It is braided from graphite yarn with metal alloy wire and glass fiber casing like shell outside.
All-metal coated structures greatly increased the erosion resistant of packing, make packing more compact, more robust, long life.
It is competent to ultra-high temperature, high pressure conditions of the steam valve sealing.
>Electric power plant combustion furnace door;
>Chemical plant high-pressure valve sealing;
>Not suitable for highly oxidizing agents.
