Polyken 955 mechanical protection outer wrap tape for steel pipeline
System description:
Outer wrap tape also be called outer layer protection tape, pipe wrap tape, polyethylene adhesive tape.
Outer wrap tape T200 is engineered to achieve a complete bond to the inner layer tape, providing maximum handling and in-service protection for the coating system.
Outer wrap tape T200 series is Cold applied tape coating system for corrosion protection of Oil, Gas, Petrochemical, and Waste Water pipeline. 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
Excellent adhesion to inner-layer tape and self
long term corrosion protection , Resistant to UV
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.
