Graphite Gasket Solutions for Petrochemical Piping Systems

Product Overview

Expandable graphite materials, which include flexible graphite sheets, graphite foil, graphite paper, graphite tape, and graphite strip (paper), are engineered for use in critical industrial sealing applications. These materials are created by first subjecting natural graphite flakes to a chemical exfoliation process. After that, they are heated to high temperatures, causing them to expand into worm - like structures with a density of around 0.003g/cc. Through a rolling process, these structures are transformed into flexible graphite coils. The resulting expanded graphite coils are binder - and filler - free, which gives them a high level of purity. They also offer excellent resistance to corrosion, radioactivity, and a wide range of temperatures. Additionally, they have good compression resilience, self - lubricating properties, and are impermeable, making them well - suited for use in low - pressure sealing. When combined with metal sheets, they form graphite composite plates that can meet the specific needs of the petrochemical industry.

Key Advantages for Petrochemical Piping

  1. Chemical Resistance
    • The graphite materials can withstand aggressive chemicals such as sulfuric acid, hydrocarbons, and solvents, which are commonly found in petrochemical processes.
    • They have a high degree of purity, with a carbon content of over 99.9%, ensuring they won't contaminate the media being transported.
  2. Thermal Stability
    • These gaskets can operate effectively in extreme temperature ranges, from cryogenic levels as low as - 200°C to high temperatures up to 1650°C.
    • Their low thermal expansion coefficient helps maintain dimensional stability, even when there are rapid temperature changes in the petrochemical piping.
  3. Mechanical Durability
    • They can handle high pressures, with a compressive strength exceeding 50 MPa, making them suitable for use in high - pressure petrochemical piping systems.
    • The flexible graphite structure allows for easy conformability to uneven pipe surfaces, providing a reliable seal.

Applications in the Petrochemical Industry

  1. Piping Seals
    • They are used to seal flanges, valves, and fittings in refineries, petrochemical plants, and offshore platforms.
    • When combined with metal reinforcement, they can provide enhanced structural support in high - stress areas.
  2. Equipment Sealing
    • These gaskets are used in reactors, heat exchangers, and distillation columns to prevent leaks and ensure the integrity of the equipment.
    • Their self - lubricating properties reduce the risk of friction - induced wear in moving parts.
  3. Safety - Critical Systems
    • They are suitable for use in systems that handle hazardous materials, such as those containing hydrogen sulfide or chlorine.
    • They meet fire - safety standards, such as API 607 fire testing, providing an extra layer of protection in the petrochemical industry.

Available Specifications

  • Sizes:
    • Coils are available in widths of 1000mm or 1500mm and lengths of 30m, 50m, or 80m.
    • Plates come in sizes of 1000mm x 1500mm, with thicknesses ranging from 0.15mm to 5mm.
  • Density: The density of the materials can be customized between 0.8g/cm³ and 1.25g/cm³ to meet specific application requirements.
  • Customization: Special shapes, such as spiral - wound or corrugated designs, can be created to fit unique piping configurations.
