Specification of Graphite Seal Ring packing bulat
Graphite Seal Ring
Expanded expanded / expanded extended graphite rings made of ribbons, are wound and pressed to the required density achieved in accordance with the application. Thanks to its versatility, graphite allows its use under various conditions: it rejects almost all chemicals, aging, and does not become brittle because it does not contain binders. It is stable over time for compression and with various temperatures, thanks to its excellent resistance to heat changes. This ring is used as a fire-safe seal. In the air, they withstand very low temperatures and up to a temperature of about 550 ° C; in reducing or inert atmosphere to 3000 ° C. Its excellent shear properties ensure low wear on the shaft. Versions with these micro-perforated plates are able to withstand high pressures. They are manufactured with dimensions, trends, tolerances and densities according to customer requirements and ensure excellent seals once installed in their housing.
