Continue heating from the centre toward one
end of the sleeve until recovery is complete. In
a similar manner, heat and shrink the remaining
side.
18
Shrinking has been completed when the
adhesive begins to ooze at the sleeve edges
all around the circumference. Finish shrinking
the sleeve with long horizontal strokes over
the entire surface to ensure a uniform bond.
19
While the sleeve is still hot and soft, use a hand
roller to gently roll the sleeve surface and push
any trapped air up and out of the sleeve, as
shown above. Continue the procedure by also
fi rmly rolling the closure with long horizontal
strokes from the weld outwards.
With the green-yellow coloured adhesive side
facing down, fi rmly press the entire closure
seal into place. Ensure that the closure is
centred evenly over the underlap-overlap
sleeve seam. If necessary, add additional heat
to the closure underside in cold conditions,
using a low fl ame intensity.

15
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 outward from
the centre of the closure with a roller.

After shrinking is complete, allow the sleeve to cool to less than 90°C prior to laying (for offshore applications, product
can be water quenched).

Using the appropriate sized torch, begin at the
centre of the sleeve and heat circumferentially
around the pipe. Use broad strokes. If utilizing
two torches, operators should work on
opposite sides of pipe.

Test sleeve adhesion by gently pulling the
edge of the backing back to ensure that the
adhesive remains in place and is fully bonded
to the factory coating. The sleeve is well
bonded when the adhesive and coating remain
intimately contacted. If required to improve
bonding, additional heat should be applied to
the sleeve.
Visually inspect the installed sleeve for the
following:
• Sleeve is in full contact with the steel joint.
• Adhesive
fl ows beyond both sleeve edges.
• No cracks or holes in sleeve backing.

Wrap the sleeve loosely around the pipe,
ensuring the appropriate overlap.
Before fi nishing wrapping the sleeve:
1. heat the backing side of the underlap until
the backing starts to recover. Then use a roller
to secure the underlap to the pipe.
2. gently heat the green-yellow coloured adhe-
sive side of the closure seal until it appears
glossy.
