What is carbon fiber packing

Carbon fiber packing is a type of braided packing used for sealing applications in various industrial sectors. It is composed of carbon fiber yarns that are braided in a specific pattern, resulting in a dense and flexible packing that is resistant to high temperatures, high pressures, and harsh chemical environments.
The carbon fiber yarn used in carbon fiber packing is made from a high-strength and lightweight material that is known for its excellent thermal conductivity, low thermal expansion, and high resistance to abrasion and corrosion. Carbon fiber packing is designed to maintain its sealing properties even in extreme temperatures ranging from -200°C to 600°C.
Carbon fiber packing is commonly used in high-temperature applications such as valves, pumps, and turbines, where conventional gasket materials may not be suitable. It is also used in applications that require resistance to harsh chemicals such as acids, alkalis, and organic solvents.
The braiding pattern of carbon fiber packing can vary depending on the specific application and the required level of compression. The packing is typically braided in a square or rectangular pattern, which allows for good contact between the packing and the shaft, creating a tight seal.
One of the key advantages of carbon fiber packing is its ability to withstand high temperatures and pressures, which makes it ideal for use in industrial applications that require a reliable and durable sealing solution. Carbon fiber packing is also resistant to wear and tear, and can withstand repeated cycles of compression and relaxation without losing its sealing properties.
Another advantage of carbon fiber packing is its low friction coefficient, which reduces wear on the packing and extends its lifespan. The low friction coefficient also helps to minimize shaft wear and reduce power consumption, resulting in improved efficiency and reduced maintenance costs.
