CEP-4 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.
Apply with the primer at "wet state"
The heat shrinkable sleeve is applied on the "wet state" of primer allowing formation of strong mechanical and chemical bonds, allows fast application, combined with high performance.
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 40 ºC~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.
