Graphite Stopper Head

Advantages of graphite stopper head

Extremely strong thermal stability

It can remain stable within a wide temperature range of -200°C to 1600°C (non-oxidizing environment).

Stable chemical properties

It can withstand the corrosion of most acid and alkali media.

Excellent sealing performance and low friction coefficient

It can effectively prevent fluid leakage and cause little wear to the contacting components.

Sturdy structure

This makes it have good impact resistance and a long service life.

Certain thermal conductivity

It can assist in heat dissipation while maintaining sealing, which is particularly important in the sealing of high-temperature equipment.

Types of graphite stopper head

According to your specific requirements, it can be processed to meet your size specifications. Usually, it comes in various shapes such as cylindrical, conical or irregular.

Cylindrical graphite stopper head

This is the more common form and it has a regular structure, which is suitable for most circular interfaces. You can often use it for sealing the openings of pipes and storage tanks, and it can be customized according to the interface size.

Conical graphite stopper head 

It is suitable for interfaces requiring gradual sealing, which can better fit the conical channels. And it will enhance the sealing effect, so it is often used for sealing some special-shaped pipes.

Special-shaped graphite stopper head

This is processed according to the specific interface shapes of certain equipment, which is suitable for irregular openings. It can meet the sealing requirements in special working conditions, such as the special feed ports of reaction vessels.

Uses of graphite stopper head

Metallurgical industry

It can not only seal to prevent the leakage of high-temperature molten metal or slag, but also control the outflow volume by adjusting the position. And it can withstand high-temperature conditions and the erosion of molten metal, so you can use it for the steel outlet and slag outlet of the smelting furnace, etc.

Chemical Industry

It can resist corrosion from acidic and alkaline media, prevent leakage, and ensure production safety. You can use it as sealing components for the feed ports and maintenance openings of equipment such as reaction vessels.

Mechanical manufacturing industry

You can also use it for temporary sealing of hydraulic and pneumatic system pipelines, or as an auxiliary seal for valves. It can reduce equipment failures caused by leakage and extend maintenance intervals.

Energy industry

It plays a sealing role at the pipe interfaces of high-temperature and high-pressure equipment such as boilers and steam turbines. It can adapt to extreme environments and ensure the stable operation of the energy system.

Photovoltaics and semiconductor industry

High-purity graphite stopper head can be used for the inlet and outlet sealing of silicon material melting equipment. It can prevent impurity contamination and ensure the purity of photovoltaic or semiconductor materials.
