Fiberglass Reinforced Sleeve for Directional Drilling
FRDK is a high performance fiberglass reinforced sleeve specifically designed for girth weld corrosion protection on pipes used in directional drilling applications.
Construction: three-layer system
First layer: liquid epoxy, solvent-free, two-component
Second layer: high shear strength hot-melt adhesive
Third layer: radiation cross-linked, high density polyethylene, fiber reinforced composite structure.
Additional component: Wear Cone as extra protection against pull-through forces, of the same construction as the main sleeve.
The FRDK 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:
Superior cathodic disbondment and hot water immersion resistance.
Highly resistance to shear and peel forces induced by soil and thermal movement.
Easy to apply with minimal training
Superior abrasion resistance
Excellent adhesion performance
Preheat requirement for product installation
Application
---Oil & gas pipelines for directional drilling
---Water pipelines for directional drilling
---Compatible line coating: PE, FBE, Coal Tar
