Product Description
Polymer Bitumen Tape for the flange valve anti corrosion
I. Description
Polymer bitumen tape is a cold applied coating designed to provide protection against corrosion and electrolysis on below grade metal substrates.The anti corrosion bituminous rubber compound provide self sealed joints at longitudinal and end of roll overlaps, and is highly resistant to cathodic elasticity. The unique extruded PVC or PE carrier is engineered for toughness, conformability and cotrolled elasticity.
A medium duty tape ,designed to protect small and medium diameter pipes, welded joints, bens and fittings.The tough yet conformable PVC or PE backing provides excellent resistance to damage during handling and backfilling .
The bitumen tape is cold applied Adhesive waterproof membrane . Designed for internal and external tanking to prevent ingress of water into buildings and to protect building structures, culverts etc,from the effet of chloride ,sulphates etc in ground water and soil/
For the anti Corrosion Protection of buried or immersed pipes and fittings.Suitalbe for machine or hand application.
II .Structure
The specification of the tape consists of three layers,a thick polymer Bitumen Adhesive laminated to a tough plasticised PVC or PE backing. The adhesive layer is protected by an interleaving ,whick is removed during application.
Backing:Special blend of stabilized polyolefines
Adhesive:Butyl rubber Bituminous Compound and Adhesion Promoting Resins
Interleaf: Anti-adhesive Film Treated with Silicone

1) Steel pipe pretreatment
1.1 Keeping the pipe external surface clean and dry.Remove the dust, oil, welding slag, burrs,
grease an dirt on pipe surface.
1.2 Pipe surface prepared up-to a level of Sa 2 or 2 ½ or St 2/st by sand blasting.
1.3 After the precleaning operations, the pipe surface not smoothwhich may sharp the pipe coating
should be burnished , the abrasive dust attached on the pipe surface should also be
cleaned clearly.
1.4 If flash rusting occurs, the surfaces must be re-cleaned by blasting as above.
2) Coating &Wrapping application
2.1 Coating &wrapping application consist of primer application, inner tape coating ,outer tape
coating .
2.2 weather condition
2.2.1 When the wind&sand was strongly, when the sand and dust covered on the surface of pipe,
primer , tape etc., should not be brushing primer and wrapping the tape if there is
no reliable preventive measures.
2.2.2 When air humidity is greater than 80%,or when the pipe surface is wet from any precipitation,
should not be brushing primer and wrapping tape.
3) Brushing primer
3.1 The brushing time should be control within 6 hours between the pipe surface treatment and
brush primer.During brush primer, pipe surface should be free from damp and
pollution. If the pipe surface rust return, should be re-pre-cleaned.
3.2 The primer should be mixed evenly in the container before brushing.
3.3 The primer should be applied uniformly, without any sags, floods, runs, drips, bare spot and
over spray, such as leakage brush, clot, streaming. The primer coat DFT shall not be less
than 25-50micron (1-2mils)
3.4 After the primer dried, then wrapping the tape(It usually takes 3to 5 minutes.).
3.5 Consumption:
machine applicationapprox. 0,1 litre/m²
hand applicationapprox. 0,2 litre/m²
4) Wrap tape application
4.1 Wrap tape application consists of hand application and machine application.
4.2 The tape applied temperature must be above 5 degrees,the coating construction temperature
shall be more than -5 degrees as better .
4.3 The tape shall be spirally applied ,minimum overlap shall not be less than 50%.
4.4 When a new roll of tape started ,the ends shall be located to ensure the continuity of wrap tape
using the same method of application.
4.5 Outer tape applied method is the same as above.
5.Cutbacks
Cutbacks shall be a minimum 6inches(150mm) from the ends of each pipe.The cutbacks may be
tapered or straight edge for the total thickness of the coating.
