Ensure that the mainline coating edges
are beveled to 30°. If there is the pres-
ence of oil, grease, or other surface
contaminants; clean the exposed steel
and adjacent pipe coating with a solvent
cleanser.
Apply mixed epoxy to a minimum uni-
form thickness of 4 mils on all exposed
bare metal plus 10 mm (0.5”) onto the
adjacent pipe coating.
Centre the sleeve over the joint so that
the sleeve overlaps between the 10 and
2 o’clock positions. Press the underlap
firmly into place. Remove the remaining
release liner.

Follow the Preparation, Mixing and
Application instructions provided with
the supplied Canusa Epoxy Pack. For
bulk quantities: mix the primer cure with
the primer base (4 parts base to 1 part
cure by volume). Stir fora minimum of 30
seconds to assure uniform mixture.
Partially remove the release liner and
gently heat the underlap approximately
150 mm (6”) from the edge.
Global Transmission Sleeve
Propane tank, hose, torch & regulator;
Appropriate tools for surface abrasion;
Epoxy application accessories & wet
film thickness gauge; Knife, roller, rags
& Canusa approved solvent cleanser;
Digital thermometer with suitable probe;
Standard safety equipment: gloves, gog-
gles, hard hat, etc.
Using a dry, grease and lint-free cloth,
wipe clean or air blast the steel and
coated areas to remove foreign materi-
als. If necessary, provide additional heat
to ensure the surface temperature is
40-50°C (104-120°F).
Check the temperature to ensure the
preheat has been obtained on the
entire pipe circumference. This preheat
will substantially cure the epoxy and
ensure proper flow and bonding of the
sleeve adhesive. Ensure that the epoxy
primer is dry to the touch prior to sleeve
installation.

GTS-65 Global Transmission Sleeves
are shipped pre-cut with a pre-attached
closure. Bulk quantities are also avail-
able. The sleeve adhesive is protected
from contamination by an inner liner. The
joint completion system may also use an
epoxy primer.
Warm the joint area to 40-50°C (100-
120°F) before grit blasting. Thoroughly
clean the weld area with a sand or grit
blaster to “near white metal” SIS Sa
2½ or equivalent. Abrade the mainline
coating adjacent to the weld area to a
distance 50 mm (2”) beyond the sleeve
width.
Pre-heat the epoxy and the abraded
coating to 90°C ± 5° (195°F ± 10°) with
the appropriate propane torch. This will
substantially cure the epoxy and ensure
proper flow and bonding of the sleeve
adhesive. Do not use an intense flame
on the mainline coating. If a film devel-
ops on the mainline coating because of
preheat, use a surface abrasion tool to
remove it.

After shrinking is complete, allow the sleeve to cool for 2 hours prior to lowering and
backfilling. To prevent damage to the sleeve, use selected backfill material, (no sharp
stones or large particles) otherwise an extruded polyethylene mesh or other suitable
shield should be used.

Wrap the sleeve loosely around the pipe,
ensuring the appropriate overlap. Gently
heat the backing of the underlap and the
adhesive side of the overlap.
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.
Press the closure firmly into place. Gently heat the closure and pat it down
with a gloved hand. Repeating this pro-
cedure, move from one side to the other.
Smooth any wrinkles by gently working
them outward from the centre ofthe clo-
sure with a roller.
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.
While the sleeve is still hot and soft, use
a hand roller to gently roll the sleeve sur-
face and push any trapped air up and out
of the sleeve, as shown above. Continue
the procedure by also firmly rolling the
closure with long horizontal strokes from
the weld outwards.
Epoxy required for 300 mm / 12” cutback.
For other cutbacks, divide by 12 and multiply by new
cutback in inches.
Example:
200 mm (8”) cutback on 610 mm diameter pipe
base: 88 ml x 8/12 = 60 ml base
cure: 22 ml x 8/12 = 15 ml cure
300 mm / 12” cutback and
0.15 mm / 0.006” epoxy thickness
Shrinking has been completed when the
adhesive begins to ooze at the sleeve
edges all around the circumference.
Finish shrinking the sleeve with long hor-
izontal strokes over the entire surface to
ensure a uniform bond.
Visually inspect the installed sleeve for
the following:
• Sleeve is in full contact with the steel
joint.
• Adhesive flows beyond both sleeve
edges.
• No cracks or holes in sleeve backing.
