Carbon & Graphite Packing | Steam Valve & Pump Packing

Kaybin supplies carbon and graphite gland packing for high-temperature steam valves and pumps operating in power generation, petrochemical and heavy industrial environments across South Africa and Africa. Combining expanded graphite sealing performance with carbon reinforcement where greater structural strength is required, these packings are selected to improve leakage control, resist extrusion and support reliable service in demanding steam applications.

Material & Duty

Carbon and graphite packing is primarily used in steam-duty valves and pumps where temperature, pressure and thermal cycling make general-purpose packing unsuitable. Graphite provides conformability and thermal stability, while carbon reinforcement improves structural integrity in more demanding operating conditions.

Typical Applications

• High-temperature steam valve stems
• Boiler feed pumps
• Refinery and petrochemical process valves
• Power station auxiliary systems
• Heavy industrial steam lines

Performance Considerations

Performance depends on the application, motion type and installation condition. Valve service and rotary pump service must be assessed differently, with factors such as pressure, shaft speed, sleeve condition, gland load and extrusion gap all affecting packing life and sealing reliability.

Common Service Issues Addressed

• Steam leakage
• Extrusion under pressure
• Blowout risk during cycling
• Shaft or sleeve scoring
• Thermal degradation in severe steam duty

Supply

Available in various metric sizes and supplied by the box or per kilogram.

Selection Requirements

Correct specification is based on:

• Shaft diameter
• Stuffing box dimensions
• Operating pressure
• Operating temperature
• Shaft speed
• Steam condition
• Sleeve or stem condition
