Pipe coating materials PP wrap tape

Pipe coating materials PP wrap tape the XUNDA-T 500 series is cold applied tape for both metallic pipelines and waterproofing works against outdoor bad weathers .

Pipe coating materials PP wrap tape shall be applied after the Liquid adhesive by hand or with a wrapping machine.

Pipe coating materials PP wrap tape is a bituminous self-adhesive joint sealing and water proofing membrane with an integral robust, woven polypropylene backing medium,which imparts high mechanical strength, impact resistance and elasticity;

xunda company for corrosion prevention and dielectric protection and is typicallyused for underground pipe work and metal structures, particularly

concrete sealing and bitumen overlaying on roads

Structures

The specification of the tape consists of three layers,

Adhesive layer: Butyl rubber Bituminous Compound

Backing : PP woven fabric cloth

Interleaf:Film Treated with Silicone

Pipelines protection

1:Weld joints 2:Bends 3:Fittings 4:Bare pipe lengths 5:Pipe rehab and repair 6:Bare pipe length

Pipes protection

Cold applied Excellent self adhesion to pipe Flexibility provides extra protection at vulnerable areas Excellent conformability and consistent uniform thickness Easily applied with no special equipment Compatible with common pipe coatings Excellent resistance to cathodicdisbonding

Usage

This successfully proven tape is the best solution for coating

of pipes and/ or repair, due to its tenacious adhesion,

mechanical characteristics, ease of use, good elongation and flexibility.

Xunda T500 Polypropylene bitumen tape exhibits exceptional

adhesion to concrete, metals and plastics. When adhering to

porous surface it may be beneficial to use Flexi Seal Primer.

The plastic nature of the product allows it to comfortably

accommodate both substrate vibration and some movement.

Production

Xunda T500 Polypropylene is produced in one of the

newest and most modern plants in the world.

The quality control department constantly and continuously

monitors the raw materials, the production and packaging

in order to ensure a high quality product. Sizes, article and

batch numbers are indicated on each roll.

Application

1 Rust Removal

Steel Surface needs treating. Its quality shall reach Sa2 or St3 grade as prescribed in GB8923-88 Pre-paint Steel Surface Rust Grade and Rust-removal Grade, and it shall be dust-free.

2 Priming

Primer shall be stirred well before painting. An even film of primer is painted on the steel surface that is rust-removed completely and dust-free. After the primer dries up (one may feel no sticky). The steel pipe can be wrapping with tape (it usually takes 3 to 5 minutes). The primer dosage usually amounts to 80 to 100g / m².

3 Inner Tape (Anti corrosion Tape) & Outer Tape (Protection Tape) Wrapping

The steel pipe that is painted with primer is wrapping with tape by means of suitable devices or tools as per joint needs, and wraps the inner tape and then wraps the outer tape. Tape tensibility can be 10 to 20 N / cm. The overlapped length between beginning and end of an adhesive tape shall be no less than 1/4 circumference of the steel pipe and the total length of adhesive tape shall be no less than 100mm. each film shall be paralleled, and must not be twisted and rumpled.
