III Technical datas
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.

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.

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.
