Product Details


Pipeline Polyethylene 3ply Tape(T 4100 )
I Description
TheT400 series is Cold applied 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 bcking 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

IIFeatures:
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

IV.TAPE - INNERWRAP - CORROSION PROTECTION TAPE
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 tape must be fully compatible with the properties of the primer. The tape must be self-amalgamating between the layers and at the overlaps and must have a release paper or film.
 
V.TAPE ROLL SIZES
 
a) Hand application roll core diameter 41 mm
Tape length 15 m
Tape widths 50 and 100 mm
b) Application with hand wrapping machine, roll core diameter 41 mm
Tape length 15 m
Tape widths 50 and 100 mm
c) Application with hand wrapping machine, roll core diameter 78 mm
Tape length depending on pipe diameter
Tape widths 100 and 150 mm
d) Application with motor driven wrapping machine, roll core diameter 78 mm
Tape length depending on pipe diameter
Tape widths 100 and 150 mm
 
VI.TAPE - OUTERWRAP - MECHANICAL PROTECTION TAPE
 
Two-ply plastics tape consisting of a stabilized high density polyethylene backing with plastic butyl rubber on one side. The outer wrap tape must be fully compatible with the properties of the inner wrap. The outer wrap must fully self-amalgamate with the inner wrap tape at contact areas.
In order to avoid delaminating between carrier film and butyl rubber, tape should contain co-extruded intermediate layers.
 
VII.TAPE SYSTEM
Tape system shall comply with EN 12068 (stress-class C-50) and DIN 30672 (stress-class C-50).

WRAPPING MACHINES
 
To apply hand rolls with a 41 mm core diameter. - as per a), the hand wrapping machines must be able to automatically remove the release film from the three - ply tape during application, maintain constant overlap and tape tension.
 
To apply rolls with 78 mm plastics roll core diameter - as per c) and d) a sufficient quantity of wrapping machines must be quoted. These machines must be able to automatically remove the release film from the inner wrap tape, maintain constant overlap and give the necessary tape tension.
