Product Description

Heat Shrinkable Sleeve for District Thermal Heating Pipes

Product profile    
                                                    
HSS, Two-piece, with separate closures designed for the corrosion protection. HSWS 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).


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.

Features & Benefits:                                                

Heat Shrinkable Sleeves provide great corrosion protection, Superior resistance to Cathodic Disbondment and excellent durability against abrasion and chemical attack. The result is effective, good performance of sealing, wide application, easy to operate and preheating temperature low (50 celsius degree) ,long term protection against corrosion.

Easy installation
Saves time& money
Rapid & reliable Installation
Long term protection


HSS is a wraparound sleeve with a separate closure
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.
