Product Description
3PE Heat Shrinkable Wraparound tapes
Heat Shrinkable Wraparound tapes is superior performance heat shrinkable products designed for corrosion protection on field applied girth-weld joints of buried and exposed steel pipelines,The inner layer is two-components epoxy primer which coated on steel pipe; Intermediate level is special hot melt adhesive ;outer level is cross linked polyethylebe backing. 
Features & Benefits
●Heat shrinkable wrap tapes provide great corrosion protection, Superior resistance to Cathodic Disbandment and excellent durability against abrasion and chemical attack. The result is effective, good performance of sealing, wide application, easy to operate and preheating temperature,,long term protection against corrosion.
● with a separate closure
● Cross-linked backing provides superior abrasion, mechanical and chemical attack resistance.
● Excellent resistance to Cathodic Disbondment to ensure long-term corrosion protection
● Just-in-time customized lengths allow bulk rolls to be field cut top protect any pipe size
● Open sleeve configuration allows the product to be applied after the pipeline has been welded and cleaned.
