Quick Overview
    Covalence® DHEC is a District Heating End Cap for sealing the pipe ends of pre-insulated pipes carrying fluids at various operating temperatures up to 120°C and occasionally with a peak temperature up to 140°C. DHEC is a molded part with different outlet diameters on each end to accommodate the diameters on both casing and service pipe. DHEC Single is designed for pre-insulated pipes having one service pipe. The elastomeric adhesive is specially designed for high temperature performance. The uncoated edges prevent the sleeve from slipping off the casing pipe during installation. The installation is carried out directly on the prepared and preheated pipe surface, DHEC is slid over service and casing pipe and positioned in place. The DHEC is then heated with a regular gas torch. The high shrink ratio backing shrinks and forms a tight fit onto the pipe and casing. During recovery, the adhesive softens and flows to form a waterproof seal. Features of the product include high shrink ratio backing offering optimum conformability to transitions and variations, one product covering several different pipe sizes, high performance against water ingress, tubular mold system (just “slide over & shrink”), and no special equipment required. Benefits of the product include that it easily adapts to dimensional variations and pipe ovality, it reduces inventory costs and simplifies logistics, its thermal insulation remains functional, and its easy and fast installation minimizes costs.
