High Temperature Alloy (HTA) Gaskets
The HTA gasket is a single- or multiple-layer, high-temperature alloy substrate capable of sealing at service temperatures up to 1,000° C. Layers contain full or half embossments to provide functions that include localizing contact stress and responding to flange motion. A high-temperature coating is applied for enhanced microsealing and improved abrasion resistance.
Features and benefits include:
- Effective exhaust gas sealing at service temperatures beyond conventional material capabilities (500° C+)
- Mechanical properties of substrate materials maintained at service temperatures up to
1,000° C
- Improved gasket resiliency
- Ability to seal larger flange deflections
- Portfolio of HTA material choices tailored to operating environment conditions
- Installation features can be added (e.g., star holes, bolt holes)
- Low creep relaxation for reduced flange bending and deflection
- Improved bolt-load retention at elevated temperatures
- High Temperature Alloy gaskets optimized for cost and performance
- Delivers Optimized HTA grade for application requirements up to 1000°C
- Up to 5X recovered height improvement (material creep resistance) from 450-1000°C
- Non-oxidizing and thermally stable coating provides 35% –70% reduced coefficient of friction
