Description

Die -formed graphite rings are made of low-sulphur expanded graphite without any fillers or binders.Die -formed graphite rings are compressed in precise moulding tools to the required density. It is made from the high purity of the material(>99%),no special corrosion protection is required. In general,die -formed graphite ring has square section and also has V-shaped and wedge-shaped section. Die -formed graphite ring are suitable for high pressure sealing.

Application

Extremely suitable for valves handling thermic fluids, boiler feed water, solvents, acids & alkali, superheated & Saturated Steam handling control valves at high pressure. It can also be used in dynamic and static equipment handling organic & inorganic chemicals, in blowers, dryers, autoclaves, mixers & vessels.
