Installation Guide

Partially remove the release liner and gently heat theunderlap approximately 150 mm (6") from the edge.

Centre the sleeve over the joint so that the sleeve overlapsbetween the 10 and 2 o'clock positions. Press theunderlap firmly into place and remove the remainingrelease liner.

Wrap the WLOX sleeve around the tyton joint. Gently heatthe backing of the underlap and the adhesive side of theoverlap. Finish wrapping the sleeve around the tyton jointpressing the overlap firmly into place.

Bulk Roll Closure

High Shrink WLOX is typically shipped in bulk rolls. Closuresare shipped either in bulk rolls or pre-cut. The adhesive isprotected from contamination by an inner liner. High Shrinksleeves are used with tyton, flange, coupling, and casingjoint applications.

Cut the required length (L) of WLOX sleeve material from the bulk roll. The length should be calculated usingthe circumference of the joint + 150mm

Cut the required width (W) of WLOX sleeve material from the bulk roll. The width should be calculated usingthe contours of the joint.

L = Joint O.D. + 150mm

W = W1 + W2 + W3 + W4 + W5Ensure that there is no damage, dirt or moisture on the sleeve.

Cut the required length (l) of closure material from the bulk roll.l + sleeve width less 5mm

Ensure that there is no damage, dirt or moisture on the closure.

1. Clean the overlap area of the sleeve where the closure isto be applied.2. Pre-warm the overlap area where the closure is toplaced.

1

Using broad strokes, begin shrinking the WLOX sleevearound the entire circumference of the larger end (bell) ofthe tyton joint. Continue heating from the centre of thesleeve until sleeve recovery is completed around the bell ofthe tyton joint.

If the closure lifts while shrinking, secure it with a glovedhand. Continue heating from the bell of the tyton joint to theother end (spigot) until recovery is complete.

16

In a similar manner, heat and shrink the remaining side.Shrinking has been completed when the adhesive beginsto ooze at the sleeve edges all around the circumference.

17

14

Continue shrinking from the bell of the tyton joint to thesleeve end. Sleeve recovery is complete when itconforms to the pipe.

15

Inspection

Visually inspect the installed sleeve for the following:a) Sleeve is in full contact with the tyton jointb) No lifts between sleeve and closurec) Adhesive flows beyond both sleeve edgesd) No cracks or holes in sleeve backing

20

Backfilling Guidelines

After shrinking is complete, allow the sleeveto cool to below the intended operatingtemperature of the pipeline before backfilling.To prevent damage to the sleeve, use selectedbackfill material, (no sharp stones or largeparticles) otherwise an extruded polyethylenemesh or other suitable shield should be used.

Warm the adhesive side of the closure until it becomesshiny. Centre the closure over the overlap. Using agloved hand press the closure firmly down onto theoverlapping sleeve.

Gently heat the closure and pat it down with a gloved hand.Repeating this procedure, move from one side to the other.Smooth any wrinkles by gently working them outwardfrom the centre of the closure with a roller.

While the sleeve is still hot and soft, use a hand roller tofirmly roll the sleeve surface and push any trapped air upand out of the sleeve, as shown above. If necessary,reheat to roll out air.

With a gloved hand, press down on the installed sleeve toensure the backing and sleeve are soft. If there are anycool spots, the sleeve should be reworked with additionalheat.
