Graphite Plug

Advantages of graphite plugs

The common forms of graphite plug include cylindrical, conical and custom-made special shapes, and its advantages are very significant.

Excellent high-temperature resistance

It can maintain structural stability and reliable performance within an extreme temperature range of approximately -200°C to 600°C.

Extremely stable chemical properties

Good resistance to most corrosive media such as acids and alkalis.

Extremely low coefficient of friction

It can achieve a self-lubricating effect during use.

A certain degree of flexibility

It is convenient for installation and adaptation to holes of different specifications.

Low friction and self-lubricating properties

It can effectively reduce wear, decrease maintenance frequency, and enhance the reliability and efficiency of equipment operation.

Good thermal and electrical conductivity

It can quickly conduct heat and prevent local overheating and it has application potential in some special scenarios where requiring electricity. For example, in some high-temperature conductive sealing environments, it can simultaneously meet the dual requirements of sealing and conductivity.

Uses of graphite plugs

Chemical industry

In chemical pipeline systems

You can use it as sealing components at the end of pipelines and inspection openings to prevent the leakage of corrosive chemical media and ensure production safety.

On equipment such as reaction vessels and storage tanks

It can withstand various harsh chemical environments such as strong acids and strong alkalis. So you can use it to seal sampling ports, feeding ports and other parts.

Energy field

In the high-temperature steam pipeline system

You can use it to seal the connection parts of the pipelines. It can resist the erosion of high-temperature steam and high-pressure environments, and ensure the stable operation of the system.

In the production process of new energy batteries

Graphite plug also can be used as sealing and conductive components in battery electrode manufacturing equipment. With the excellent electrical conductivity and chemical stability, it can enhance the quality and efficiency of battery production.

Metallurgical industry

In high-temperature smelting equipment

You can use it to seal the holes in the furnace body to prevent the leakage of high-temperature gases. And due to their high-temperature resistance, it can withstand the extreme temperature environment inside the furnace.

In metal heat treatment equipment

Graphite plug can also be used to seal the openings of the furnace chamber. It ensures the uniformity of temperature and the stability of the atmosphere in the heat treatment process.

Aerospace field

Its characteristics of being lightweight, heat-resistant and resistant to extreme environments meet the strict requirements of the aerospace field of materials. Therefore, you can also use it in sealing high-temperature components of aero engines and thermal protection systems of spacecraft.

Laboratory equipment

In high-temperature furnaces, vacuum equipment, and chemical experiment apparatus, graphite plugs also play an important as seal and connect components. They provide a stable environment for the experimental process and prevent gas leakage or the entry of external impurities.
