1 Carbon Graphite Seal Ring
Graphite seal ring are made of low-sulphur expanded graphite without any filler and binders. They
are compressed in precise moulding tools to the required density. Due to the high purity of the
material, no special corrosion protection is required. In general, it has square section ,V-Shaped
and Wedge-shaped section.Mould from pure flexible graphite with reinforcement, the insert materials
stainless steel foil or mesh etc.
2 Die formed Graphite Ring
Die formed ring are made of low-sulphur flexible graphite or flexible graphite packing. Embeddeing
metallic increase in strenghth, it has square section and also has V-shaped and wedge-shaped. can
bear violent alteration of temperature and pressure.It is ideal packing for valves and static seal in
almost all applications. used as stan-alone packing or in combination high carbon fiber anti-extruction
packing rings.
Application: All kinds of corrosive chemicals, liquids, strong alkali, hydrochloric acid, sulfuric acid
and other strong corrosive liquids, organic solvents, liquid oxygen, etc., used in petroleum, chemical
industry, chemical fiber, coal mining, power generation, metallurgy and other industrial the area of
flange, valve, reaction kettle, pump seal.
