TBK Directional Drilling Kits by CANUSA-CPS

Multi-Layer sleeve system for directional drilling up to 80°C (176°F)
Product Description

Canusa's TBK - 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 three components: a primary heat-shrinkable sleeve which provides corrosion protection at the joint; a secondary heat-shrinkable sleeve which functions as a sacrificial wear cone; and a high-build epoxy top coat at the ends to provide 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 disbondment and is designed for a wide range of operating temperatures.

The Canusa Wrapid Sleeve™ Type TBK-60 is a one-piece wraparound sleeve designed for corrosion protection of buried and exposed steel pipelines operating up to 60 C (140 F). Wrapid Sleeve™ Type TBK-60 consists of a cross-linked polyolefin backing, coated with a technologically advanced protective adhesive which effectively bonds to steel substrates and common pipeline coatings including polyethylene and fusion bonded epoxy.

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 multilayer sleeves coated with a heat activated adhesive. 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. 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: 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.

Product Selection Guide

Selection Steps:

  1. Choose 2- or 3-layer TBK system based on mainline coating.
  2. Choose TBK system(s) based on expected pipe surface temperature during directional drilling and pipeline operating temperature.
  3. Choose ultimate TBK system based on pipeline performance requirements sand pipe size range. Product must be installed by pre-heating to the minimum installation temperature. Product must be installed by following the specific Product Installation Guide.

Typical Product Properties

Epoxy Primer Usage

* Epoxy Kit (required) uses the standard 170 mL Canusa E Primer. Kit and assumes a 30 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).

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
