HLD T900 PVC pipe wrapping tape
1.Product Description
PVC adhesive tape is ‘All Weather’ self-adhesive PVC tape.
It is for the protection of steel and ductile pipes, welded joints, bends and fittings and similar structures from corrosion above ground or buried or immersed.
The tough PVC backing is selected to suit different requirements of soil conditions and pipe
diameters.
PVC bitumen tape can be applied by most operators with the minimal amount of training on
site/ in situ or in a workshop.
2.Composition
The self adhesive PVC tape is composed of tough PVC backing and heavy duty rubber
modified bitumen compound or Butyl rubber.
The tough and flexible PVC backing has high resistance to alkali and acid, excellent
mechanical resistance, ensures exception resistance to damage by impact or poor backfill
and in aggressive ground condition.
The polymer modified bitumen compound is thick and has high shear resistance and
cathodic disbondment.
The bitumen compound layer is protected by an interleaving, wider than the tape, which is
removed/discarded during application.
3.Product Usage:
PVC Bitumen Tape is easy to apply with no special tools or equipment.
Being tough flexible PVC tape, it is suitable for different pipe diameters , particularly for
protection of medium and large diameter pipes, weld joints, bends and fittings, above or
under ground.
There are two regular usage:
a) PVC bitumen tape used as single corrosion protection layer on primed steel pipe surface.
b) Used as PVC protective outer layer in multi-layer coating system.
