Graphite Packing

Gland Packing & Ring Packing | Graphite Packing

A requirement of any gasket is the ability to recover under variable loads.The effects of pressure and temperature fluctuations, the temperature difference across the flange face, together with flange rotation, bolt stress relaxation and creep, demand a gasket with adequate flexibility and recovery to maintain a seal under variable and uneven loading. The spiral wound gasket meets these requirements.

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.

 

APPLICATION:

 

High-performance pure graphite valve and pump packing suitable for plant wide applications with excellent chemical and temperature resistance. Manufactured from expanded graphite for outstanding sealing ability.

It is Suitable for high pressure, high temperature applications and Offering excellent sealing and operational reliability for both Original Equipment Manufacturers and plant users alike

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 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.

 

APPLICATION:

 

It is 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.

Super-high Temperature & Pressure Graphite Packing

Description:

It is a premium expanded pure graphite (carbon content 99.5 to 99.9%) fiber yarn braided packing, each yarn of which is reinforced with multiple Inconel wires, thoroughly incorporated with non-metallic inorganic passive corrosion inhibitor and special oil lubricating agents. Each yarn is jacketed with Inconel wire mesh. The reinforcement and jacketing with Inconel wire mesh in each yarn enables the packing to withstand extreme mechanical stress and cyclic loads.

 

APPLICATION:

 

Very high sealing a ­ciency even on oscillating valve stems without much wear and tear. The reinforcement & jacketing of Inconel wire enhances the strength of packing & also to withstand high temp. & pressure. This special jacketed graphite fiber is designed for high performance sealings even at elevated temperature & pressure.
