Expanded graphite packing | Flexible graphite packingDetailed Introduction pureGraphite Packing
Product model: SUNWELL P400
1. Pure graphite packing is commonly known as "expanded graphite packing" or "flexible graphite packing";
2. The flexible graphite disc is woven from low sulfur expanded graphite wire;
3. Cotton yarn is usually used as a reinforcing material;
4. The friction coefficient is low, and it will not wear down the pump shaft and valve stem.

Description:
inflateGraphite PackingWoven from expanded graphite wire with low sulfur content Reinforced with cotton yarn lining Has an extremely low coefficient of friction Good thermal conductivity Chemical resistance and high resilience According to different requirements, the following reinforcement materials can be used: glass fiber - high strength Low cost, carbon fiber - low loss on ignition
SUNWELL P400K: Corrosion inhibiting expanded graphite packing Protect the valve stem and pump shaft by adding sacrificial anode additives For example: Zinc powder

Application areas:
>1. Expanded graphite packing can almost meet various sealing requirements,
>2. Widely used in high temperatures Hydrogenation equipment under harsh working conditions such as high pressure papermaking. Power station Refining, etc,
>3. Other valves that require effective sealing Pump Expansion joint Mixing machine Blender, etc
Special note: Flexible graphite packing cannot be used for strongly oxidizing media When using flexible graphite packing as a stuffing box It is best to add SUNWELL P500R high carbon packing rings at both ends Prevent extrusion
