Pure Graphite Gaskets


In businesses, pure graphite-based gaskets are used intensively in cases where the standard gaskets do not meet the specifications, especially in applications where the temperature is high (steam, hot oil, hot water, condensate line, etc.).

You can find more detailed information about our product groups regarding graphite gaskets by calling our company. Graphite is a form of carbon in which atoms are arranged in layers or layers. This allows them to glide easily over each other, giving a slippery feel when rubbed between finger and thumb. This lubricity or low coefficient of friction is beneficial in gasketing or sealing. When the joining surfaces are brought together, the graphite allows some slip. It accommodates any rotation or lateral movement while the clamping load continues without damaging the sealing material. When used dynamically or as a gland, the low friction properties of graphite provide an effective barrier while minimizing energy losses and heat generation.

Graphite is also a very soft material. But this allows it to flow into surface irregularities, which is what provides the sealing function. Like PTFE, graphite is highly inert. Even at high temperatures it resists the attack of most corrosive chemicals and does not contaminate them as well. It is possible to purchase graphite to use as a gasket. It is also used as a coating for some metal gaskets (Kammprofil gaskets are an example) where it provides excellent sealing performance as well as temperature and chemical resistance.

What is Graphite Gasket?

Graphite seals are small circular components that act as a mechanical seal. It is used to fill the gap between two connecting surfaces or parts. Often, gaps can form no matter how close you hold the two surfaces. These gaps can cause leakage from or into two different objects when moving or under compression. By installing a gasket in the zone, you can create a tighter fit alignment and maximize performance levels.

What Does Graphite Gasket Do?

Graphite is often used in high-temperature and high-pressure environments and is commonly used in steam cycle or exhaust applications. Graphite gaskets, on the other hand, provide a higher performance sealing than asbestos-free joints in these conditions.

Graphite has a low friction surface. In extreme conditions, it can withstand high pressures and temperatures. Graphite is a type of carbon that can provide a low friction gasket sheet surface. It provides excellent durability to the gaskets. In addition, graphite performs well in harsh environments such as areas with high temperature or high pressure.

How Does Graphite Gasket Operate?

Graphite gaskets have a number of properties that make them ideal for certain applications. While there are many other materials on the market that offer their own levels of protection against excessive temperature and general corrosion, graphite gaskets offer an overall package of properties that are 100% unique.

Graphite gaskets take temperature tolerance to whole new levels. Depending on the grade of graphite used in the manufacture of the gaskets, temperatures can go as low as -20 degrees Celsius and up to several thousand degrees. Graphite is a superior choice where extreme temperatures are present. With their strong thermal resistance, they also have excellent resistance to thermal shock. Thermal shock is a type of damage that occurs when components are subjected to rapid temperature changes, which can significantly affect their performance.

The graphite gasket is incredibly resistant to corrosion regardless of the pressure or heat encountered at the time. Graphite maintains its integrity where others will fail.

Graphite’s mechanical strength is also outstanding, making it an excellent choice in heavy-duty environments or where long-term reliability is important.

What are the Benefits of Graphite Gasket?

Graphite gaskets dissipate the heat and prevent the gasket from burning. They have excellent compressibility and can withstand high temperatures. They do not rub or become brittle. Graphite coatings allow the seal to move without damage.

Graphite is a form of carbon. It is the same element that forms diamonds. It is strong, inert and withstands extreme temperatures and pressures, but what makes graffiti special is its slickness. In graphite, carbon atoms are formed in layers that can slide over each other. This helps gasketed joint to be closed because the material moves easily to fill uneven spaces and picks up flange deformation or surface imperfections.

Where is Graphite Gasket Used?

Graphite gasket can be used in many different industries as they can withstand oils, gases, key tones, hot and cold liquids and hydrocarbons. The places where graphite gasket can be used include cooling towers, heat exchangers, petrochemical plants, electrochemical applications, chemical plants, high pressure pipes, equipment using hot oil and cryogenic environments.

What are the Features of Graphite Gasket?

Graphite gasket is suitable for use with steam and natural gas. It has good ozone resistance. Graphite gasket, which can hold temperatures up to 3000 degrees in non-oxidizing atmospheres, has high corrosion resistance. It also has a long storage life.

High-temperature applications are difficult for many gasket materials. Non-graphite gasket materials such as Nitrile, Silicone, PTFE and others will only support temperatures up to a certain level. For example, Nitrile gaskets will serve application temperatures up to about 95°C, while silicone and PTFE will serve application temperatures up to 200°C and 260°C, respectively. For applications involving temperatures higher than this, graphite gaskets are often preferred.

Graphite, a form of carbon, is an inert material that resists chemical attack even at high temperatures. Because it is an inert material, it has a low tendency to react with other substances or become contaminated. Graphite also has a low coefficient of friction, which is beneficial when used to seal joints. Gasket made of graphite sheet easily adapts to loading forces when flange surfaces are tightened.

The graphite sheet used to manufacture the gasket will support high temperatures. Typical temperature ranges include -240°C to 510°C and pressures up to 2000 psi in an oxidizing atmosphere. High-purity graphite sheet can become brittle and therefore high-purity sheet is often reinforced with metal core inserts to provide additional strength and stability.
