CASEAL, Wrap-around Pipeline Heat Shrinkable Casing Seal Sleeve

CASEAL Wrap-around Pipeline Casing Seal

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

Product Description: CSEM-F/ CASEAL (US) casing/carrier step-down sealing.

• Construction: Two-layer system
• First layer: Visco-elastic mastic sealant.
• Second layer: Fiberglass reinforced, radiation cross-linked, polyethylene backing.

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.

Product Features/Benefits:

• Fiberglass reinforced backing provides high mechanical resistance as well as a high recovery capacity.
• 65% shrinkage ratio – conforms to high transitions reducing inventory & logistics costs.
• Resists a wide range of environmental and mechanical forces. Reliable, moisture-proof seal! Extremely tough.
• Specially formulated sealant ensures a strong bond & tight seal to virtually any substrate. Maintains its elasticity and sealing characteristics over a wide temperature range.
• Sealing adhesive automatically flows and repairs minor mechanical damages. "Self-healing effect". Saves time.
•  Zipper closure system allows simple & fast installation.
•  Usable also when service pipe is not concentric with the casing. Highly versatile.
•  No special equipment required makes installation fast and easy whiling keeping installation costs low.

CSEM-F/CASEAL(US) type products are available as a kit, containing:

• a Uni-sleeve (pre-cut sleeve with integrated zipper closure system)
• A support sheet
