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
fi rmly 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 for a 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.

GTS-80 Global Transmission Sleeves are
shipped pre-cut with a pre-attached clo-
sure. Bulk quantities are also available.
The adhesive is protected from contami-
nation by an inner liner.
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.
Preheat the epoxy to a temperature of
110°C and the abraded mainline coat-
ing to be covered by the sleeve to a
minimum of 100°C with the appropriate
propane torch, induction heating or infra-
red heating equipment.
Do not use an
intense fl ame on the mainline coating.
If
a fi lm develops on the mainline coating
because of preheat, use a surface abra-
sion tool to remove it.
