TBK

Advanced girth-weld protection

for pipes used in directionally

drilled applications

The TBK Directional Drilling system is specically designed to

protect welded joints on PE, FBE and HPCC coated pipelines in

directional drilling applications. In addition to providing effective

protection against pull-through forces that occur during the

directional drilling operation, Canusa’s TBK systems provide

superior corrosion protection at pipeline weld joints. The product

range includes TBK-65, TBK-80 and TBK-PE, which are each

designed to meet specifict

application conditions and operating

requirements

Multi-Layers of Protection

 Force-cured liquid epoxy applied to steel, if required, for maximum

corrosion protection

  Primary sleeve composed of high shear strength adhesive, a

protective heat shrinkable backing, and a pre-attached

closure patch

  Sacrificial sleeve incorporated to protect the leading edge of the

underlying primary sleeve during pull-through operation

  Epoxy overcoat applied at the leading and trailing ends of the

joint coating to provide additional protection to the system during

directional drilling

Superior Gouge and Abrasion Resistance

  Designed to mitigate the effect of forces associated with directional

drilling

  Highly resistant to the effect of soil stresses and pipe movements

 Canusa’s Wrapid Shield™ XL, Wrapid Shield™ XLE and HBE-DX

products are provided as alternatives for added mechanical

protection as an overcoat

Unique Adhesive Technology

  Allows for lower installation pre-heat temperatures

and superior bonding to mainline coating

 Adhesive has been formulated to bond directly to the

mainline coating; epoxy (if required) is applied to the

steel only

  Lower pre-heat temperature means less time heating resulting in

application time and cost
