The packing ring is shaped through compression of expanded graphite paper wound up in the mold. It has a performance comparable to other sealing materials. It can be used separately or together with other packing as static sealing in places where there is high temperature and pressure, and many other media (except strong oxidizing acids) prevail.
Max.working temperature:
600?(in non-oxidized atmosphere)
450?(in oxidized atmosphere)
Max.working pressure:
6.3 Mpa (Used separately)
25.0Mpa(Used with other packings)
PH value: 0~14
