Graphite Washer

Advantages of graphite washer

Outstanding thermal stability

It can maintain stable performance within a wide temperature range of -200°C to 600°C , which is suitable for extreme temperature environments.

Chemical inertness

It exhibits excellent corrosion resistance to most acids, bases and organic solvents.

Self-lubrication

Its coefficient of friction is low, which can reduce wear on sealing surfaces and extend service life.

Good flexibility

It is easy to compress and rebound, capable of adapting to uneven sealing surfaces, thus ensuring a tight fit.

High sealing performance

It can still maintain good sealing effect under high pressure or vacuum conditions.

Thermal and electrical conductivity

It can quickly conduct heat and current, and is suitable for sealing scenarios requiring heat management or electrical conductivity.

Types of graphite washer

Classified by purity

Standard purity graphite washer

Its carbon content is approximately 99%, so its is suitable for general industrial sealing requirements such as pipes, valves, etc.

High purity graphite washer

Its carbon content is over 99.5%, which can be used for fields with extremely high purity requirements such as semiconductors.

Classified by shape

Flat graphite washer

This is the most common circular washer, suitable for static sealing of flanges, pumps, valves, etc.

Graphite washer with embedded structure

Such as metal reinforced graphite washer, it combines a metal framework, enhancing strength and compressive resistance.

Special-shaped graphite washer

You can customize it to specific shapes according to equipment requirements, such as rectangular, elliptical, etc.

Uses of graphite washer

Chemical industry

With the excellent corrosion resistance, it can effectively prevent medium leakage, which ensures production safety and equipment stability.

Energy industry

In oil transportation pipelines

You can use graphite washer as flange sealing components to resist the corrosion of crude oil and high-pressure environments. Thus ensuring the sealing of the transportation system.

In natural gas equipment

It has high-temperature and high-pressure resistance properties, so you can also use it for interface sealing. In natural gas storage tanks and compressors, it can help improve the operational safety of the equipment.

Mechanical industry

Pipeline sealing

Due to the excellent sealing performance, thermal resistance, and flexibility, it is an ideal material for manufacturing sealing components of pipelines, pumps, valves, etc. You can use it in industries such as automobiles, power, and paper-making, which effectively prevents liquid and gas leakage.

Equipment interface sealing

Because of the good compression and rebound performance, you can sue it as sealing components for various mechanical equipment interfaces. It can reduce leakage caused by vibration and pressure changes, and improve mechanical operation efficiency.

Food and pharmaceutical industry

Reactor vessel sealing

You can use it as a sealing material for food and pharmaceutical reactors because of its strong chemical inertness. It does not contaminate the materials, so it can ensure product purity, prolonging the service life of the equipment.

Refrigeration industry

Refrigeration equipment sealing

In refrigeration systems, it can withstand low temperatures, the chemical properties of refrigerants, and other harsh environments. You can use it as sealing components for pipes and components to improve the efficiency and stability of the refrigeration system.
