Asphalt Adhesive Tape for the pipeline corrosion protection
Asphalt Adhesive Tape is Cold applied tape coating system for corrosion
protection of Oil, Gas, Petrochemical, Waste Water underground or overhead pipelines and waterproofing.
The Asphalt Adhesive Tape shall be applied after the primer by hand or with
a wrapping machine.
The specification of the Asphalt Adhesive Tape consists of three layers,
Backing:Special blend of stabilized polyethylene or PVC
Adhesive:Butyl rubber Bituminous Compound and Adhesion Promoting Resins
Interleaf: Anti-adhesive Film Treated with Silicone
_ Heavy duty butyl bitumen compound adhesive
_ Excellent adhesion to pipe and self
_ Flexibility provides extra protection at vulnerable areas
_ Excellent conformability and consistent uniform thickness
_ Easily applied with no special equipment
_ Compatible with common pipe coatings
_ Excellent resistance to cathodic disbonding
_ Resistant to UV
_ Can be applied over a wide temperature range
_ Good conformability and consistent uniform thickness
_ Cold applied

1) Steel pipe pretreatment
1.1 Keeping the pipe external surface clean and dry.Remove the dust, oil, welding slag, burrs,
grease and 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
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
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
3.4 After the primer dried, then wrapping the tape(It usually takes 3to 5 minutes.).
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.
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.
1. What is the payment terms.
