High Temperature Graphite Gasket Sheets For Furnace And Heat Exchangers
High-Temperature Graphite Gasket Sheets for Furnace & Heat Exchangers
Optimize performance in extreme conditions with our advanced graphite gasket sheets, designed for high-temperature industrial applications such as furnaces, heat exchangers, steam systems, and exhaust manifolds. Available in thicknesses from 1.0mm to 6.0mm*, these sheets deliver unmatched durability and sealing efficiency under intense heat and pressure.
*Select the thinnest feasible material for your application to maximize cost-effectiveness.
Key Advantages:
-
Superior Heat & Pressure Resistance: Withstands temperatures up to 450°C+ and high-pressure environments, ideal for thermal cycling systems.
-
Reinforced Structure: Dual-layer pure flexible graphite encasing a 0.2–0.25mm perforated metal core (carbon steel/SS304/SS316) ensures no delamination.
-
Oil & Corrosion Resistant: Maintains integrity in oil-rich settings, perfect for cylinder heads, exhausts, and industrial gaskets.
-
Customizable Solutions: Choose from carbon content grades (95%–99%), sheet sizes (500x500mm to 1000x1500mm), and multi-layer bonding for thicker requirements.
