TheT400 series Polyethylene 3ply Tape for Pipelines
is Cold applied pipe anticorrosion tape coating system for corrosion protection
of Oil, Gas, Petrochemical, and Waste Water underground or overhead
pipelines. It is a three-ply cold applied tape with stabilised polyethylene backing
and butyl rubber adhesive layers on both sides.It is also used as inner-layer
tape. It shall be applied by hand or with a wrapping machine
Excellent bonding between adhesive and carrier film via co-extruded intermediate layer.
Mechanically highly resistant tape system.
Practically impermeable to water vapour and oxygen.
Resistant to soil bacterial and soil electrolyte.
Compatible with coating from PE,PP,FBE,PU,CTE and Bitumen and ext… .
A Total Coating System with:
High adhesion and shear resistance
Resistance to corrosion disbondment
High electrical resistance
High dielectric strength
High corrosion protection for steel substrates
Asymmetrically structured three-ply plastics tape consisting of a stabilized polyethylene backing with
plastic butyl rubber on both sides. The consistency of the butyl rubber on the one side facing the pipe
surface should be formulated in such a way that, under tension, it flows on uneven steel surfaces. To
facilitate correct application this butyl layer should be of a black color. The grey butyl layer of the tape
must face the steel and this should always be the thicker layer of butyl rubber.
In order to avoid delaminating tape must contain co-extruded intermediate layers.
The anticorrosion tape must be fully compatible with the properties of the primer. The anticorrosion tape must be self-amalgamating
between the layers and at the overlaps and must have a release paper or film.
