Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement requirements that require the use of graphite rings, it is recommended to prioritize confirming key dimensional parameters such as inner diameter, outer diameter, and thickness to ensure compatibility with equipment seals or bearing components.
  • In application scenarios of high temperature or highly corrosive media, attention should be paid to the purity level and temperature resistance range of graphite rings. Generally, high-purity isostatic pressed graphite is more suitable for extreme working conditions.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and enterprises with industry data support or platform statistical information.
  • When purchasing in the chemical or metallurgical industry, it is recommended to combine the compressive strength and friction coefficient indicators of graphite rings to avoid premature failure caused by mechanical loads.
