    Glass-Lined Steel Sealing Challenges

    Gore_Series_1000_installed_on_reactorThe composition and properties of glass-lined steel make it a desirable material of construction for processes that involve aggressive media that operate under rigorous conditions. Yet the harsh demands of this equipment can make it challenging to maintain a tight, lasting seal primarily due to limited gasket loads and deviation of sealing surfaces.  Sealing difficulties become an even greater issue for large flanges.  Envelope gaskets or filled PTFE gaskets that incorporate compressible materials are frequently used but only provide a partial solution.  The inconsistency in quality of these gaskets may eventually lead to premature gasket failure, with consequences that range from problematic to catastrophic, including:

    • Leakage/emissions
    • Equipment damage
    • Production downtime
    • Risks to personnel safety

     

    A High Performance Sealing Solution

    GORE® Gasket Tape Series 1000 (S1000*) addresses all the challenges of reliably sealing large glass-lined steel flanges.  Made of 100% 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 to minimize leakage and provide chemical protection across the full width.

    Endorsed by De Dietrich Process Systems

    Recommended for its superior performance and durability, GORE Gasket Tape S1000 is available  through De Dietrich Process Systems. Our endorsement of this product means Gore Gasket Tape Series 1000 has been approved for use, specified in new equipment, and offers users the opportunity for technical and installation support.

     

    How does GORE Gasket Tape S1000 Work?

    The barrier core quickly creates a region of full density as load is applied (see diagram below).  Therefore, even at relatively lower flange loading like in glass-lined steel, an optimized tightness can be achieved (more than 10 times tighter than other ePTFE gasket tapes).

    GORE Gasket Tape S1000 Applications

    GORE Gasket Tape S1000 gasket tape is optimized for chemical processes utilizing highly aggressive media (e.g. specialty chemicals, agricultural products, polymers) and in mining and mineral applications. This gasket solution is designed for use in large (greater than DN600/24”) or non-standard flanges typical of columns, mixer vessels, reactors, storage and receiver tanks.   

     

     

    GORE Gasket Tape S1000 Features

    GORE Gasket Tape S1000 provides a reliable, long-term seal with outstanding conformability to deviations even at low gasket stress.  Additional product attributes include:

    • Chemical resistant ePTFE construction ensures consistent quality and full chemical compatibility throughout the life of the gasket
    • Customizable on-site (skiving technique), with no hassles of offsite gasket fabrication compared to large envelope and filled PTFE gaskets (e.g. long lead times, shipping, handling and inventory challenges).
    • Ability to maintain load in operation (Creep resistance)
    • Crush resistance
    • Flexible tape for easy handling and installation, featuring adhesive backing that enables quick and easy installation to prevent troublesome and delayed start-up.
    • Tape lengths suitable to large flanges (>24” diameter)

     

    Field Test Results

    Gore_Series_1000_cross_sectionGORE Gasket Tape S1000 gasket tape has been put to the test in real, demanding work environments.   The image on the right is a cross section of GORE Gasket Tape Series 1000 after service in challenging process conditions, illustrating how effectively the barrier core stops leakage.  Further field experience shows that the barrier core creates a tight seal that even impedes highly permeating media.  The following graph compares the leakage rate of GORE Gasket Tape S1000 with other ePTFE tape and gasket designs indicating that when put to the test, GORE Gasket Tape S1000 can easily pass the “bubble test” for trouble-free start-up.

    GORE Gasket Tape S1000 Technical Specifications

    • Material: 100% expanded polytetrafluoroethylene (ePTFE) with multidirectional strength.
    • 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 vacuum1 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 us 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.
      • 1) Absolute pressure of 1 mmHg(Torr) = 133 Pa = 1.33 mbar = 0.019 psi
    • Chemical Resistance: Chemical resistance to all media pH 0–14, except molten alkali metals and elemental fluorine.

    Gore_Gasket_Tape_Product_Sizes_Chart

    All combinations of width, thickness, and length are available.  Manufactured to metric dimensions.  Shimming 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 for deviations up to 1.5 mm (0.060”); 9 mm (3/8”) for up to 2.3 mm (0.090”).  For greater deviations, consider shimming.  Further details are available in the Installation Instructions.

     

    Options

    • 3 mm (1/8”) shims for deviations out of recommended range. 
    • Technical and installation support
