The graphite packing with antioxidant outer crocheted Inconel wire is reinforced by specially treated graphite strips and each metal mesh with Inconel wires outside, which is woven to form a dense and soft packing. The packing is treated with lubricant to reduce the friction on the rod, with stable chemical properties, easy molding, good lubrication performance and high thermal conductivity. It is not easy to harden and is inert to chemicals. There is no danger of extrusion and deformation of packing at high temperature, and the leakage control is consistent, which is suitable for seals of high temperature and high pressure valves.

① The temperature of temperature tolerance loss of different types of products is their highest adaptive temperature.
② When measuring carbon content and sulfur content, the metal materials should be stripped off before testing if the product reinforcement material contains metal materials.
