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 fi rmly 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.

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 fl ow 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
specifi c conditions. Preheat temperature
and profi le is dependant on project specifi c
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.
