Weather-Resistant PE Outer Tape Cold Applied Tape for Oil & Gas Pipeline Corrosion Protection
System Description
The outer tape series is Cold applied tape coating system for corrosion protection of Oil, Gas, Petrochemical, and Waste Water underground or overhead pipelines. The outer-layer tape backing shall be compounded so that it will be resistance to outdoor weathering.
The outer-layer tape shall be applied after the inner-layer tape by hand or with a wrapping machine.
PE Outer Tape 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
