Repair Patch Rolls For 3PE Heat Shrink Sleeves Coating Damage
Repair patch For Pipe Corrosion Protection
Description:
Pipeline Repair patch is made of cross-linked polyolefin sheet coated with high performance heat melting adhesive. Coating Repair patch are used to add corrosion protection or fill voids in damaged coatings.
Repair Patch is designed for repair of damaged PE-coating on steel pipe and the amendment of the holes or crack which the diameter smaller than 100mm on the backing layer of Heat Shrinkable Tape/Sleeve. If damage area of coating pipeline greater than 100mm. Heat Shrinkable Wraparound Sleeve (or Heat Shrinkable Wraparound Tape) is recommended .
Features & Benefits
Closure patch consists of an irradiated, cross-linked polyolefin sheet coated with a heat activated adhesive.
Mainline coating repair products including melt stickers and repair patches compatible with common pipeline coatings.
Both the sticker and patch can be installed quickly with no special tools required.
The installed patch provides a barrier to moisture and corrosion and is resistant to abrasion and shear forces during pipeline installation and while in-service.
