The role and use of graphite rings
- 2019-03-30 -

The graphite ring is divided into a flexible graphite and a reinforced graphite ring.

The graphite ring is primarily used for sealing at mechanically rotating parts.

Graphite ring has high temperature, corrosion resistance and wear resistance

Flexible Graphite Packing Ring: The molded graphite graphite packing ring is made of low-swelling graphite tape by winding and molding. The scale is accurate, the density can be determined, and there is no added filler or adhesive. Generally, the cross section is square, and the wedge shape can also be V-shaped, and the latter two are suitable for high-pressure parts.

Flexible Graphite Ring: The flexible graphite tape or flexible graphite is used to prepare the filler, and the mold is restricted to ring products of different scales.

Scope of application: various corrosive chemical liquids, strong corrosive liquids such as strong alkali, hydrochloric acid, sulfuric acid, organic solvents, liquid oxygen, etc.

It is used in the sealing of flanges, valves, reactors and pumps in petroleum, chemical, chemical fiber, coal mining, power generation, metallurgical and other industrial fields.

Features: The ring can be added with wire and metal platinum according to user requirements.

Technical parameters: pressure (Mpa): 25 temperature (°C): -200 ~ 850 line speed (m / s): 30 PH value: 0 ~ 14

Performance and features: 1, self-humidity 2, high rebound coefficient 3, according to user needs, cut at 45 ° oblique.

Strengths: high temperature resistance, corrosion resistance, wear resistance, long life, low cost, easy to use, and remarkable effects.

Reinforced graphite ring: Reinforced swelled graphite packing ring participates in the expansion of graphite packing ring to participate in 304 steel strip, steel mesh, nickel platinum, etc. And a ring-shaped filler which is restricted by the mold.

Performance and features:

1, self-humidity

2, high rebound coefficient

3. Equipment can be used under high temperature conditions:

Universal packing

Industry:

Recommended equipment for petroleum equipment, power plants, chemicals, steel mills, etc.

Flexible graphite ring

The flexible graphite tape or flexible graphite is used to prepare the filler, and the mold is limited to ring products of different scales.

Graphite ring, graphite packing ring is a sealing ring made of pure flexible expanded graphite paper, which is restrained by spiral winding in the mold after being cut. It has excellent resilience, self-lubricity, corrosion resistance, heat resistance, low friction coefficient and long service life. Applicable equipment:

Packing seal of machine, pump, tube and valve. (Boiler feed water pump, hot oil pump and high pressure steam valve)

Applicable industry:

Recommended applications in petrochemical, metallurgy, electric power, atomic energy, aviation, etc.

Processing scale:

~900mm, special standards or various non-standards can be formulated according to customer requirements
