Flexible Graphite Packing

Graphite packing is a robust sealing material that is commonly utilized in systems featuring valves, faucets, and packing boxes, as well as machines with waterproof mechanical components. This sealing material is suitable for use in both static valve stems and moving joints. Due to its exceptional chemical resistance, outstanding thermal conductivity, and superior lubrication, graphite packing is a preferred choice in numerous industries. It is valued for its reliability, cost-effectiveness, and ease of installation.

To manufacture graphite packing, a considerable number of graphite filaments are intertwined by twisting, resulting in graphite packing strands known as "yarns." The yarns are then interwoven to increase their tensile strength and durability. After weaving, manufacturers apply agents such as PTFE to coat the yarns, enhancing their chemical resistance. Finally, sealants are applied to the woven packing, effectively sealing the filaments and enhancing the overall sealing capability of the packing.

Graphite packing is a popular choice in industries that deal with acids and oils due to its chemical and high-temperature resistance. Its durability makes it an ideal sealing material for the fuel, chemical, and natural gas industries. Refineries can significantly reduce mechanical maintenance costs by utilizing graphite packing since it has an indefinite lifespan and provides exceptional valve protection. Moreover, it is self-lubricating and virtually wear-free, which makes it the top choice for achieving optimal valve sealing and protection.
