DIRAX

Fiber reinforced shrink sleeve for road bores,

directional drilling and thrust bore applications.

 

     DIRAX is a three-layer shrink sleeve system.  The first layer is a liquid epoxy, solvent-free two-component.  The second layer is a high shear strength copolymer adhesive.  The third layer is a thick, fiberglass reinforced, radiation cross-linked polyethylene shrink sleeve.  An additional component is also used: the wear cone is extra protection against pull-through forces; of the same construction as the main shrink sleeve sleeve.
     The DIRAX system is a wrap-around heat-shrinkable sleeve reinforced with fiberglass.   DIRAX is designed to protect girth welds against corrosion and is the optimum joint protection for PE, FBE, Dual Layer and Powercrete coated pipes used in directional drilling applications. The reinforcement gives the backing greater wear and penetration resistance.  During installation, the epoxy is applied to the prepared pipe surface and the heat shrink sleeve is immediately wrapped around the joint over the wet epoxy.  Heat is then applied to the sleeve, which shrinks to form a tight fit around the joint. While curing, the epoxy forms strong mechanical and chemical bonds to the pipe surface and to the copolymer adhesive layer. The radiation cross-linked outer layer forms a tough barrier against mechanical damage and moisture transmission. A wear cone is then applied over the leading edge of the sleeve.
