Product Description
DIRAX Horizontal Direct Drilling heat shrink sleeve for pipes
Product description:Dasheng DIRAX system is a wrap-around heat-shrinkable sleeve reinforced with fiberglass similar with Raychem DIRAX, it is designed to protect girth welds against corrosion and is the optimum joint protection for PE and FBE coated pipes used in Horizontal Directional Drilling (HDD-Pull Through)
applications. The reinforcement gives the backing greater wear resistance.
Construction: Three-layer system
* First layer: Liquid epoxy, solvent-free two-component.
* Second layer: High shear strength copolymer adhesive.
* Third layer: Thick, fiberglass reinforced, radiation cross-linked polyethylene.
* Additional component: Wear Cone as extra protection against pull- through forces, of the same construction as the main sleeve.During installation, the epoxy is applied to the prepared pipe surface and the heat-shrinkable 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 & 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.
Features:
* Highly resistant to shear and peel forces induced by soil and thermal movements.
* DIRAX offers abrasion and wear resistance at pull-through comparable to mill coatings.
* Wear cone protects 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 disbondment and hot water immersion resistance.
* Independent closure patch.
* Low preheat requirements.
Benefits:
· The DIRAX is tough! · Provides a monolithic coating system.
· Provides additional strength and security---increases reliability.
· Allows fast application---saves time! Ensures high performance!
· Offers the optimum barrier protection against corrosion.
· Allows fast and easy application.
· Makes installation faster and saves time.| Product selection guide |
