Description
DENSOPOL 60HT – HEAVY DUTY PVC/BITUMEN FABRIC-REINFORCED TAPE
A synthetic fabric reinforcement coated with rubber bitumen adhesive compound and backed with a conformable PVC film. Due to its great flexibility Densopol 60 HT is used for wrapping small to medium diameter pipes, welded joints, bends and fittings whereas Densopol 80 HT is used on larger diameter pipes.
Densopol 60 & 60 HT is a cold applied, synthetic fabric reinforcement coated with rubber bitumen adhesive and backed with a PVC film.
The extreme toughness is due to the combination of the heavy duty PVC backing and the fabric reinforcement in the bituminous adhesive compound.
Uses
For the anti-corrosion protection of buried or immersed pipes and fittings and protection & refurbishment of steel and ductile pipes, joints, tie rods, bends and fittings in tropical climates. The tapes can be applied by hand or machine to weld joints, bends, bare pipe lengths and pipe fittings.
Composition
Synthetic fiber fabric impregnated and coated with polymer modified bitumen compound laminated to PVC sheeting. The compound surface is protected by a plastic film interleaving which is discarded during application.
Features
- Applied to marginally prepared surfaces (SSPC SP 2-3).
- Cold applied.
- Good comformability.
- Good impact resistance.
- Excellent adhesion to pipe and self.
- Excellent resistance to cathodic disbonding.
- Compatible with common pipe coatings.
Characteristics
- Exceptionally resistant to shear.
- Resistant to damage by back fill.
- Suitable for tropical climates.
Application
Prepare surfaces by removing all loose scale, rust or other foreign matter by wire brush. Surface must be clean, dry and free of grease. Apply thin film of Denso Primer D to all surfaces to be protected and allow to dry. Peel back interleaving and apply adhesive side of the tape to the primed surface and press down. Apply the tape spirally with enough tension to make it conform. Remove interleaving as wrapping proceeds. Overlap each turn by at least 1″ (25 mm) or 55% to achieve double thickness. Irregular surfaces such as valves, flanges, etc. may require the use of Densyl Mastic or Denso Profiling Mastic. Refer to the product sheets for these specific products for information on application and selection.
Testing
Ensure the application has:
· sufficient tension,
· no creases or folds, and
· sufficient overlap.
Availability
Densopol 60 HT is available in 10 or 30 metre rolls in widths from 50 mm to 300 mm.
