Pipeline 3 Ply Inner 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 stabilised polyethylene bcking 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 Pipeline 3 Ply Inner Wrap Tape shall be applied after the Liquid adhesive and before the outer-layer tape by hand or with a wrapping machine

 

Pipeline 3 Ply Inner Wrap Tape Structure

The specification of the tape consists of four layers,

Internal Adhesive layer:Butyl rubber

External Adhesive layer: Butyl rubber

Film backing:Special blend of stabilized polyolefines

Interleaf:Antiadhesive Film Treated with Silicone
