Heat-shrinkable Products

 

Product type

Heat shrinkable technology coatings.

Coating technologies based on heat shrink force, able to provide long-term protection against corrosion combined with high mechanical resistance performance. Heat shrinkable products consist of a irradiated cross-linked polyolefin backing, combined with a hot melt or pressure sensitive adhesive. Furthermore, they are compatible with all factory applied mainline coatings.

Features and benefits:

    • Available in various thicknesses and adaptable to any pipe diameter.
    • Excellent resistance to cathodic disbondment, hot water immersion, thermal aging and soil stress.
    • Two-layer and three-layer wraparound sleeves (with and without primer) also available in “Uni-sleeve” construction (with pre-attached closure patch).
    • Direct installation on steel for two-layer sleeves (primer-less).
    • Backing provided with thermal “permanent change” indicator (Dimpled pattern) that disappears with proper heat application during shrinkage. The evidence of permanent change guarantees an immediate and long-term verification of the correct installation.
    • Combination of excellent performance, competitive costs and ease of installation.

Heat shrinkable products meet all relevant international standards (ISO, EN, etc.) and comply with SNAM‘s GASD  specifications.
