denso tape wrapping coating materials PE outer tape

Product Description

    denso tape wrapping coating materials PE outer tape

is  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 .

  similar denso tape wrapping coating materials PE outer tape for gas oil water pipe 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:    

  similar denso tape wrapping coating materials PE outer tape

for gas oil water pipe  consists of two layers:

 adhensive layer and film backing

 A:adhensive layer: butyl rubber

 B:film backing: special  blend of stabilized polyethylene

Feature:

   denso tape wrapping coating materials PE outer tape

 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

   denso tape wrapping coating materials PE outer tape

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.

Our Factory:

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.
