Pipe wrap tape System description

The XUNDA-T400 series is Cold applied tape coating system for corrosion protection of Oil, Gas, Petrochemical, and Waste Water underground or overhead pipelines.

It is a three-ply cold applied tape with stabiliesed polyethylene backing and butyl rubber adhesive layers on both sides.It is also used as inner-layer tape. It shall be applied by hand or with a wrapping machine

The 3Ply tape shall be applied after the Liquid adhesive and before the outer-layer tape by hand or with a wrapping machine

2 Structure
