CNP HDD system is Horizontal Directional Drilling wrap-around heat shrink sleeve
CNP HDD system is Horizontal Directional Drilling wrap-around heat shrink sleeve reinforced with fiberglass.HDD is desighed to protect girth welds anti-corrosion and is the ideal joint protection for PE coated pipes used in directional drilling applications.The reinforcement offers abrasion and wear resistance at pull-through.
Construction
First layer: Liquid epoxy, solvent-free two-component.
Second layer: High shear strength hot melt adhesive.
Third layer: Fiberglass reinforced radiation cross-linked polyethylene.
Features & Benefits
● CNP HDD is a wraparound sleeve with a separate closure
● Reinforcement backing gives optimum abrasion and mechanical resistance.
● Dimpled backing provides a “permanent change” indicator for application when heat.
● Highly shear resistance and peel forces by soil and thermal movements.
