Horizontal Directional Drilling Crossing Heat Shrinkable Sleeves reinforced with fiberglass

1.  Product Description :

Horizontal Directional Drilling Crossing Heat Shrinkable Sleeves  is a wrap-around heat shrinkable sleeve reinforced with fiberglass. It is designed to protect girth welds against corrosion and is the optimum joint protection for PE coated pipes used in directional drilling applications. The reinforcement gives the backing greater wear resistance.

The Heat Shrinkable Sleeve coating shall be capable of withstanding a maximum continuous operating temperature of 65ºC. Coating system shall withstand the Pull-through applications of Horizontal Directional Drilling (HDD) applications.

The Heat Shrinkable Sleeve shall provide mechanical protection to the epoxy layer and shall seal onto the epoxy layer and the adjacent line coating. It shall have the following minimum thickness:

Backing 1.85mm Backing fully free recovered 2.30mm 

Adhesive 1.2mm

Wear cone (incl. adhesive) 3.05mm

2. Benefits 

Highly resistant to shear and peel forces induced by soil and thermal movements.

It should offers abrasion and wear resistance at pull-through comparable to mill coatings.

Provision of appropriate wear cone which can protect leading edge of sleeve against pull-through forces.

Sleeve applied over wet epoxy---there are no curing or waiting times/formation of strong mechanical & chemical bonds.

Superior cathodic disbandment and hot water immersion resistance.

Pre-attached closure patch.

Low preheat requirements.
