Pipe wrap outer tape similar polyken white tape

  Pipe Wrap outer tape similar polyken white tape

  Pipe wrap outer tape similar polyken white tape  systerm for corrosion

protection of oil, gas, petrochemical, waste water underground and  overhead pipelines.

the inner layer tape shall be applied after the primer and before the outer layer tape .

Pipe wrap outer tape similar polyken white tape is with a stabilized

polyethylene carrier film, coated on one sides with a permanently plastic synthetic

compound on a butyl rubber base. The highly stable and supple carrier film

guarantees a high degree of protection from mechanical damage.

 Structure:    

  Wrapping materials for underground pipes(Pipe Wrap Tape) consists of two layers:

 adhensive layer and film backing

 A:adhensive layer: butyl rubber

 B:film backing: special  blend of stabilized polyethylene

Feature:

 Excellent adhension to pipe and itself

1:Resistant to UV

2:Can be applied over a wide temperature range

3:Good conformbility and consistant uniform thickness

4:Easily applied with no special equipment

5:Compatble with common pipe coating

6:Excellent  resistant to cathodic disbonding

7:Meet  ASTM D 1000 standards

8:Cold applied

 Application

Prepare surfaces by eradicating all loose scale, rust or other foreign

matter by grit blasting or wire brush. The surface must be clean, dry and free of grease.

Peel back strip and apply tacky side of the tape to the surface and apply pressure.

Apply the tape spirally with sufficient tension to make it conform.

Remove interleaving as wrapping proceeds. Overlap each turn by at least 1” or 55%.

(Note: when proper surface prep is not achievable or when applying

to pitted pipe, apply a thin film of Butyl Pipe Primer to all surfaces

to be wrapped and allow to dry). (Over width silicone paper prevents

product contamination during site handling and storage). 

Wrapping materials for underground pipes(pipe wrap tape)  is used as the base

material which is coated by the liquid butyl rubber film, both of which are

pressed and compounded. The film of protective tape is thicker and higher in intensity,

color is white.

Wrapping materials for underground pipes(pipe wrap tape) will protect the pipe

and its anti-Corrosion Tape surface from damages.

Xunda wrap have been specially developed for high-quality, onsite corrosion

protection for joints, in cases where the pipeline has already been installed.

The material is easy, safe and quick to apply on welded joints,

bends and other complicated shapes.
