High-Strength Graphite Gaskets

No.LL-GBG-03

Graphite composite gaskets, also known as reinforced graphite gaskets or high-strength graphite gaskets, are punched or cut from reinforced graphite sheets. They offer excellent corrosion resistance, resistance to high and low temperatures, good compression resilience, and high strength. Common inner-layer reinforcing materials for reinforced graphite gaskets include SS304, SS316, or tinplate, with a thickness of 0.1~0.127mm. The reinforcement forms include punched plate reinforcement, mesh plate reinforcement, and flat plate reinforcement. The commonly used material is 304 reinforced graphite.

Description

Core Features

Multi-Layer Composite Structure: Features multiple layers of high-purity flexible graphite interleaved with several SS304/SS316L tanged or foil inserts, providing far greater structural integrity than single-core gaskets.
High-Density Compression: Utilizes a higher-density graphite grade to resist crushing under extreme bolt loads while maintaining a gas-tight seal.
Superior Blowout Resistance: The multi-layered metal reinforcement acts as an internal skeleton, making the gasket virtually immune to high-pressure blowouts in critical pipe systems.
Extreme Thermal Stability: Maintains a reliable seal in temperatures ranging from $-200^\circ C$ up to $3000^\circ C$ in non-oxidizing atmospheres.

Product Features:

Possesses excellent corrosion resistance, resistance to high and low temperatures, adaptability to high and low pressures, good compression resilience, and high strength.
It can be cut into complex sealing gaskets, such as level gauge gaskets, flanges with bolt holes, and other special-shaped sealing gaskets.
Easy to install and not prone to damage, it is an ideal sealing product for the connection of sealing surfaces of large-diameter pressure vessel flanges.

Common Applications

High-Pressure Valve Bonnets: The primary choice for sealing high-pressure valves in the power and petrochemical sectors.
Large Diameter Flanges: Ideal for large heat exchangers and pressure vessels where high bolt loads are required to achieve a seal.
Steam Headers & Mainlines: Reliable for high-temperature steam distribution where pressure fluctuations are frequent.
Critical Refining Processes: Used in hydrocrackers and catalytic reformers, where safety and blowout prevention are paramount.
