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.

Global Transmission Sleeve

Propane tank, hose, torch & regulator; 
Appropriate tools for surface abrasion; 
Epoxy application accessories & wet 
fi lm 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 fl ow 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 fl ow and bonding of the sleeve 
adhesive. 

Do not use an intense fl ame 

on the mainline coating.

 If a fi lm devel-

ops on the mainline coating because of 
preheat, use a surface abrasion tool to 
remove it.
