Graphite packing reinforced with INCONEL netting type EGZ/RR

Products > Packings for pumps and valves > Graphite packing reinforced with INCONEL netting type EGZ/RR

High-parameter valve packing braided of yarn made of natural, expanded graphite (cleanliness above 98%) strengthened with a braid of inconel netting with very high thermal, chemical and mechanical resistance. Additionally, sealing is enriched with electro-galvanic corrosion inhibitor.

Application

EGZ/RR packing is used mostly in the power sector for sealing barrier fittings or as a closing package at very high temperatures and pressures up to 500 bar, in contact with steam, oils, acids except for strong oxidizers, as well as in:

  • chemical industry – for fittings in chemically aggressive utilities,
  • petrochemical industry – resistance to oils and hydrocarbons.
