Fiber reinforced, high expansion shrink sleeve for

sealing between casing and carrier


     CASEAL (CS) is used for casing/carrier step-down sealing. It is constructed in four layers.  The first layer is the visco-elastic, very aggressive mastic sealant.  The second layer is a radiation cross-linked polyethylene.  Third is a fiber mesh which gives excellent penetration resistance.  Fourth is another layer of a radiation cross-linked polyethylene.
     CASEAL (CS) 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 CASEAL(CS) assures an excellent bond between the sleeve and bare or pre-coated pipes.  The fiberglass reinforced woven and laminated backing gives the CASEAL(CS) sleeve a high mechanical resistance as well as a high recovery capacity. A zipper closing system allows a simple and fast installation.

     CASEAL(CS) is installed using standard gas torches. After pipe surface preparation and preheating, the heat shrinkable sleeve is wrapped around the transition to be sealed. 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.
