1. High and low temperature resistance, wide application range The filler is flexible graphite with a wide temperature range:200°C to 650°C, suitable for steam, high-temperature thermal oil, and low-temperature refrigerant pipelines; its high-temperature resistance far that of rubber and PTFE gaskets, making it the preferred choice for boilers and thermal pipelines. 2. High pressure resistance, strong elastic sealing The alternating winding structure of stainless tape and graphite, supported by a metal skeleton, can withstand medium to high-pressure working conditions; the graphite layer has excellent elastic recovery after compression, maintaining a continuous seal even with flange deformation or thermal expansion and contraction, making it suitable for high-temperature and high-pressure steam and chemical pipelines. 3. Corrosion resistance, high medium versatility Flexible graphite resistant to most acids, alkalis, oils, water vapor, and gases; paired with 304/316L stainless steel metal tape, it is rust- and universally applicable to chemical, power plant, thermal, and gas pipelines; unlike pure metal gaskets, the soft graphite filler provides better sealing. 4. Excellent sealing and leak prevention no seepage or leakage The metal steel tape provides support while the graphite acts as a sealing buffer layer; this combination of soft and hard materials can fill tiny scratches and uneven defects on flange sealing surface; once the flange is tightened, it fits closely, making the probability of gas, liquid, or steam leakage extremely low. 5. Thermal cycle resistance, to failure Pipelines frequently undergo alternating hot and cold cycles (starting and stopping boilers, heat exchange equipment), which easily cause ordinary gaskets to harden and crack; the composite structure of metal graphite in the winding gasket has good thermal stability, and repeated thermal expansion and contraction will not cause it to loosen or break, resulting in a longer service life. 6. Multiple structures adapt to different flanges Available in basic type, with inner ring, with outer ring, and with both inner and outer rings: The outer ring ensures positioning and prevents installation misalignment The inner ring prevents media from corroding the inner side of the gasket; It can adapt to plate flanges, raised face flanges, and tongue-and-groove flanges making installation convenient. 7. Wear-resistant, resistant to compression and crushing Pure graphite gaskets are soft and easily crushed; the metal winding skeleton limits the excessive compression of the layer, preventing material scattering or cracking under high-pressure tightening, and it is not easily damaged during long-term use. 8. Complete specifications, non-standard customization The national standard DN series is in abundant stock, and thickness, inner/outer diameters, and metal materials (304/316L/carbon steel) can all customized; it is universally applicable to heat exchangers, valves, and pressure vessels, offering high adaptability for engineering procurement. 9. High cost-performance ratio, long service life to pure PTFE gaskets and metal flat gaskets, it balances high-temperature and high-pressure resistance with sealing performance, offering a longer replacement cycle and reducing equipment downtime and maintenance costs. 10. No aging or hardening issues Unlike rubber gaskets that easily age, harden, and fail at high temperatures, graphite has stable chemical properties and will not deteriorate or lose elasticity under-term high-temperature working conditions.
