heat shrinkable wraparound sleeve
　
Product Description
CEP-4 is a field applied heat shrinkable wraparound sleeve designed for field joint corrosion protection. The inner layer is two-components epoxy primer which coated on steel pipe; the middle layer is hot melt adhesive; the outer layer is the modified radiation crosslinked polyethylene backing; the closure patch.
Features and Benefits
CEP-4 is a wraparound sleeve with a closure patch. The shrinkable ratio is ≥15%. It is mainly applied to pipe joint corrosion protection and the prosthesisses of wide range damage.
Excellent coating compatibility
CEP-4 can be applied to a wide range of pipe coating including 2 layers polyethylene, 3 layers polyethylene, 3 layers polypropylene, fusion bonded epoxy, insulated jacket, coal tar primer. It can be used for corrosion protection of pipe joint and corrosion seal of reducer or valve. The effectiveness and excellence have been approved by many pipeline projects.
Rapid installation
The adoption of new materials and updated technology further predigests the installation. The liquid epoxy primer provided by XIPU can be used at a low preheating temperature which between 55oC~60oC, quick, reliable field installation is easy to accomplish. The most recent innovation is the “adhesiveless agglutinated closure patch”. It has further improved the installation quality of CEP-4 at job site. It has facilitated of heat melt adhesive, improved the lap shear strength.
Long term corrosion protection
CEP-4 provides excellent resistance to soil creeping stresses and chemical attach. With the closure patch, product’s structure can guarantee more effective waterproof when it used on the buried and off-sea pipeline. The high performance crosslinked backing in combination with adhesive, can resists adverse environments.
