tanged graphite gasket
A tanged graphite gasket represents a sophisticated sealing solution that combines the exceptional properties of flexible graphite with the structural integrity of a metal tang insert. This innovative design consists of high-purity graphite foil reinforced with a metallic tang core, typically made from stainless steel or carbon steel. The metal tang provides enhanced mechanical strength and stability while maintaining the superior sealing characteristics of graphite. The gasket's construction allows for excellent compression recovery and resistance to high temperatures, making it suitable for operations up to 450°C in oxidizing environments and 750°C in non-oxidizing conditions. The tanged metal insert prevents over-compression and lateral movement of the graphite, ensuring reliable sealing performance under varying pressure conditions. These gaskets excel in applications involving thermal cycling, high pressures, and chemical exposure, making them particularly valuable in petrochemical processing, power generation, and industrial manufacturing. The unique composition also provides exceptional resistance to creep relaxation and maintains seal integrity over extended periods, significantly reducing maintenance requirements and improving operational efficiency.
