Covalence® CSEM-F

Quick Overview

CSEM-F is a heat-shrinkable, wrap-around sleeve with a very high shrink ratio, specially developed for casing/service pipe sealing. The special adhesive inside the thick-wall CSEM-F assures an excellent bond between the sleeve and bare or precoated pipes. The fiberglass reinforced woven and laminated backing gives the CSEM-F sleeve a high mechanical resistance as well as a high recovery capacity. A zipper closing system allows a simple and fast installation. In addition to the CSEM-F sleeve, a support sheet is supplied which provides a smooth step-down in the transition area to ensure a tight closure and enhances the mechanical strength. Construction: Two-layer system. First layer: Visco-elastic mastic sealant. Second layer: Fiberglass reinforced, radiation cross-linked, polyethylene backing. Additional kit component: Non-shrinkable, polypropylene support sheet. Optional is a high shear hotmelt is added on the casing pipe side of the sleeve to increase the anchoring on the casing pipe for harsh soil conditions. Features of the product include: fiberglass reinforced backing, 65% shrinkage ratio – conforms to high transitions, resists a wide range of environmental and mechanical forces, sealing adhesive automatically flows and repairs minor mechanical damages, usable also when service pipe is not concentric with the casing, no special equipment required. Benefits of the product include: provides high mechanical resistance, provides a high recovery capacity, reduces inventory & logistics costs, reliable, moisture-proof seal that is extremely tough, ensures a strong bond & tight seal to virtually any substrate, maintains its elasticity and sealing characteristics over a wide temperature range, the product exhibits a "self-healing effect" that saves time, it i highly versatile, and it makes installation fast and easy which keeps installation costs low.
