The graphite packing with outer crocheted Inconel wire is braided by pure graphite yarns, and each graphite yarn is reinforced by Inconel wire metal mesh, and the effect is enhanced by a barrier agent. The packing is stable in chemical properties, soft, easy to form, good in lubrication, high in thermal conductivity, difficult to harden and 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.
