CANUSA TBK -
Directional Drilling Kit
Multilayer sleeve
system for directional drilling
Product Description
CANUSA's TBK - Directional Drilling Kit is a high
performance system designed to protect welded joints on 3 layer PE and FBE coated
pipelines in directional drills. The system consists of three components - an epoxy, a
primary heat-shrinkable sleeve which provides corrosion protection at the joint; and a
secondary heat-shrinkable sleeve which functions as a sacrificial wear cone. A high-build
epoxy top coat at the ends provides additional protection to the system. The system
provides effective protection against abrasion and wear forces that occur during the
pull-through operation. The system is fully compatible with cathodic protection systems,
resists cathodic disbandment and is designed for operating temperatures up to 50°C
(122°F).

| Features & Benefits
Long-Term Corrosion Protection
CANUSA's TBK - Directional Drilling Kit provides superior
corrosion protection because of the epoxy primer and the protective shrink sleeve. This
combination provides excellent resistance to cathodic disbandment and excellent durability
against abrasion and chemical attack. The result is effective, long-term protection
against corrosion.
Superior Abrasion Resistance
CANUSA's TBK - Directional Drilling Kit utilizes multi
layer sleeves coated with a high shear hot melt type adhesive. The inherent high shear
strength of the adhesive reduces damage of the coating during pipeline installation and
provides excellent resistance to soil stresses and pipe movements. The narrow, epoxy
coated sacrificial sleeve is applied to the leading edge of the primary sleeve. The
hardened epoxy topcoat provides the additional abrasion and wear resistance to withstand
the forces during directional drilling.

Convenient Epoxy Kit
E-Primer epoxy primer is supplied in kits with all tools required to
apply this system. The convenient ready-to-mix epoxy packaging minimizes installation time
and labor costs while promoting high production rates.
Epoxy Primer Application Guidelines
- Apply epoxy to steel substrate and only 10 mm onto adjacent
coating.
- Apply epoxy thoroughly to entire sacrificial sleeve, 50 mm
onto coating, and 50 mm onto first sleeve behind the sacrificial sleeve.
- Apply epoxy thoroughly to trailing edge of first sleeve, 50
mm onto sleeve, and 50 mm onto coating.
