Products Description

Graphite pressure seal ring is resistant to high temperatures, corrosion and self-lubricating. They are high-performance sealing elements suitable for sealing needs under extreme working conditions.

There are many kinds of sealing elements on the market, and the emergence of graphite pressure seal rings has solved the pain points of easy wear and failure of traditional metal or rubber seals.

Graphite seal rings are often used as shaft end seals for high-temperature and high-pressure reactors, compressors, pumps and valves in petrochemical and coal chemical plants. For example, the seals used in ethylene cracking units need to be able to withstand high temperatures and highly corrosive media, while the chemical inertness of graphite sealing rings allows them to operate for a long time in this environment and avoid safety accidents caused by media leakage.

In addition, graphite seal rings can also be used in rocket engine fuel pumps, and such graphite rings often require metal impregnation processes. Its use can ensure airtightness under extreme temperature differences and support the repeated ignition requirements of the engine.

Graphite seal rings can also be used in some special equipment, such as screw extruders, high-temperature sintering furnaces and other equipment. Its use solves the dynamic sealing problem in polymer melts or powder metallurgy environments. At the same time, the excellent self-lubricating property of graphite sealing ring significantly extends the maintenance cycle of the equipment.
