Non-Asbestos Fiber Gasket

Non-Asbestos Fiber Gasket Overview

Chunhuan non-asbestos fiber gaskets provide a safe, eco-friendly replacement for traditional asbestos gaskets in demanding flange and valve sealing applications. Made from aramid, carbon, and glass fibers blended with polymers like NBR or FKM, these gaskets deliver superior mechanical strength, chemical resistance, and thermal stability, making them ideal for petrochemical, power, marine, machinery, and food industry pipelines.

Available in economic, standard, chemical-resistant, and high-pressure grades, the gaskets meet international standards such as ASME, DIN, and JIS, and are suitable for high-temperature and high-pressure conditions.

Key Features and Advantages

100% Safe & Eco-Friendly

• Completely asbestos-free, eliminating occupational health risks (e.g., asbestosis, mesothelioma).

• Environmentally friendly manufacturing and disposal, supporting sustainable operations.

Exceptional Sealing Performance

• Excellent Resilience & Compensation: Fiber structure and elastic binders ensure long-term sealing by compensating for flange irregularities, thermal creep, and bolt stress relaxation.

• Wide Chemical Compatibility: Resistant to water, steam, oils, fuels, acids, alkalis, solvents, and hydrocarbons.

• Anti Blow-Out Capability: High mechanical strength and flexibility prevent gasket extrusion under pressure fluctuations.

Mechanical & Thermal Performance

• High Strength & Pressure Resistance: Uniform fiber distribution and high-pressure molding allow reliable performance in high-pressure flange connections.

• Wide Temperature Range: Stable performance from –100°C to +500°C depending on material formulation.

• Low Creep & Relaxation: Maintains initial bolt stress longer than conventional gaskets, reducing maintenance.

Convenience & Cost-Effectiveness

• Easy to cut and install, suitable for complex flange shapes.

• Competitive pricing with long service life, offering lower total lifecycle cost.

Core Applications

• Petroleum, Gas & Refining: Flanges, valves, pumps, reactors, heat exchangers; suitable for crude oil, refined fuels, natural gas, and catalytic cracking units.

• Chemical & Pharmaceutical: Sealing corrosive chemical production, storage, and process pipelines.

• Power & Energy: Steam, feedwater, and auxiliary pipelines in thermal, nuclear, and biomass plants.

• Marine & Shipbuilding: Engine, fuel, lubrication, and seawater cooling systems.

• Machinery & Industrial Equipment: Hydraulic, compressed air, and cooling circuits, and other industrial flange connections.

• Food & Beverage: Steam, hot water, and harmless media pipelines meeting hygiene standards (with suitable formulations).

Conclusion

Chunhuan non-asbestos fiber gaskets offer a perfect balance of safety, mechanical strength, chemical resistance, and thermal stability. Their excellent resilience, wide temperature range, and anti-creep properties ensure reliable, long-lasting flange sealing in diverse industrial applications. With customizable grades, formulations, and surface treatments, these gaskets provide a high-performance, eco-friendly, and cost-effective sealing solution.
