China Heat Shinkable Wraparound Sleeve for Oil Pipeline

Heat Shrinkable Wraparound Sleeve used for different drainage and sewer pipes, such as double wall HDPE pipe, steel enhanced corrugated pipe, provide great corrosion protection, Superior resistance to Cathodic Disbondment and excellent durability against abrasion and chemical attack. The result of heat shrink is effective, good performance of sealing, wide application, the sleeve easy to operate and preheating temperature low, long term protection against corrosion.
1. Heat shrink sleeve is a tubular sleeve.
2. Cross-linked backing provides superior abrasion, mechanical and chemical attack resistance.
3. High performance adhesive provides excellent resistance to Cathodic Disbondment to ensure long-term corrosion protection.
4. Just-in-time customized lengths allow bulk rolls to be field cut to protect any pipe size
5. Open sleeve configuration allows the product to be applied after the pipeline has been welded and cleaned.
