GRAPHITE SEALS FOR STEAM AND HIGH TEMPERATURE · BELPAGRAF
Belpagraf is pure, expanded, mineral graphite and it is laminated with a rust blocker.
Owing to its excellent resistance to high temperatures and pressure, it is ideal for making steam gaskets, exhaust gaskets, gaskets for boilers, etc.
- It covers the majority of uses in petrochemical and industrial refineries; it is long lasting and is effective at different temperatures.
- It is fire-proofing certified according to the API 607 4th edition and BAM requirements
- We have various qualities, depending on whether they incorporate the inox metal insert, or not, and whether they have rust block or not.
