Арамидная прокладка без асбеста

Non-Asbestos Aramid Gasket Overview

Our non-asbestos aramid gaskets are engineered to replace traditional asbestos gaskets in high-temperature, high-pressure flange applications. Constructed from high-strength aramid fibers (e.g., Kevlar) combined with polymers such as NBR or FKM, these gaskets provide superior mechanical strength, chemical resistance, and thermal stability while being environmentally safe.

Designed to meet international standards such as API 607 and EN 1514-1, these gaskets are suitable for petrochemical, power, pharmaceutical, and high-purity process pipelines.

Key Features and Advantages

Environmentally Safe & Compliant

• Asbestos-Free: Fully compliant with OSHA, REACH, and other global occupational safety and environmental regulations.

• Green Manufacturing: Reduced environmental impact during production and disposal, supporting sustainable operations.

High Durability & Reliability

• Exceptional Mechanical Strength: Aramid fiber reinforcement provides high tensile strength and excellent creep resistance, maintaining long-term sealing under fluctuating pressure and temperature.

• Исключительная химическая стойкость: Effective against oils, fuels, solvents, and a wide range of acids and alkalis.

Wide Thermal Range

• Operating temperature: –100°C to +300°C (short-term peak higher)

• Suitable for extreme cold, high-temperature steam, and thermal cycling environments.

Optimized Sealing Performance

• Low Stress Relaxation: Maintains initial bolt load better than traditional gaskets.

• High Resilience: Adapts to flange surface irregularities and compensates for thermal displacement.

• Low Permeability: Dense structure minimizes micro-leakage of gases and liquids.

Core Applications

• Petroleum & Gas: Flanges, valves, pumps, reactors, heat exchangers, and acid-resistant pipelines.

• Chemical & Petrochemical: Flanged connections in corrosive chemical production, storage, and transport equipment.

• Power & Energy: Steam systems, turbines, and boiler feed pumps in thermal, nuclear, and biomass power plants.

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

• High-End Manufacturing & Pharmaceutical: High-purity, clean-process pipelines requiring contamination-free sealing.
