Graphite rings for industrial sealing, with a temperature resistance of ≥ 250℃, a friction coefficient of ≤ 0.12. Specifically designed for high-temperature sealing scenarios, with excellent corrosion resistance. Direct supply from the original factory. Leading industry density. Suitable for key fields such as chemical and energy industries.
Core Strengths
Polymer composite sealing technology
The graphite rings used in industrial sealing are produced through a graphite-epoxy resin composite process. The friction coefficient is ≤ 0.12, the tensile strength reaches 35 MPa, and the temperature resistance range is -200°C to 300°C (tested according to ASTM D638).
Industry density advantage
Only 4 factories worldwide possess the technology for large-scale production of industrial sealing graphite rings. China Zhongke Materials Technology (national-level certification) has an annual production capacity of over 2.5 million pieces, covering the high-end markets in Europe and North America.
Direct supply from the source factory
The entire chain from the graphite base to the sealing structure is controllable. It has passed ISO/TS 16949 certification, and the sealing performance meets the ASTM D2292 standard, with the service life extended by 2-3 times (actual data).
Typical Application Scenarios
Chemical equipment
Sealing components for high-temperature and high-pressure reaction vessels, resistant to acid and alkali corrosion, with a sealing lifespan of ≥ 10 years (case: a certain chemical plant in Germany).
Energy equipment
Gas turbine shaft seals, resistant to high-temperature oxidation, with stable sealing performance (case: an energy company in the United States).
Precision machinery
High-speed gearbox shaft seals, with an oil resistance reaching ISO 4927 standards, and a 60% reduction in friction loss (measured data).
