Polyethylene wrapping coating tape

Polyethylene wrapping coating tape,the following is the mainly anti corrosion pipe coating tape, Inner wrap and outer wrap:

1)Polyethylene inner wrapping coating tape:
Thickness should be minimum 0.305 mm (0.012"), with self-adhesive compound thickness 0.203 mm
(0.008") minimum.
Interleaf in rolls supplied shall be double sided release coated paper or polymer preferably with extra
width for roll

Characteristics of tape:
- Elongation : 250%
- Tensile strength : 7 N/mm2
- Tear resistance : 8 kg/cm
- Dielectric strength : 40 Kvolt/mm
- Insulation strength : 1 x 106 Ohm/mm
- Impact resistance : 3.2 Joules
- Adhesion to steel (With primer) : 2.6 N/mm
- Adhesion to self : 0.5 N/mm
- Temperature range : -5~ C to 90~ C

2) Polyethylene outer wrapping coating tape
Thickness should be minimum 0.229 mm (0.009") with 0.102 mm (0.004") self-adhesive compound.
Polyethylene to be White or Silver-Grey light reflecting. Final thickness should be defined as per vendor
Characteristics of tape:
- Elongation : Min 200%
- Dielectric strength : Min. 10 KVolt
- Insulation resistance : 1x1012 Ohm/in

The Polyethylene wrapping coating tapeis extensively used in the pipework of oil and natural gas transportation, petrochemical industry,

electric power, metallurgy, urban natural gas network of pipes, the outside anticorrosion project of the
metal pipes involved as well as the outside anticorrosion project of the underground and overhead
metallic conduit of the works of petrochemical industry, natural gas and coal transportation.

Polyethylene wrapping coating tape-Feature:

Excellent adhesion to a wide range of industries, steel piping.
Effortlessly applied with no special equipment (mouldable by hand).
Compatible with common pipe coatings
Endures extremes of heat and cold.
Excellent resistance to cathodic disbondment.
High water and vapour impermeability.
Complies with ISO,DIN30672,AWWAC214 209,ASTMD1000.EN12068

Application of Polyethylene inner wrapping coating tape

The inner-layer tape shall be applied directly onto the prepared pipe surface using mechanical constant
tension coating equipment. The inner layer tape shall be spirally applied with overlap width and
application tension as recommended by manufacture. When applied to spirally welded pipe , the
direction of the tape spiral shall be generally parallel to the weld spiral. The minimum overlap shall
not be less than 25 mm. When a new row of tape is started, the ends shall be overlapped at least
150 mm measured circumferentially.

Application of Polyethylene outer wrapping coating tape

The Outer-layer tape shall be applied over the inner -layer tape using the same type of mechanical
equipment used to apply the inner-layer tape. The overlap of the outer-layer tape shall not coincide
with the overlap of the inner-layer tape. The minimum overlap of the applied tape and minimum end lap
of two rolls shall be the same as that of inner-layer tape. The outer-layer tape shall be applied at minimum
roll temperature of 21 ℃. The tape manufacture shall be consulted for recommended temperature of roll
above 21 ℃ to enhance conformability of the outer-wrap to the pipe surface.
