Excellent adhesion to pipe and self. Can be applied over a wide temperature range . Good conformability and consistence
Coating System for pipelines-Inner Layer
Maiqiang 980 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 inner-layer tape shall be applied after the Primer and before the Outer-layer tape.
Coating System for pipelines-Outer Layer
Maiqiang 955 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.
