At advanced production unit, provided rings are manufactured using quality assured raw material by our talented professionals. These rings are used for sealing purpose in valves and rotary equipment handling. Provided Graphite Moulded Rings are suitable for duties with heat transfer media, organic acids, hot waxes and other related products.
- Lowers the break-out friction for valve operation
- Can withstand high-temperature steam
- Excellent durability and easy installation
These are made from materials that compress easily, such as elastomers like nitrile, (NBR,) EPDM and silicone, as well as graphite, PTFE and fibrous materials. Their corrosion resistance is good but they are limited in the temperatures they can handle. Nitrile gaskets for example only work from -60 to 250Â°F (-51 to 121Â°C) and EPDM is only slightly better with a range of -70Â°F to 350Â°F (-57Â°C to 177Â°C). Silicone gaskets will however go up to 500Â°F (260Â°C) and PTFE is effective from cryogenic temperatures up to 450Â°F (232Â°C).
Full face gasket types are suitable for use with flat-face (FF) flanges and flat-ring gasket types are suitable for use with raised face (RF) flanges.
Soft gaskets are also limited in their ability to handle high pressures. The best applications are those involving sealing variable gaps as might be found around the doors of an electrical enclosure.
