Expanded Graphite Packing, also known as **flexible graphite packing**, is made by weaving flexible graphite wire. This type of packing offers excellent self-lubrication, high thermal conductivity, a low friction coefficient, and strong adaptability. It is highly flexible, durable, and provides effective protection for the pump shaft and valve stem. Depending on the application, it can be reinforced with materials such as carbon fiber, copper wire, 304 stainless steel, 316L, or Yinzhi nickel alloy wires to enhance performance.
**Basic Description of Expanded Graphite Packing:**
1. Pure graphite packing is commonly referred to as "expanded graphite packing" or "flexible graphite packing."
2. The flexible graphite packing is typically woven from low sulfur expanded graphite wire.
3. Cotton yarn is often used as a reinforcing material to improve strength and stability.
4. It has a very low friction coefficient, which helps prevent wear on the pump shaft and valve stem.
**Description:**
The expanded graphite packing is woven using low sulfur expanded graphite wire, with cotton yarn used as an inner reinforcement. It features a very low coefficient of friction, excellent thermal conductivity, chemical resistance, and high resilience. For different applications, various reinforcing materials can be added, such as glass fiber (high strength, low cost) or carbon fiber (low loss on ignition).
**SUNWELL P400K:**
This is a corrosion-resistant expanded graphite packing that includes sacrificial anode additives like zinc powder to protect the stem and pump shaft.
**Application Areas:**
1. Expanded graphite packing can meet almost all sealing requirements in various industrial environments.
2. It is widely used in harsh conditions such as high temperature and high pressure, including hydrogenation equipment, papermaking, power plants, and oil refining.
3. It is suitable for valves, pumps, expansion joints, mixers, and other equipment requiring reliable sealing.
**Important Note:**
Flexible graphite packing should not be used in environments with strong oxidizing media.
