Product Description
Graphite rings are used in sealing products for mechanical rotating parts.
English name: Graphite ring
Made from flexible graphite tape or woven flexible graphite packing, molded into rings of various sizes.
Suitable for media such as hot water, high temperature, high-pressure steam, heat exchange fluids, nitrogen, organic solvents, hydrocarbons, and low-temperature liquids.
Used in compressors, pumps, valves, chemical instruments, and meters.
Pressure MPa: 25
Temperature °C: -200850
Linear velocity m/s: 30
PH value: 014
Graphite rings are divided into flexible graphite rings and carbon-graphite rings.
Carbon-graphite rings are mainly used for sealing in mechanical rotating parts.
Carbon-graphite rings have the characteristics of high temperature resistance, corrosion resistance, and wear resistance.
Properties and characteristics of graphite rings:
1. Good self-lubricating properties
2. High rebound coefficient
3. Can be cut at a 45° angle according to user requirements
