AS FR-SPG-C
Carbon spiral groove face ring for dry gas seals. Lightweight carbon construction with precision-machined spiral grooves for optimal gas film generation.
Technical Specifications
- Material: Resin-impregnated Carbon
- Groove Pattern: Logarithmic spiral
- Surface Finish: Ra ≤0.2 μm on sealing face
- Flatness: ≤0.9 μm (2 light bands)
- Applicable Pressure: Up to 10 MPa
- Applicable Speed: Up to 100 m/s linear velocity
Design Features
- Carbon's self-lubricating properties provide inherent dry-running capability during transient start-up and shutdown phases.
- Low coefficient of friction minimizes heat generation during momentary face contact events.
- Excellent thermal shock resistance — tolerates rapid temperature changes without cracking.
- Typically used as the stationary (mating) face ring paired with SSiC or TC rotating rings.
