Graphite Packing

Flexible Graphite Packing

  Description:Braided from low-sulphur expanded graphite yarns, which are reinforced by cotton or glass fiber. It has a very low friction, does not damage shafts or stems. It shows good thermal and chemical resistance and high elasticity.

 

CONSTRUCTION

Other reinforcement materials are also available:

Glass fiber--------High strength, lower cost

Carbon fiber------Less weight loss

APPLICATION:

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, high-temperature hostile environments of hydrocarbon processing, pulp and paper, power stations, refineries and industries where effective sealing is vital.

Precaution: in oxidizing environment.

Recommendation:

Use preferably with high carbon fiber anti-extrusion packing rings.

Graphite Packing reinforced with Inconel wire

  Description:Braided from low-sulphur expanded graphite yarns, reinforced with Inconel wire. It retains all the inherent benefits of CAZ-240 pure graphite packing, good thermal and chemical resistance, very low friction, the wire reinforcement also provides greater mechanical strength, Normal for valve with high pressure. Other metal materials, nickel, stainless steel etc. on request.a multi-service packing capable of a wide variety of uses throughout a plant. It is particularly suited for use in high temperature, high pressure steam service. In addition, it can also handle most chemicals, acids and alkalis. It is excellent for use in steam turbines, high temperature motor-actuated valves and for high temperature and high pressure valve applications in general.

 Precaution: in oxidizing environment.

Recommendation: May use with carton anti-extrusion packing rings.

Graphite packing with PTFE impregnation

  Description:Made of expanded flexible graphite, which are reinforced by textile fibers, with PTFE impregnation. Compared to traditional graphite packing, it has excellent cross-section tightness, structural strength and very low friction-value, wear resistant, yet gentle to shaft and stem.

APPLICATIONG:
 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.
