Special graphite packing for high temperature and pressure
Description
This style graphite packing is braided from graphite yarn with metal alloy wire and greatly improved the extrusion ability of graphite.
All-metal coated structures greatly increased the erosion resistance of packing, make packing more compact, longer life.
It is competent to ultra-high temperature, high pressure conditions of the steam valve sealing.
Application
Suitable for high temperature & pressure and low linear velocity sealing packing of valve,kettle and pump.
