AS FR-SPG-TC
Tungsten Carbide spiral groove face ring for dry gas seals. Superior hardness and wear resistance with precision spiral grooves for demanding high-pressure applications.
Technical Specifications
- Material: Tungsten Carbide (TC)
- Groove Pattern: Logarithmic spiral
- Surface Finish: Ra ≤0.1 μm on sealing face
- Flatness: ≤0.9 μm (2 light bands)
- Applicable Pressure: Up to 18 MPa
- Applicable Speed: Up to 150 m/s linear velocity
Design Features
- Tungsten Carbide provides the highest hardness (HRA ≥90) and wear resistance among DGS face ring materials — ideal for abrasive or high-pressure gas streams.
- Spiral groove pattern precision-machined to tight tolerances for consistent gas film stiffness and optimal stiffness-to-leakage ratio.
- Superior thermal conductivity dissipates frictional heat during transient contact events.
- Preferred material for high-pressure compressor DGS applications exceeding 10 MPa.
