CNAF GASKET
CNAF (Compressed Non-Asbestos Fiber) gaskets, also commonly known as CAF (Compressed Asbestos Fiber) gaskets, are types of gaskets used in various industries for sealing applications. However, due to health and safety concerns associated with asbestos, modern gaskets are typically labeled as CNAF to indicate that they are made from non-asbestos materials. Here’s a specification for a CNAF gasket:
- Product Name: CNAF (Compressed Non-Asbestos Fiber) Gasket
- Material: Compressed Non-Asbestos Fiber (typically made from aramid fibers, cellulose fibers, and inorganic fillers bonded with elastomers or resins)
- Type: Full-Face, Ring, or Sheet Gasket
- Temperature and Pressure Rating:
- Temperature: Typically suitable for temperatures ranging from -100°C to 250°C (depending on material composition and application)
- Pressure: Typically suitable for low to medium-pressure applications, ranging from vacuum to around 1500 psi (depending on material composition and application)
- Sizes Available:
- Full-Face Gaskets: Available in standard ANSI, DIN, JIS, or custom sizes to match flange dimensions.
- Ring Gaskets: Available in standard ASME B16.5, API 6A, or custom sizes to match flange dimensions.
- Sheet Gaskets: Available in various thicknesses and sheet sizes for custom cutting.
- Features:
- Non-Asbestos Composition: Made from non-asbestos fibers, offering a safer alternative to traditional asbestos gaskets.
- Resilience: Exhibits excellent resilience, sealing properties, and resistance to compression set under a wide range of temperature and pressure conditions.
- Chemical Resistance: Resistant to a wide range of chemicals, oils, fuels, and solvents, depending on the specific material composition.
- Conformability: Conforms well to irregular flange surfaces, providing a reliable seal even in applications with minor flange imperfections.
- Versatility: Suitable for use in various industries, including oil and gas, chemical processing, power generation, water treatment, and more.
- Application:
- Ideal for sealing applications in pipelines, pumps, valves, compressors, heat exchangers, and other equipment where leak-free seals are essential.
- Commonly used in industries where the presence of asbestos is prohibited or restricted due to health and safety regulations.
- Standards Compliance: Manufactured to meet or exceed relevant industry standards and specifications, such as ASME, ANSI, DIN, JIS, API, ASTM, and others, depending on the application requirements.
