water pipeline inner-layer tape
State-of-the-Art Pipeline Protection for All Climates & Environments
System description:
WATER PIPELINE Inner -layer tape also be called pipe wrap anti-corrosion tape, polyethylene wrap tape.
water pipeline Inner-layer 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-layer tapeT100 series is cold applied tape coating system for corrosion protection of Oil, Gas, Petrochemical, and Waste Waterburied pipeline, pipe can be buried, also can be underground ,overhead ,onshore and offshore .
Structure of water pipeline inner wrap tape
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-DIN 30672 and AWWAC-214 international standards and also ASTM standards.
Be used for water pipeline corrosion protection
