Supagraf® HD Pro

Supagraf HD Pro is a high temperature / high pressure multi‑layer high grade graphite sealing system.

TYPICAL APPLICATIONS
  • CO2
  • Cryogenic
  • HPI/CPI
  • Hydrogen

Supagraf HD Pro is a high grade TA-Luft approved gasket sheet made of multi-layer stainless steel and highly oxidation-resistant flexible graphite. The layers of graphite and stainless steel sheets are laminated with a high strength non-adhesive joining system. The impregnation of the sealing layers reduces leakage and improves handling.

This product has been independently 3rd party tested and is validated by James Walker for use in hydrogen service

  • Ultra pure high grade graphite
  • TA-Luft approved (high-grade sealing system)
  • Multi-layer 316L steel reinforcements with no adhesive laminating system
  • Suitable for high gasket stress applications

  • Piping flange gaskets, heat exchangers, boilers, reactors, vessels and OEM equipment
  • Suitable for sealing in applications with thermal cycling such as sealing molten salt media in solar power generation plants
  • Compatible with HP steam, hydrocarbons and a wide range of chemicals and gases, including CO2 and hydrogen, within HPI and CPI industries
  • High pressures (up to 200 bar)
  • Suitable for ASME, EN, JIS, DIN flanges

  • Maximum temperature: +550°C (+1022°F)
  • Minimum temperature: -196°C (-321°F)
  • Maximum pressure: 20 MPa/200 bar (2900 psi)

  • TA Luft (complies with the tightness criteria of 10-4 mbar, l/m.s of VDI guidelines 2200 and 2440)
  • API 6FB fire safe approved
  • MESC SPE 85/203 compliant

  • Available thicknesses 1 mm to 4 mm
  • Sheet size of 1500 mm x 1500 mm (gaskets can be produced up to a diameter of 1500 mm in one piece)

The operational life span of graphite at high temperatures might be limited due to media or environmental influences. Please contact us for continuous exposure in oxidising environments above +450°C.
