SIGRAFLEX® HOCHDRUCK PRO
Description:
SIGRAFLEX® HOCKDRUCK PRO (SGL Carbon patent) is composed of expanded graphite sheets impregnated with corrosion inhibitor, purity > 99.85% and smooth sheets in AISI 316L steel of 0.05mm.It can be installed in the presence of surface pressures up to 400 N / mm^2 and operating pressures up to 250 bar.
The main characteristics are: very high pressure resistance, high resistance to bursting, high rigidity, compression stability, good elastic return over time, wide thermal resistance.
- Ideal for use at high temperatures and pressures and with R45 substances
- High compressive strength value
- Meets the Atex requirements (CEI 31-35 guide)
- Graphite with a purity of 99.85%
