Description: die formed ring are made of low-sulphur expanded graphite without any fillers or binders. They are compressed in precise moulding tools to the required density. Due to the high purity of the material (>98%), no special corrosion protection is required. In general, it has square section and also has V-shaped and wedge-shaped section, the rear two kinds style are suitable for high pressure sealing.
PPLICATION:
Reinforced Die formed Graphite Ring Molded from pure flexible graphite with reinforcement, the insert materials stainless steel foil or mesh etc. are available on request. To protect against oxidation, the stainless steel cap is necessary.
APPLICATION:
It has all properties of expanded graphite, can bear violent alteration of temperature and pressure. It is ideal packing for valves and static seal in almost all applications. Can be used as stand-alone packing or in combination high carbon fiber anti-extrusion packing rings, except when stems are severely damaged.
