Other Names:The oil-resisting asbestos gasket sheet is also known as oil-resisting asbestos sheet, oil-resisting compressed asbestos fiber jointing sheet, oil-resisting CAF gasket sheet, oil-resisting paronite, and more.
Oil-Resisting Asbestos Gasket Sheets are expertly crafted from high-grade asbestos fibers and oil-resistant rubber, providing exceptional durability and sealing capabilities in environments exposed to oils and fuels. These gasket sheets undergo a meticulous compression molding process, ensuring a robust and reliable product suitable for various industrial applications.
Series and Material Composition:This product line includes NY150, NY250, NY300, NY400, NY510, and HNY300. These sheets are made from high-quality long asbestos fibers combined with oil-resistant synthetic rubber and heat-resistant packing materials, compressed into thick paper. They are designed for use in equipment handling gasoline, mineral oil, fuel, hot chemical solvents, and alkali media, providing effective sealing for pipeline joints.
Applications
These gasket sheets are specifically designed for use in systems handling oils, fuels, and other petroleum-based substances. They are ideal for sealing joints in pipelines, engines, and machinery, providing a secure and leak-proof seal.
Available Sizes:
- Thickness: Ranges from 0.3mm to 5mm.
- Common Dimensions: 1500 x 1500mm, 1500 x 1360mm, 1500 x 1000mm, and 1270 x 1270mm.
- Custom Sizes: Other sizes are available based on customer requirements.
Customization Options:
- Reinforcement: Steel wire net insertion is available for added strength.
- Surface Coating: Graphite coating can be applied on one or both sides for enhanced performance.
Packaging:The sheets are packed in wooden pallets, with net weights of approximately 1000 kg or 2000 kg per pallet, ensuring safe and convenient transportation.
