All Resources For GORE® Gasket Tape Series 1000

Overview

Glass-lined steel equipment is used by chemical processers to deal with aggressive media under demanding conditions. Yet the inherent demands of such systems – high temperatures, alternating system pressures, limited gasket loads and deviation of sealing surfaces – can make it challenging to maintain a tight, lasting seal.

GORE Gasket Tape Series 1000 addresses all the challenges of reliably sealing large glass-lined-steel flanges. Made of 100% expanded PTFE (ePTFE), this highly conformable 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.

GORE Gasket Tape Series 1000 is endorsed by De Dietrich Process Systems.

Endorsed by De Dietrich Process Systems

The endorsement by De Dietrich means GORE Gasket Tape Series 1000 has been approved for use and specified in new equipment.

"The GORE Gasket Tape Series 1000 is absolutely outstanding in sealing deviations, so even at low gasket stress, it shows extremely low emissions and gives us trouble-free mechanical completions," says Daniel Renger, R&D Director, De Dietrich Process Systems.

Outperforms envelope gaskets

Reliable and long-term seal

Opposed to envelope gaskets, GORE Gasket Tape Series 1000:

  • Provides chemical protection across the full flange width (100% ePTFE)
  • Enables longer maintenance cycles, as demanded by leading chemical producers

Optimal form for easy handling

Large envelope gaskets typically are fabricated offsite. This often results in long lead times, shipping, handling and inventory challenges, time-consuming and complex installation procedures.

The convenient spool format of GORE Gasket Tape Series 1000 offers the following advantages:

  • Gasket can be customized on-site
  • No fabrication lead-time required
  • Simplifies and speeds handling & transport
  • Adhesive backing enables easy installation
  • Faster, less complicated shimming tape technique for larger deviations
  • Reduces inventory costs

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

Outperforms other ePTFE tapes

Reliable and long-term seal

  • Seals more than 10 times tighter than other ePTFE gasket tapes
  • Allows full use of specification range of the glass-lined steel equipment
  • Enables longer maintenance cycles, as demanded by leading chemical producers

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

Outperforms filled PTFE gaskets

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

Reliable and long-term seal

Opposed to filled PTFE gaskets, GORE® Gasket Tape Series 1000:

  • Allows full use of specification range of the glass-lined steel equipment
  • Enables longer maintenance cycles, as demanded by leading chemical producers

Optimal form for easy handling

Large filled PTFE gaskets typically are fabricated offsite. This often results in long lead times, shipping, handling and inventory challenges, time-consuming and complex installation procedures.

Filled PTFE gaskets might be dovetailed for easier transport. This however often leads to increased emissions through the dovetail joints, as they are not overlapping.

The convenient spool format of GORE Gasket Tape Series 1000 offers the following advantages:

  • Gasket can be customized on-site
  • No fabrication lead-time required
  • Simplifies and speeds handling & transport
  • Adhesive backing enables easy installation
  • Reduces inventory costs

Technical Specifications

Technical Information

Material 100% expanded PTFE (polytetrafluoroethylene), with multidirectional strength
This product is supplied with an adhesive backer only to aide in the product installation
Chemical Resistance Chemical resistance to all media pH 0-14, except molten alkali metals and elemental fluorine. 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: from -60° C to 230° C (-76° F to 445° F); industrial full vacuum(1) to 10 bar (145 psi).
  • Maximum Use: -269° C to 315° C (-452° F to 600° F); full vacuum to 16 bar (230 psi) for flanges up to DN 2000/ASME 80".

Be aware that flange surface irregularities may cause high peak loads. Please contact De Dietrich if further guidance is required.

For applications outside the typical use range, Gore recommends an application specific engineering design calculation and extra care during installation.

Shelf Life ePTFE 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

Available Sizes

GORE Gasket Tape Series 1000 is available in multiple width, thickness, and spool length combinations.

Width Width Thickness Thickness Length Length
40 mm 1.5" 6 mm 1/4" 5 m 16'
55 mm 2" 9 mm 3/8" 10 m 32'
65 mm 2.5"     15 m 49'

All combinations of width, thickness, and length are available. Manufactured to metric dimensions.
Shim tape only available in above widths, 3 mm (1/8") thickness and 5 m (16') length.

Choose tape width to be the same or wider than the width of the flange. Use 6 mm (1/4") tape thickness for deviations up to 1.5 mm (0.060"), respectively 9 mm (3/8") tape thickness for deviations up to 2.3 mm (0.090") without shimming. For greater deviations, consider shimming with GORE Series 1000 shim tape.

Certificates & Application Information

TA Luft in accordance with VDI 2200

TA Luft test in accordance with VDI 2200 (06-2007)

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 DN200/PN10 steel flange with a gasket stress of 25 MPa was utilized.

TA Luft certificate is available for thickness 6 mm.
