Temagraph HP is high integrity, multilayer sheet material with outstanding mechanical strength. It is designed for higher pressure and temperature applications and for flange connections where resistance to high bolt loadings is required. Temagraph HP is manufactured from the high purity expanded graphite foil reinforced with a number of perforated steel inserts (thickness 0,05mm) without the use of adhesive. This sandwich design confers high compressive strength to the material making it suitable for tongue and groove and exchanger applications as well as variety of demanding applications in the oil, refining and chemical industries. The multilayer composition also ensures that the product adapts well to a variety of flange surfaces.
