What is a Graphite Sheet with SS Tangled?

Graphite Sheet with SS Tangled is a high-performance composite sealing material consisting of a flexible graphite matrix reinforced with an embedded metal tanged sheet You can think of it as the sealing industry's equivalent of reinforced concrete: the graphite acts as the high-performance "cement," providing a matrix that is resistant to heat and corrosion, while the metal tanged plate serves as the "rebar," significantly enhancing the material's mechanical strength.

Primarily used to manufacture gaskets, it is an ideal sealing solution for flange connections in pipelines, valves, pumps, and pressure vessels across sectors such as petrochemicals, mining, and power generation.

Core characteristics of Graphite Sheet with SS Tangled

Graphite Sheet with SS Tangled are composite materials formed by bonding high-purity expanded graphite with a metal tang core (perforated metal sheet) through rolling or molding. This design offers the following key advantages:

Superior Mechanical Strength: The embedded metal tang core—typically made of 304 or 316 stainless steel—serves as the primary reinforcing skeleton. It overcomes the inherent brittleness and low tensile strength of pure graphite sheets, imparting greater toughness and impact resistance to the material.

Excellent Sealing Performance: The graphite layer possesses outstanding compressibility and recovery, effectively compensating for flange surface irregularities or thermal deformation. It maintains a stable, long-term seal even under conditions of rapid temperature fluctuation and resists aging or embrittlement. In standard tests, these gaskets demonstrate a compressibility exceeding 30% and a recovery rate of at least 15%.

Resilience in Extreme Conditions: Inheriting the excellent properties of graphite, these sheets are suitable for a wide temperature range of -200°C to +550°C and can withstand high pressures of up to 500 bar. They also exhibit exceptional corrosion resistance, making them compatible with virtually all media across the pH range of 0–14 (with the exception of a few strong oxidizing agents).

Main application areas of Graphite Sheet with SS Tangled

Petroleum and Chemical Industry: Sealing for piping and equipment handling various oils, solvents, and corrosive chemical media.

Power and Energy Industry: Sealing for high-temperature and high-pressure components such as steam systems, boilers, and heat exchangers.

Shipbuilding: Sealing for systems involving seawater, fuel, hydraulic oil, and more.

Piping Systems: Flanges connecting sections of process piping.

Valves and Pumps: Connections between valve bodies and piping, as well as pump inlets and outlets.

Pressure Vessels and Boilers: Manholes, handholes, nozzles, and other areas requiring frequent disassembly or subject to high pressure.

Specifications and Selection Recommendations

Dimensions: Common sheet sizes include 1000 x 1000 mm and 1500 x 1500 mm, with thicknesses typically ranging from 1.0 mm to 5.0 mm; custom sizes are also available upon request.

Selection Tips:

Medium and Temperature: These are the two most critical factors. Verify that the medium does not react with the graphite (e.g., strong oxidizing acids) and ensure the operating temperature falls within the material's tolerance range. For specialized applications such as the nuclear industry, select high-purity, nuclear-grade materials.

Pressure Rating: Under high-temperature and high-pressure conditions, consider using thicker gaskets or those with special structural features (such as edge reinforcement/cladding) to ensure a reliable seal.

Relevant Standards: Manufacturing may be based on standards such as the Chinese National Standard GB/T 19675.1-2005 and the Machinery Industry Standard JB/T 6628-2008.
