3PE Heat Shrinkable Sleeve With Closure Patch
1.10 years' expereances
2. Good anticorrosion
3. Good anti-leakage
4. Girth weld of 3PE pipelines
Product introduction
Heat Shrinkable Sleeve
Two-piece, with separate closures designed for the corrosion protection.
Heat Shrinkable Sleeve is superior performance heat shrinkable products designed for corrosion protection on field applied girth-weld joints of buried and exposed steel pipelines operating up to 80° C (176° F).
Instruction
The inner layer is two-components epoxy primer which coated on steel pipe; Intermediate level is special hot melt adhesive;
Outer layer is modified radiation crossing linking polyethylene backing
Advantages
Cross-linked backing provides superior abrasion, mechanical and chemical attack resistance.
High performance adhesive provides excellent resistance to Cathodic
Disbondment to ensure long-term corrosion protection
Just-in-time customized lengths allow bulk rolls to be field cut to protect any pipe size
Open sleeve configuration allows the product to be applied after the pipeline has been welded and cleaned.
