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
