Product Description
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.
