Introduction
PE heat shrinkable tape (sleeve) is composed of cross-linked
polyethylene back and special heat melt adhesive. Heat melt
adhesive has good bonding with PE back, steel pipe and Fusion
bonded epoxy (FBE layer). By heating PE back shrinks, adhesive
layer melts, and closely wraps around pipe joints, then it forms
together with FBE a firm and continuous anti-corrosion body. It is
resistant to corrosion, wear, impact, UV and aging, easier to be
operated.
Wraparound products
Application area:
It is mainly used for wrapping around pipe, anti-corrosion of kinds
of pipe joints, and repairing pipes.
For example: Oil and gas pipe, PU insulation pipe, 3PE/2PE FBE
coating steel pipeline joint.
