Graphite with Tanged Insert (Spears Metal Sheet) Gasket Sheet, we also called by Reinforced Flexible Graphite gasket sheet, this material is a kind of sealing packing with excellent comprehensive properties. It overcomes the disadvantage of low intensity of the ordinary gaskets. It can be used in the condition of high temperature, high pressure and sealing.
Flexible Graphite is reinforced by tanged metal / metal foil, this material is a kind of sealing packing with excellent comprehensive properties. It overcomes the disadvantage of low intensity of the ordinary gaskets. It can be used in the condition of high temperature, high pressure and sealing.
Material has good compressibility and resilience, small stress relaxation, fine compensation function for unevenness of sealing surfaces and long working life. These plates are suitable for making gaskets of cylinders for air compressors, internal combustion engines and packing for different kinds of pipes and flanges.

L * W (mm): 1000*1000, 1500*1500,
Thickness (mm): 0.8/1.0/1.5/2.0/3.0/4.0/5.0
Gasket is cut precisely by DP5151 plates. The manufacturing process is easy. Installation as well as application is convenient. Having excellent sealing property, they are suitable for the media, such as: hot water, high temperature and pressure steam, hydrogen, ammonia, solvents, hydrocarbons, super-low temperature liquids, etc.
|Resilience||ASTMF-36 %||≥20(Tanged) / ≥15(Plate)|
|Leakage rate||ASTMF-37 cm3/s||1.0×10-3|
Application：Used as gaskets at the flange joints of different pipes, valves, pumps heat-exchangers, condensers, pressurized vessels, towers, manholes, hand holes, and to make gaskets for liquid level gages and crystallizers.
Except food and medicine touched media.
