PE Inner Anti-corrosioin Tapes (T200)
|
|
|
|
| |
|
Coating System for pipelines-Outer Layer:
T200 series are 2-Ply polyethylene (PE) anticorrosive adhesive tapes. It is Cold wrap tape coating system for Corrosion Protection of Water, Oil and Gas Pipelines. The outer-layer tape backing shall be compounded so that it will be resistance to outdoor weathering.
Features:
Excellent adhesion to inner-layer tape and self
Resistant to UV
Can be applied over a wide temperature range
Good conformability and consistent uniform thickness
Easily applied with no special equipment
Compatible with common pipe coatings
Excellent resistance to cathodic disbonding
Meets ASTM D 1000 Standard
Cold applied
