CARBON GRAPHITE TURBINE AND COMPRESSOR RINGS MANUFACTURING

St. Marys Carbon manufactures HALOTM turbine & compressor rings from superior carbon graphite grades, including carbon graphite, electrographite and resin-bonded graphite for a variety of applications. St.Marys Carbon is widely recognized in this industry and is the preferred supplier for many major manufacturers.

All of our turbine & compressor rings, from the blending of raw materials to the finished product, are made inhouse by our specialized craftsmen.

Our HALO rings can be custom-manufactured to your specific requirements. We develop our own proprietary grades and manufacture each product in-house, so we will work closely with you to create a product that is right for you.

ENVIRONMENT, OPERATING CONDITIONS & APPLICATIONS

Dry running Oil Less

DRY-RUNNING / OIL-LESS

Greatly reduces failure rates and allows for use in sanitary environments due to its self-lubricating properties.

High Temperature Stability

HIGH TEMPERATURE STABILITY

Maintains high strength and runs effectively without failure at high temperatures.

High Thermal

HIGH THERMAL CONDUCTIVITY

Allows for heat exchange to prevent overheating.

Low Friction Wear

LOW FRICTION / WEAR

Resists wear and reduces friction as it is chemically inert, oxidation-resistant and self-lubricating.

Mechanical Seal

Carbon Graphite Mechanical Seal Types

Rotating equipment often requires a dynamic mechanical seal to create a seal between a rotating shaft and a stationary body and prevent the escape of process fluid(s) including liquid and/or gas. They can also be used in mixer seals to prevent fugitive ambient particulates from entering a contained vessel being being mixed such as a pharmaceutical reaction…

Bearing Life

Why Bearings Fail and How to Prevent It

All bearings have a fixed life expectancy. Some are replaced because of normal wear or spalling, and others need replacing because of premature wear or failure. An unexpected failure can cause damage to equipment, downtime, costly replacement, and possibly even injury. And, even before they fail, the premature wear is likely to have effects on performance …

Graphite Conductivity

Carbon Graphite Conductivity & Expansion

When deciding on the materials for carbon graphite components or parts, it all starts with a thorough review of the application which includes the components’ form/function/fit and property identifying the “must haves” and the “nice to haves” and melding these with a design for manufacturability. There are three important physical characteristics …
