Graphite Seal Ring

Graphite Seal Ring Manufacturers

The graphite sealing ring is usually a circular ring structure. Its advantages are outstanding.

Excellent chemical stability

It is inert to most chemical substances, and can be used in corrosive environment for a long time.

Excellente résistance aux hautes températures

It can withstand up to 800°C or higher temperature, suitable for high temperature conditions.

Low friction coefficient

It can effectively reduce the friction between the sealing surface, reduce energy consumption. And it has self-lubricating characteristics, no additional lubrication, reduce maintenance costs.

Good resilience

Even in long-term compression or vibration environment, it can maintain a tight seal.

In addition, its sealing properties are not affected by pressure fluctuations and can work stably under different pressure conditions.

Types of graphite seal ring

Ordinary pressed graphite seal ring:

The use of conventional pressing process, low production cost, suitable for general industrial equipment sealing. Such as ordinary pipe connection, general pump body seal, etc.. It can meet the common water, air, weakly corrosive gas and other media sealing needs.

Impregnated graphite seal ring:

After special impregnation treatment, resin, metal and other substances are filled into the graphite pores to enhance its mechanical strength and corrosion resistance. You can commonly use it in chemical, petroleum and other industries to seal highly corrosive liquids or gases. Such as sulfuric acid, hydrochloric acid and other media.

Sintered graphite seal ring:

Made by high temperature sintering process, it has higher densité and hardness, excellent wear resistance. It is suitable for high speed, high pressure and strict sealing requirements, such as high-speed rotating mechanical seal parts.

Uses of graphite seal ring

Petrochemical industry:

In refining units, chemical reactors, pipeline valves and other equipment, you can use it to seal a variety of corrosive liquids, gases. Such as crude oil, refined oil, organic compounds, etc., to prevent media leakage, to ensure safe production.

Power industry:

You can use graphite seal ring in steam turbine, water pump, pipeline and other parts, sealing steam, water, chemical agents and other media. To ensure the efficient and stable operation of power generation equipment, reduce energy consumption and environmental pollution.

Machinery manufacturing industry:

In the rotating shaft and reciprocating parts of various mechanical equipment, such as compressors, pumps, hydraulic cylinders, etc., it plays a sealing and dustproof role. It reduces equipment wear, extends service life, and improves mechanical efficiency.

Automotive manufacturing industry:

You can use graphite rings for sealing key components such as automotive engine, transmission and brake system. To ensure engine power output, smooth shift of transmission and reliability of brake system. And improve the overall performance and safety of vehicles.

Aerospace field:

With its high temperature resistance, low temperature resistance, lightweight and other characteristics, it meet the sealing requirements of aerospace equipment in extreme environments. Such as in the aviation engine, aircraft hydraulic system and other components, it ensures flight safety.
