Industrial graphite rings, with a purity of ≥ 99.8% and a density of ≥ 1.9 g/cm³, are high-performance sealing materials specially designed for high-temperature and high-pressure industrial environments.
Core Advantage
As an industrial graphite ring, its high-density structure (≥ 2.2 g/cm³) has a thermal expansion coefficient as low as 5 ppm/℃ at a temperature of 400°C, significantly reducing the risk of seal failure and ensuring long-term stability.
The professional surface treatment technology enhances the corrosion resistance by 35%, and the measured data show that the service life is extended by 40% in a strongly acidic environment (pH ≤ 2) (verified in the 2024 refining project of Sinopec).
Typical Application Scenarios
Petroleum refining equipment
Industrial graphite rings are used for sealing in reactors and pipelines, capable of withstanding a pressure of 150 bar and a temperature of 400°C, with a leakage rate lower than 0.01%, ensuring continuous production.
Chemical production system
In the chlor-alkali industry, industrial graphite rings provide high reliability sealing, preventing chlorine corrosion. The service life of a single unit has been extended from 2 years to 3 years (verified by Sinopec South China Base).
Quality Assurance And Customized Services
It has obtained the ISO 9001 international certification. Each batch undergoes dual tests for density (±0.03 g/cm³) and purity (±0.1%), with a 100% pass rate.
It supports small-batch customization (100-500 pieces), and can complete technical responses within 24 hours, precisely adapting to the specific working conditions of customers.
