Descrption
Gasket jointing sheets are flat, sheet-like materials used to create gaskets — sealing components placed between two surfaces to prevent leakage of gases or fluids. These sheets are made from a range of materials, including compressed fiber, graphite, rubber, cork, PTFE (Teflon), and metal-reinforced composites. They are typically manufactured under high temperature and pressure to enhance durability, chemical resistance, and sealing performance.
Jointing sheets are cut into custom gasket shapes based on the requirements of the sealing surfaces and operating conditions (such as pressure, temperature, and chemical exposure).
Common Materials
Non-Asbestos Compressed Fiber (NACF): A blend of aramid fibers, fillers, and rubber binders.
Graphite: High temperature and chemical resistance.
PTFE (Teflon): Excellent chemical resistance and non-stick properties.
Rubber-based sheets: Neoprene, nitrile, EPDM for flexible and oil-resistant gaskets.
Uses
Industrial Sealing: Used in pipelines, flanges, heat exchangers, and valves to prevent leaks in oil, gas, and chemical industries.
Automotive Applications: Engine gaskets, exhaust systems, and transmission components to ensure fluid and gas containment
Power Generation: Boilers, turbines, and condensers often use gasket sheets to seal joints exposed to high pressure and temperature
Petrochemical and Refinery Plants: Resist corrosive chemicals and extreme conditions in refining processes.
HVAC Systems: Provide airtight seals in heating, ventilation, and air conditioning systems.
Food and Pharmaceutical Industries: PTFE and other food-safe materials used in sanitary environments to avoid contamination.
Water Treatment and Plumbing: Used in pumps, meters, and flanged joints for leak-proof water sealing.
