OEM Customized Graphite Mechanical Sealing Ring circel graphite Hollow High purity Graphite Block

Graphite and its products have excellent characteristics such as high-strength acid resistance, corrosion resistance, high temperature resistance of 3000℃ and low temperature resistance of -204℃, and are widely used in metallurgy, chemical industry, petrochemical industry, high energy physics, aerospace, electronics, etc. The specific characteristics of graphite are roughly as follows:

1. Super high temperature resistance

The melting point of graphite is 3850±50°C and the boiling point is 4250°C. Even if burned by ultra-high temperature arc, the weight loss is very small, and the thermal expansion coefficient is also very small. The strength of graphite increases with the increase of temperature. At 2000°C, the strength of graphite doubles.

2. Graphite products have good thermal conductivity and thermal shock resistance. Graphite can withstand drastic changes in temperature without being damaged when used at room temperature. When the temperature changes suddenly, the volume of graphite does not change much, and cracks will not occur.

3. Graphite products have chemical stability and corrosion resistance. Graphite has good chemical stability at room temperature and is not corroded by any strong acids, strong alkalis and organic solvents.

4. Graphite products are environmentally friendly and healthy, no radioactive pollution, and high temperature resistance. Carbon needs to go through at least a dozen days and nights of graphitization in a high temperature environment of 2000-3300 degrees to become graphite. Therefore, the toxic and harmful substances in graphite have long been released, and it is very stable at least within 2000 degrees.

5. Graphite products have good adsorptivity. The interstitial structure of carbon makes carbon have good adsorption properties, so carbon is often used as an adsorption material to adsorb moisture, odors, toxic substances, etc.

Because the High purity graphite ring is made of the same material, the performance of the material is uniform in all parts of the seal ring, there is no defect of leakage and separation of the combined seal ring, and there is no possibility of electrochemical corrosion. Most of the soft rings are made of graphite, and various alloy steels such as bearing steel (GCr9), high-speed steel (W18Cr4V) and other alloy steels (such as 1140Cr, 3Cr13, etc.) can be used in the manufacture of hard rings, and some alloy cast irons are also used.
