Graphite Sleeve

Graphite sleeve

Generally, graphite sleeves are tubular. It has a lot of advantages.

High temperature stability

Graphite sleeve can withstand thousands of degrees Celsius high temperature. In high temperature furnace and other applications, it works properly.

High surface reflectance

It is a good heat insulation component, and its chemical properties are stable.

Low friction coefficient

You can use it as self-lubricating sleeve, it is highly durable.

Excellent thermal conductivity

It is able to conduct heat quickly, which is important in many thermal management applications.

Good electrical conductivity

This makes it a potential application in the electrical and electronics fields, such as in some parts that require conductive and thermal materials.

And it is easy to process and cut. But how to cut graphite needs to choose the right tools and methods according to its material characteristics. In addition, graphite sleeve bearings use their low friction coefficient and self-lubricating characteristics to reduce friction losses And graphite copper sleeves are also a common form of application.

Types of graphite sleeves

Divided by heating method

Longitudinally heated graphite sleeves:

A common type of graphite sleeve, heated in an axial direction, generates heat through the current at both ends to warm the sample. The structure is simple, the cost is low, but the temperature uniformity is poor.

Transverse heating graphite sleeve:

The heating direction is perpendicular to the axis, and the special structure makes the tube uniformly heated. This can reduce the temperature difference and improve the analysis accuracy and precision. It is suitable for the analysis work with high temperature requirements and precise control.

Divided by performance

Ordinary graphite sleeve (non-pyrolytic) :

Processed from natural graphite materials, it has a certain high temperature resistance and is easy to oxidize at high temperature. It has simple structure and low cost. And is suitable for general analysis.

Pyrolytic graphite sleeve:

Made by special pyrolysis process, high purity, high crystallinity, high stability and mechanical properties at high temperatures. It can reduce gas escape and impurity adsorption, improve analytical sensitivity and accuracy. You can often use it for trace element analysis and analysis with high sensitivity requirements.

Uses of graphite sleeves

It has a wide range of applications.

Machinery industry

Graphite sleeve is an important sealing material in the mechanical industry. It has wear-resistant, stable sealing under high load and high speed conditions. Ensure the normal operation of equipment and extend life.

Shipping industry

In the Marine industry, you can use graphite sleeve for hull and other uneven surface sealing. It can ensure the safe operation of ships in harsh sea conditions. And you can use it in import and export water systems and other parts.

Petrochemical industry

Graphite sleeves plays an important role in the petrochemical industry. In the transport of corrosive media equipment, wear resistance, corrosion resistance to full play, prevent media leakage and equipment wear. You can also use it in the manufacture of corrosion resistant equipment.

Power industry

In the power industry, you can use graphite sleeve in boilers, steam turbines and other equipment sealing. Its high temperature resistance, pressure resistance, corrosion resistance makes it indispensable.

Laboratory applications

You can widely use graphite sleeve in laboratories, such as carrying and heating samples in atomic absorption spectrometers. And in other experimental devices to meet the needs.

In addition, you can also use graphite sleeve in the manufacture of automotive parts, aerospace high-performance components, biomedical devices. Using its high strength, high wear resistance, high corrosion resistance and other properties.
