3-Ply PE Pipe Coating Tape / Underground Pipeline Inner Tapes for Corrosion Protection
1. 3-ply PE anti-corrosion inner tape system description:
The 3-ply PE anti-corrosion inner tape 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 stabilized 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 3-Ply PE anti-corrosion inner tape shall be applied after the Liquid adhesive and before the outer-layer tape by hand or with a wrapping machine
2. 3-ply PE anti-corrosion inner 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
3. 3-ply PE anti-corrosion inner tape 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
