Pipeline wrap tape System description:
Inner wrap tape also be called pipe wrap anti-corrosion tape, polyethylene wrap tape.
Inner wrap tapeT100 is engineered to assure a high bond to the primed pipe surface with excellent conformability characteristics, aggressive adhesive for corrosion protection and repair of main line coatings.
Inner wrap tapeT100 series is Cold applied tape coating system for corrosion protection of Oil, Gas, Petrochemical, and Waste Water pipelines, pipe can be buried, underground ,overhead ,onshore and offshore .
Structure:
The specification of the tape consists of two layers, adhesive layer and film backing.
Adhesive: Butyl rubber
Film backing: Special blend of stabilized polyethylene
Features & Benefits:
Provides a permanent bond to the primed steel pipes surface and provides protection against chemical electrolytic corrosion for underground pipelines.
long term corrosion protection
Worldwide reference lists. Established in-ground history
High chemical resistance under service temperature.
Outstanding electric property and permanent adhesion.
Cold applied, No release liner. Makes installation fast and easy.
Complies with EN-DIN30672 and AWWAC-214 international standards and also ASTM standards.
Method Of 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.
