980-20 polyethylene butyl rubber inner tape wrapping for gas pipe
Product Description
980-20 polyethylene butyl rubber inner tape wrapping for gas pipe
The Xunda anti-corrosion tape T100, mechanical protection tape T200 is a multilayer system used for the
corrosion protection of oil ,gas ,and water underground or aboveground steel pipeline.
T100 &T200 consist of two layers, the butyl rubber Adhesive laminated on the polyethylene film backing.
The T100 can be used as inner tape, T200 can be used as outer tape.
Xunda liquid adhesive can be used as primer for this system.
The liquid adhesive represent an anti-corrosion layer and provide a uniformly smooth contact surface
to promote high adhesion of the coating system to the pipe.
The anti-corrosion tape assures a high bond to the primed surface with excellent conformability.
The mechanical protection tape achieves a complete bond to the anti-corrosion tape.
The system can be applied by hand or with a wrapping machine.
Cold applied without special equipment.
Resistant to soil stress
Excellent adhesion to primed pipe and itself.
Can be applied over a wide temperature range.
Good conformability and consistent uniform thickness.
Compatible with common pipe coatings.
Excellent resistance to cathodic disbondment.
Long term in-ground performance
Meets ASTM D 1000 ,EN 12068,AWWA C214,
C209 ,DIN 30672 and other international standards.

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 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.
We manufacture polyethylene coating by utilizing butyl based elastomeric adhesives, Polyethylene films and liquid adhesives for Corrosion Protection of steel pipes.
Our company provides corrosion protection with the inherent chemicals of polyethylene and butyl adhesive for water resistance and oxygen penetration. Oxygen and Water are prevented from reaching the metal substrate. They are the necessary and sufficient conditions for corrosion.
We manufacture conventional and special polyethylene, polypropylene and polymeric alloy and coating systems for pipe corrosion protection. We manufacture PE coating systems for the applications of new pipe construction, rehabilitation and reconditioning. Our products are ISO9001 approved and are in accordance with other good manufacturing and technical standards and norms in the energy and pipeline industry. Coating systems have a broad range of temperature and shearing resistant properties to meet the requirements of pipeline end-users.
