HALO™ Turbine and Compressor Rings

Carbon Graphite Turbine and Compressor Rings

Protect Your Turbines & Compressors with HALO™ Rings for Superior Protection and Performance

We are a globally recognized manufacturer of both OEM and aftermarket carbon graphite turbine & compressor rings. Our HALO rings are preferred by major turbine and compressor manufacturers and are used in a variety of different turbine types, including steam, gas, hydro and wind.

Key Advantages of St. Marys Carbon HALO Rings:

  • Self-LubricatingOur HALO rings are self-lubricating, meaning that a separate lubricant (e.g., oil) is not required, which allows them to be used in both dry-running and sanitary environments.
  • Low Friction / Wear – The self-lubricating properties of our HALO rings will greatly reduce the amount of friction and wear during operation, significantly reducing maintenance time, replacement and equipment damage.
  • High Thermal Conductivity – Our HALO ring materials allow for heat exchange which will prevent overheating and most importantly will not cause damage to your equipment.
  • Stability at High Temperatures – Our proprietary mix of carbon graphite is able to withstand extreme temperatures, which allows our HALO rings to be used in a variety of harsh environments while still maintaining performance and increasing your equipment’s uptime.
  • Anti-Welding/Melting: As our HALO rings can withstand high temperatures, they are resistant to melting or welding to your equipment during operation, allowing your equipment to run longer and perform better.
  • Oxidation-Resistant: Our proprietary mix of carbon graphite resists chemical degradation of the surface material, allowing our HALO rings to be used in harsh environments while maintaining performance.
