Covalence® Dirax HDD

Quick Overview

The DIRAX system is a wrap-around heatshrinkable sleeve reinforced with fiberglass. DIRAX 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. Features include: 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,pre-attached closure patch, and low preheat requirements. Benefits include: tough and durable, provides a monolithic coating system, provides additional strength and security thereby increasing reliability, it allows fast application thereby saving time and ensuring high performance, it offers the optimum barrier protection against corrosion, it allows fast and easy application, and it makes installation faster and saves time. Covalence® DIRAX type products are available as a kit, containing a wear cone (also pre-cut with pre-attached closure patch). DIRAX is installed with S1301-M 2-component epoxy primer which has to be ordered separately.
