GORE® GR Sheet Gasketing

Applications

GORE GR Sheet Gasketing is a tough, dimensionally-stable and chemical-resistant gasket sheet for sealing steel pipe and equipment flanges in a wide range of applications and process conditions. It reliably seals flanges with rough surfaces, and is ideal for flanges that require complex gasketing shapes or larger gasketing sizes.

Processes utilizing highly-aggressive media, as in:

• Chemical processing
• Pulp and paper manufacturing
• Mining and minerals
• Semiconductor manufacturing
• Power generation

Large, complex or non-standard steel equipment flanges in:

• Columns
• Reactors
• Turbines
• Heat exchangers
• Tanks
• Pipe flanges

Material: 100% expanded PTFE (polytetrafluoroethylene), with multidirectional strength

Chemical Resistance: Chemical resistance to all media pH 0-14, except molten alkali metals and elemental fluorine.

Operating Range: The maximum applicable pressure and temperature depend mainly on the equipment and installation.

• Typical use: -60 °C to 230 °C (-76 °F to 445 °F);
  industrial full vacuum(1) to 40 bar (580 psi)
• Maximum use: -269 °C to 315 °C (-452 °F to 600 °F);
  full vacuum to 210 bar (3000 psi)
   

For applications outside the typical use range, Gore recommends an application specific engineering design calculation and extra care during installation. Also, consider retorquing after a thermal cycle when the equipment has returned to an ambient temperature condition. Please contact Gore if further guidance is required.

Shelf Life: Expanded PTFE is not subject to aging and can be stored indefinitely.
