternate technology to partial core ends restacking, which will save several weeks on your outage while reducing your operating costs.
  • On-site stator winding bar re-insulation or replacement
    An alternative repair to full generator rewinds, returning faster to service your generators.
  • CUPROPLEXTM On-site cleaning of stator bars copper hollow conductors 
    Fast, flexible and safe unplugging of hollow conductors by removing copper oxides built up over time. This is an alternative repair to other cleaning methods attacking base copper.

Steam generator workshop repairs

When your maintenance needs go beyond what can be handled on-site, our specialized workshops offer a secure, high-tech environment for heavy-duty repairs.

Repairing your equipment is often a smarter alternative to costly replacements or major upgrades. Whether you are managing an emergency outage or planning for the final years of an asset's life, we help you balance your service spend with your specific operating demands.

We maintain the resources to restore your components to full operation, whether performed at your facility or in our controlled workshop environments:

  • Rotors & blades: Addressing rotor cracks, bowing, or erosion through specialized welding, heat lathing, machining, and leading-edge hardening. 
  • Casings & valves: Re-rounding, balancing, and seal replacements to resolve deformation, leaks, and valve component damage. 
  • Stator windings: Customized solutions for corrosion leaks, insulation failures, and vibration issues, including on-site stripping, re-insulating, or partial rewinds. 
  • Comprehensive systems: Full repair capabilities for compressors, diaphragms, bearings, electrical auxiliary systems, and frames. 

We are well-positioned to deliver repair services where and when you need them, with continuous investment in the development of local resources. With our global presence, we have mastered the logistics needed to maintain reliable supply chains, coordinate resources and comply with regional regulations.
