Description
<\/b>Seal-Wrap\u2122 is a casing end-seal wrapper consisting of a heavy woven\u00a0glass coated with a butyl mastic of high dielectric quality wrapped around the end of the casing and on the carrier pipe. It is then strapped
in place with stainless steel banding.<\/p>

End Use<\/b>
The Seal-Wrap system was designed by the Trenton Corporation toenable field personnel to readily replace existing \u201crubber-boot\u201d type end seals that are damaged prior to installation of casing filler.\u00a0<\/p>

Application Procedures<\/strong><\/p>

  1. \u00a0With a wire brush, clean the last 12\u201d of the casing pipe ends and the first 12\u201d of the carrier pipe to removeloose rust, coating, and dirt. Dry off all surfaces.<\/li>
  2. Brush Seal-Wrap Primer onto the cleaned areas of the carrier and casing to be covered with Seal-Wrap. Let dry until tacky.<\/li>
  3. Place one layer of Double-Faced Adhesive at the edge of the casing and one layer approximately 4\u201d from the end of the casing on the carrier pipe. Remove release paper from the Double-Faced Adhesive. This is the area where the banding will be applied.<\/li>
  4. Measure around outside circumference of the casing to determine length for a single wrap of Seal-Wrap, then add 6\u2033 to ensure that Seal-Wrap is cut long enough to allow for a 6\u2033 overlap. Apply one wrap of SealWrap around the carrier and casing end. One edge of the Seal-Wrap should be aligned with the farthest edge of the Double-Faced Adhesive on the casing. Remove release paper as you apply the Seal-Wrap.<\/li>
  5. Band securely in place, using one band and two buckles on both casing and carrier in the middle of the Double-Faced Adhesive. Use the banding tool to tighten bands until flush with the surface of the Seal-Wrap, then tighten both buckles with the supplied hexagonal wrench.<\/li>
  6. Cover buckles with small squares (approx. 6\u201d square) of Double-Faced Adhesive to prevent cutting of next layer. Remove release paper from Double-Faced Adhesive.<\/li>
  7. Apply a continuous double wrap of Seal-Wrap directly over the first wrap, making sure to start the second wrap in a different position than the first. Remove release paper as you apply the Seal-Wrap. (To determine the length of Seal-Wrap, double the casing circumference, then add 6\u201d for overlap.)<\/li>
  8. Apply one wrap of Double-Faced Adhesive centered over the edge of the casing end and one wrap centered over the edge where the Seal-Wrap meets the carrier pipe. Do not remove release paper from the DoubleFaced Adhesive.<\/li>
  9. Place two bands on the carrier pipe on either side of the first band. The band closest to the end of the casing should be over the Double-Faced Adhesive applied in Step 8.<\/li>
  10. Place two bands on the casing pipe on either side of the first band. The band closest to the end of the
    casing should be over the Double-Faced Adhesive applied in Step<\/li>
  11. Tighten all bands into place so they seat securely into the Double-Faced Adhesive and Seal-Wrap.<\/li>
  12. Let the seals cure overnight.<\/li>
  13. Apply up to 2 psi into top vent, then check for a strong airflow escaping out the lower end vent. This confirms there are no restrictions between vents.<\/li>
  14. Close off the lower end vent, pressure casing to up to 2 psi, and monitor for 15 minutes. If any air pressure holds, the test is complete and the casing is prepared. It is highly recommended to backfill before testing above 2 psi.<\/li>
  15. If casing is to be filled with wax, it is highly recommended\/critical that the ends of the casing are backfilled. The backfill will help support the seals, and help stop any minor leaks.<\/li><\/ol>

    Advantages<\/strong>
    Seal-Wrap is an efficient method for the replacement or repair of casing end seals that are either damaged or are being installed due to new construction.
    \u2022 Carrier does not have to be centered in the casing.
    \u2022 Covers any size casing up to 42\u2033.
    \u2022 Ideal for preparation of casing for filling.
    \u2022 Can be installed on existing pipe.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
