Pipe Wrap Tape System describe
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
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 polyethylene fines
Interleaf:Anti adhesive Film Treated with Silicone
3 Features:
Excellent bonding between adhesive and carrier film via co-extruded intermediate layer.
Mechanically highly resistant tape system.
Practically impermeable to water vapour and oxygen.
Resistant to soil bacterial and soil electrolyte.
Compatible with coating from PE,PP,FBE,PU,CTE and Bitumen and ext- .
A Total Coating System with:
High adhesion and shear resistance
Resistance to corrosion disbondment
High electrical resistance
High dielectric strength
High corrosion protection for steel substrates
