Mechanical seal industry

Main Features

Graphite molds widely used in the mechanical seal industry hold an important position in the industry due to their unique performance and advantages.
Main Features:
High thermal conductivity: Graphite has a high thermal conductivity coefficient, which can dissipate friction heat in time, reduce the temperature of the sealing end face, and improve reliability and service life.
Low linear expansion coefficient: Graphite has a low linear expansion coefficient, resulting in small thermal deformation, which helps maintain the parallelism of the sealing end face and improves thermal stability.
Good corrosion resistance: Graphite is chemically stable and can withstand corrosion from various acids, bases, salts, and organic compounds.
Self-lubricating: When graphite rubs against metal, it can form relative friction between the graphite layers, reducing the friction coefficient.

Product Applications

Graphite molds are widely used in various mechanical sealing products, such as graphite rings, graphite sealing rings, and graphite gaskets, and are key components in mechanical seals. They utilize the high thermal conductivity, low linear expansion coefficient, corrosion resistance, and self-lubricating properties of graphite to ensure the stability and durability of the sealing end face. These products can maintain good sealing performance even in harsh environments such as high temperature, high pressure, and high wear.

The application fields of mechanical seals are extensive:

Petrochemical:Used in pumps, valves, pipelines, etc., to ensure sealing stability and reliability.

Mechanical manufacturing:Applied in machine tools, hydraulic equipment, transmission equipment, etc., to ensure sealing performance.

Aerospace:Used in engines and hydraulic systems to meet extreme environmental sealing requirements.

Nuclear power industry:Flexible graphite sealing gaskets have good creep resistance, meeting nuclear power sealing requirements.

Food processing:Graphite self-lubricating bearings do not require grease lubricants, suitable for food processing equipment.

Other fields:Such as metallurgy, mining machinery, transportation, wind power generation, etc.
