Xixia Jinfangyuan Sealing Materials Co., Ltd. was established in 2004. It is located in Xixia County Industrial Cluster,Nanyang City, Henan Province.
This graphite packing is braided by graphite yarns, and the mechanical strength of the packing is enhanced by Inconel wires. The packing has the good properties of graphite packing, stable chemical properties, good lubrication performance, extremely low friction coefficient and high thermal conductivity, and is widely used 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.
