Flexible Graphite Packing
Flexible graphite packing are braided from flexible graphite
yarns, which are reinforced by cotton fiber, glass fiber, carbon fiber, etc.
It has a very low friction, good thermal and chemical resistance and high elasticity.
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
>Good thermal and chemical resistance and high elasticity.

Graphite Packing Reinforced with Metal Wire
Graphite packing reinforced with wire is braided from expanded
graphite yarns, reinforced with metal wire, normally reinforced with inconel wire.
It retains all the inherent benefits of flexible graphite packing.
The wire reinforcement provides greater mechanical strength, used for high pressure
and temperatures.
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.
>Excellent for use in steam turbines, high temperature motor-actuated valves
>High temperature and high pressure valve applications in general.
Prime Features
>It can be reinforced with nickel, stainless steel, copper, etc.
> Wide variety of uses throughout a plant
> Precaution: in oxidizing environment may use with anti-extrusion packing rings.

Graphite Packing with Carbon Fiber Corners
Graphite packing with carbon fiber corners is a multi-fiber packing,
braided from expanded graphite yarns and carbon fibers, the diagonally braided
from graphite yarn, reinforced in all four corners with carbon fibers.
The corners and body make the packing three times more resistant to extrusion
and increase the pressure handing capabilities compared to traditional graphite
packings.
There are multi inconel wires reinforced to create the packing with increased extrusion resistance capability.
Typical Application
>It can be used in many demanding applications, both dynamic and static
>Particularly suited for high temperature and high pressure service in valves, pumps, expansion joints, mixers and agitators of pulp and paper, power station and chemical plant etc.
Prime Features
>More resistant to extrusion
>Increase the pressure handing capabilities.

Graphite Packing With PTFE Impregnated
Graphite Packing with PTFE Impregnated is braided from
Expanded graphite yarns which impregnated with PTFE as a blocking
agent thus creating a non-straining packing. The yarns are reinforced
by textile fibers.
Typical Application
> Can be used in many demanding applications, both dynamic and static
>Particularly suited for high temperature and high pressure service in valves, pumps, expansion joints, mixer and agitators of pulp and paper, power station and chemical plant etc.
Prime Features
>Excellent cross-section tightness, structural strength
>Very lo friction-valve, wear resistant, yet gentle to shaft and stem.
