Overview

Chemical processors use glass-lined steel pipe and equipment to deal with aggressive media under demanding conditions. Yet the inherent demands of such systems can make it challenging to maintain a tight, lasting seal and prevent leaks that can pose hazards to the equipment, and to the working environment.

GLASS-LINED STEEL SEALING CHALLENGES
  • High temperatures
  • Alternating system pressures
  • Limited gasket loads
  • Deviations in flanges / sealing surfaces
GORE GASKET TAPE SERIES 1000

GORE Gasket Tape Series 1000 addresses all the challenges of reliably sealing large glass-lined flanges. Made of 100% expanded PTFE (ePTFE), this highly conformable sealant tape is chemically inert, and highly resistant to creep, cold flow and clamp-force loss. Its proprietary barrier core maintains an extra-tight seal even at low loads.

Performance Benefits

With Gore’s advanced ePTFE material technology and its proprietary barrier core, our Series 1000 gasket tape enables high-performance, high-reliability sealing.

Why consider ePTFE tape

Unique barrier core technology

  • Barrier core engineered to amplify the available load.
  • Seals more than 10 times tighter than other ePTFE gasket tapes. (Especially important where glass-lined reactor safety is a consideration.)

Outstanding conformability to deviations

  • Seals deviations even at low gasket stress.
  • Easily passes the bubble test, for trouble-free mechanical completion (MC) or start-up.

Optimal form for easy handling

  • Gasket can be customized on-site.
  • No fabrication lead-time required.
  • Convenient spool format simplifies and speeds handling & transport.
  • Adhesive backing enables easy installation in ambient temperatures from 2–50 °C (36–122 °F).
  • Faster, less complicated shimming tape technique for larger deviations.
  • Reduces inventory costs.
Gore Gasket Tape Series 1000 is easy to install whether industrial glass-lined equipment surface temperatures are that of a hot summer day,d or nearly freezing.

Installation temperature window is effective from hot summer conditions to almost freezing surface temperature.

Reliable and long-term seal

  • Barrier core creates a tight seal that impedes even highly-permeating media.
  • Provides chemical protection across the full flange width (100% ePTFE).
  • Tape is engineered to resist creep and clamp-force loss.
  • Allows full use of specification range of the glass-lined steel equipment.
  • Enables longer maintenance cycles, as demanded by leading chemical producers.
Even after exposure to aggressive media, this cross-section of GORE Gasket Tape Series 1000 still retains its sealing integrity.

Cross-section shows how well GORE Gasket Tape Series 1000 endures in challenging conditions with aggressive media.

GORE GASKET TAPE SERIES 1000 OUTPERFORMS THE COMPETITION

Outperforms envelope gaskets

Three images of envelope gaskets show how they can degrade and fail in glass-lined steel equipment containing aggressive media.

Aggressive media can cause common envelope gaskets to degrade or fail, creating risks for personnel and potential for equipment/corrosion damage, production downtime and related costs.

Problems with large envelope gaskets: Solutions with Gore’s Series 1000 gasket tape:
Material mix doesn’t offer overall chemical resistance: Microcracks on the PTFE envelope will allow diffusion which can destroy the inner core Provides chemical protection across the full flange width (100% ePTFE)
Limited seal reliability/durability over time and process cycles can require more frequent maintenance and downtime. Exceptional creep resistance enables longer maintenance cycles, as demanded by leading chemical producers.
Limited conformability to flange deviations. May complicate mechanical completion or delay start-up. Outstanding conformability to deviations enables reliable sealing even at low gasket stress. Easily passes the bubble test, for trouble-free mechanical completion (MC) or start-up.
Typically fabricated off-site, with long lead times. Customize gasket on-site — no fabrication lead-time.
Time-consuming/complex installation procedures. Easy handling, and adhesive backing enables easy installation. Faster, less complicated shimming tape solution for larger flange deviations.
Related supply-chain challenges (availability, shipping/logistics complications). Assured supply; simplifies and speeds transport and handling.
Inventory costs and issues. Reduces inventory carrying costs.

 

Outperforms other ePTFE tapes

Problems with other ePTFE gaskets: Solutions with Gore’s Series 1000 gasket tape:
Limited seal tightness especially at low stress. Seals more than 10 times tighter than other ePTFE gasket tapes.
Gaskets’ limited durability may require glass-lined steel equipment at less than full specification range. Allows full use of entire specification range of the glass-lined steel equipment.
Requires shimming even at lower deviations. May complicate mechanical completion or delay start-up. Outstanding conformability to deviations enables reliable sealing even at low gasket stress. Easily passes the bubble test, for trouble-free mechanical completion (MC) or start-up.
Limited seal reliability/durability over time and process cycles can require more frequent maintenance and downtime. Exceptional creep resistance enables longer maintenance cycles, as demanded by leading chemical producers.

 

Outperforms filled PTFE gaskets

Problems with filled ePTFE gaskets: Solutions with Gore’s Series 1000 gasket tape:
Typically fabricated off-site, with long lead times. Customize gasket on-site — no fabrication lead-time.
Related supply-chain challenges (availability, shipping/logistics complications). Assured supply; simplifies and speeds transport and handling.
May be dovetailed for easier transport, which can result in emissions through the non-overlapping dovetail joints. Product supplied on a convenient spool. Installs using skived joints to maintain a tight, reliable seal.
Inventory costs and issues. Reduces inventory carrying costs.
Time-consuming/complex installation procedures. Easy handling, and adhesive backing enables easy installation. Faster, less complicated shimming tape solution for larger flange deviations.
Limited conformability to flange deviations. May complicate mechanical completion (MC) or delay start-up. Outstanding conformability to deviations enables reliable sealing even at low gasket stress. Easily passes the bubble test, for trouble-free mechanical completion (MC) or start-up.

Certificates & Application Information

TA Luft

For the TA Luft(1) test, the seal is installed in a DN40/PN40 steel flange, usually with a gasket stress of 30 MPa. The flange is then exposed to a defined temperature for minimum 48 hours. After cool down, leakage rate is measured over a period of at least 24 hours. The test pressure is 1 bar helium.

The ultimate final leakage rate after a test duration of 24 hours must remain below 10–4 mbar*l/(s*m) for the seal to qualify according to TA Luft.

No test procedure currently exists for glass-lined steel. Therefore Gore has conducted modified tests for this certification. A DN 200 / PN 10 steel flange with a gasket stress of 25 MPa was utilized.

TA Luft certificate is available for thickness 6 mm.
