Graphite Packing Ring:

Graphite packing ring is formed by molding flexible graphite packing strip, and can be reinforced by adding metal materials.

It is mainly used to seal the valves, pumps, elastic joints and other parts in petrochemical, thermoelectric, nuclear power and general industrial applications. Its functions are stable and reliable.

Standard: Ф8—Ф1100mm

Working pressure: 43.1MPa

Working temperature: -200—650℃

Main products: valve special low torque packing ring, pitting resistant packing ring, high temperature resistant packing ring, nuclear-class packing ring, etc.

Usage: Graphite packing ring is made by perforating or cutting pure graphite sheet. It has excellent corrosion resistance, high/low temperature resistance, excellent compression resilience and high strength. Various special-shaped gaskets are widely used in pipe, valve, pump, pressure vessel, heat exchanger, condenser, generator, air compressor, exhaust pipe, refrigerator, etc.

Graphite packing ring, also known as flexible graphite packing ring is formed by molding graphite strip surrounded by stainless steel wire mesh and treating its surface with lubricant, graphite powder and corrosion inhibitor. It is suitable for mechanical seal applications in petroleum, chemical, power generation and other industries.

Primary usages of graphite packing ring

● It is directly attached to the surface of various metal and nonmetal materials, playing the role of anti-adhesion, heat resistance, corrosion resistance, sealing and so on.

● It is processed into graphite packing ring (used for static and dynamic sealings such as various valves and pumps).

● It is used as the central filling material of metal surrounding gasket and the lining material of steel, iron and copper jacketed gasket (for pipe flange, vessel end cover, sealing).
