Ensure that the pipe is dry before cleaning.
Thoroughly clean the weld area with a sand or
grit blaster to “near white metal” SIS Sa 2½ or
equivalent. Using a grinder with a grind disk
with roughness rating of 40-60, ensure that
the PP mainline coating edges are beveled to
15° from the horizontal and that the adjacent
PP pipe coating is cleaned, exposing fresh
PP, to a distance of 25mm beyond the sleeve
width.

Place the underlap of the sleeve onto the joint,
centering the sleeve such that the sleeve
overlap is positioned at either the 10 or 2
o’clock position. Press the underlap firmly into
place and use a roller to work out any trapped
air. Feed the remaining length of sleeve under
the pipe.
Optional Heat Shields can be used during the
sleeve application. After wrapping the sleeve
around the pipe, the heat shields can be
wrapped adjacent to the sleeve to protect the
mainline coating during shrink down.
Equipment List

GTS-PE Global Transmission Sleeves are
shipped pre-cut with a preattached closure.
Bulk quantities are also available. The joint
completion system uses liquid epoxy on
bare steel cutback. The GTS-PE sleeves are
packaged in PE bags that are only to be opened
prior to the application of the product.

Liquid Epoxy Application
Apply mixed epoxy to a minimum uniform
thickness of 6 mils (150 microns) on all
exposed bare metal plus FBE toe only, using
the applicator pads as supplied or an approved
tool.
11
Check the temperature to ensure the preheat
has been obtained on the entire pipe circum-
ference. This preheat will substantially cure the
epoxy and ensure proper flow and bonding of
the sleeve adhesive. Ensure that the epoxy is
dry to the touch prior to sleeve installation.
Sleeve InstallationPre-Heat
Preheat the epoxy to a minimum of 130°C
using the appropriate sized induction coil. While
induction heating is highly recommended, in
certain cases, propane torches may be used if
proven to provide acceptable results in project
specific conditions. Preheat temperature
and profile is dependant on project specific
conditions, and must be determined prior to
the start of the project.

Liquid Epoxy
Follow the preparation, mixing and applications
instructions provided with the supplied Canusa
Liquid Epoxy Pack. For bulk quantities, mix
the epoxy cure with epoxy base (see Liquid
Epoxy Product data sheet for mixing ratio). Stir
for a minimum of 1 minute to assure uniform
mixture.

Positional Markings
Measure and mark the width of the GTS-PE
sleeve across the joint. Also, adjust the induc-
tion coil’s heating area to the width of the
GTS-PE sleeve. The induction coil heating
width shall be approximately 25 to 75 mm
wider than the supplied GTS-PE sleeve width.

Wipe clean or air blast the steel and pipe
coating to remove foreign contaminants.
Pre-Warm
Using the appropriate sized induction coil or
propane torch, pre-warm the steel area to
50-65°C. Using a temperature measuring
device, ensure that the correct temperature is
reached on the steel.

snow, dust or other adverse environmen-
tal elements. Avoid prolonged storage at
temperatures above 35°C (95°F) or below
-20°C (-4°F). Product installation should be
done in accordance with local health and
safety regulations.

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
firmly rolling the closure with long horizontal
strokes from the weld outwards.
With the green-yellow coloured adhesive side
facing down, firmly 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 flame intensity.
14 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).
Onshore and Offshore Guidelines
16
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 flows beyond both sleeve edges.
• No cracks or holes in sleeve backing.
Quality Check - Adhesion Test Inspection
13
Wrap the sleeve loosely around the pipe,
ensuring the appropriate overlap.
Before finishing 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.
