Canusa TBK-XL-65 Directional Drilling Kit is a high-performance system designed to protect welded joints on 2 and 3-layer PE, PP and FBE coated pipelines in directional drills. The system consists of two components: a heat-shrinkable sleeve which provides corrosion protection at the joint; and an ultraviolet light curable fiberglass protective overcoat. An optional epoxy primer is also available for superior corrosion protection in 3-layer systems. 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 disbondment and is designed for a wide range of operating temperatures.
Features & Benefits
Long Term Corrosion Protection: Canusa’s TBK-XL-65 - Directional Drilling Kit provides superior corrosion protection because of the protective shrink sleeve/epoxy primer combination. It uses Canusa GTS-65 as the corrosion protective sleeve. This corrosion protection sleeve provides excellent resistance to cathodic disbondment and excellent durability against abrasion and chemical attack. The result is effective, long-term protection against corrosion.
Superior Abrasion Resistance: Canusa’s TBK-XL-65 - Directional Drilling Kit utilizes an ultra-violet light curable fiberglass. This reinforcement provides excellent tensile and flexible strength, hardness and resistance to impact. The inherent performance properties
associated with the sleeve adhesive reduces damage of the coating during pipeline installation and provides excellent resistance to soil stresses and pipe movements.
Convenience: The fiberglass can be cured with a simple, hand-held, UV light. Epoxy primer is supplied in kits with all tools required to apply the primer and edge-coat. The convenient ready-to-mix epoxy packaging minimizes installation time and labor costs while promoting high production rates.
* Epoxy Kits Required. Uses the standard 170 mL Canusa E Primer Kit and assumes a 300 mm (12”) cutback, a 0.25 mm (10 mil) epoxy overcoat thickness, and a 0.15 mm (6 mil) mainline epoxy thickness covering (for 3-layer systems).
** UV FR is the ultra-violet curable fiberglass reinforcement for TBK sleeves. The table has the cut length required and number of TBKs possible per roll of UV FR for standard pipe sizes.
Canusa E Primer Properties:
Pot life @ 23°C (73°F): 20 minutes
Typical epoxy coated thickness: 4 - 6 mils
Shelf life @ 23°C, out of sunlight: 3 years
Example: For a directional drilling application of forty-eight (48) joints of 20” (610 mm) diameter coated pipeline with a total cutback length of 12” (300 mm) and operating up to a maximum of 65°C, you will need to order (at least) the following:
Corrosion protection sleeve: 48 @ GTS-65 610-450 BK
Epoxy for mainline: 48 x 4 = 192 @ E Primer 170 mL Kit
UV curable reinforcement: 48 ÷ 1 = 48 @ Canusa UV FR 950-10
1 .Denotes 3-layer system only.
2. Canusa UV FR is a self-extinguishing material that does not promote fire. It will give off CO and CO2, but no halogen gasses. Solidify unexposed surplus and dispose of together with processed material as cured plastic waste (in accordance with local and national regulations). Not classified as dangerous in the meaning of transport regulations.
