Covalence^® CSEM-F CASEAL (US)

Heat-shrinkable sleeve providing waterproof seal between casing & carrier pipe.
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.

CSEM-F/CASEAL (US) 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/CASEAL(US) assures an excellent bond between the sleeve and bare or pre-coated pipes.
The fiberglass reinforced woven and laminated backing gives the CSEM-F/CASEAL(US) 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/CASEAL(US) 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.
CSEM-F/CASEAL(US) is installed using standard gas torches. After pipe surface preparation and preheating, the support sheet is wrapped around the transition to be sealed followed by the heat-shrinkable sleeve. The sleeve is zipper-closed, forming a tube, and shrunk in place tightly fitting around the substrate. During recovery, the adhesive softens and flows to form a tight bond. The bond strength builds up during cool down and is fully retained after completion of the job.
