Sealing large steel flanges in industrial or chemical processing operations can be complicated: factors like aggressive media, thermal cycling, uneven or corrosion-damaged sealing surfaces can compromise seal durability and longevity. While one-piece prefabricated gaskets can be an option, it can be a costly one: as well as price, there can be long lead-times and supply-chain issues to consider.

LARGE STEEL FLANGE SEALING CHALLENGES

  • High temperatures / thermal cycling
  • Alternating system pressures
  • Aggressive media
  • Uneven flanges / sealing surfaces

GORE GASKET TAPE SERIES 500

A spool of GORE® Gasket Tape Series 500 provides an immediate, cost-effective solution to sealing challenges that demand reliable performance and extended durability. This high-temperature gasket tape, with its industry-leading creep resistance, is designed to maximize the operational reliability of large-diameter steel flange applications, especially those with thermal cycling.

Applications

GORE Gasket Tape Series 500 creates a high-performance seal that fits any shape, instantly and reliably, to create a tight and long-lasting seal, in diverse applications with harsh process conditions — especially those that require a high-temperature sealing tape.

WHAT IS HIGH-TEMPERATURE GASKET TAPE GOOD FOR?

High-temp gasket tape is ideal for large steel flanges in any processes involving thermal cycling — that is, processes with inherently variable and/or extreme operating temperature ranges.
Thermal cycling affects the coefficient of expansion of the steel flanges and bolt-loads, and as well as the cold-flow and creep properties of the surrounding gaskets. Therefore, processes that involve thermal cycling require a gasket designed to withstand them, in order to maintain the integrity of the seal.

Processes involving highly-aggressive media or thermal cycling:

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

Large and/or non-standard steel equipment flanges:

  • Vessel and tank process flanges & manways
  • Large-diameter piping
  • Heat exchangers
  • Baffles
  • Non-Standard flanges (rectangular, …)

Material

  • 100% expanded PTFE (polytetrafluoroethylene), with multidirectional strength.
  • This product is supplied with an adhesive backer only to aid in the product installation.

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 70 bar (1000 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. To ensure optimal adhesive function, we recommend use within two years of date of purchase when stored under normal(2) conditions
