Expanded Graphite Sheet LGRHDI Planigraph™

Composition

The graphite gasketing sheets LGRHDI are the greatest material to make gaskets for high temperature and high pressure services for RF, FF, LMF and LTG piping and heat exchangers flanges. LGRHDI shows a great value of relaxation with an excellent mechanical strength.

Characteristics

Pure expanded graphite
Multilayers SS316L reinforcement

Applications

Graphite gaskets for flange RF, FF, LMF and LTG
