flexible graphite packing

Flexible graphite packing is braided from flexible graphite yarns, which are reinforced by cotton fiber, glass fiber, carbon fiber, etc.

Flexible graphite packing has a very low friction, good thermal and chemical resistance and high elasticity. Low friction does not damage shafts and stems.

Corrosion inhibitor acts as a sacrificial anode to protect the valve stem and the stuffing box.

Typical Application
 Flexible graphite packing is a multi-service packing capable of a wide variety of uses throughout a plant.
 It can be used in valves, pumps, expansion joints, mixers and agitators in high-pressure and temperature.
 Effective sealing is vital.

Prime Features
 Reinforced with glass fiber: high strength, lower cost
 Reinforced with carbon fiber: less weight loss
 Good thermal and chemical resistance and high elasticity.

Applications
For pumps and valves in extreme conditions or where the value of the best quality packing can be realised. Universal chemical resistance (sole exceptions are fuming nitric acid, oleum, aqua regia and fluorine.)

SERVICE CAPABILITY
Pressure Rating: 300 Bar	Rotary speed: 20m/s	pH range: 0-14
