LGRHDI Planigraph™

Κωδικός: LGRHDI Planigraph™

Features

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.

Composition

Pure expanded graphite 
Multilayers SS316L reinforcement

Applications

Graphite gaskets for flange RF, FF, LMF and LTG
