Heat Shrinkable Sleeve

Heat Shrinkable Sleeve 1.1 ProductStructure 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.1.2 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 °C) ,long term protection against corrosion. 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 sizeOpen sleeve configuration allows the product to be applied after the pipeline hasbeen welded and cleaned.1.3 Specification( mm) Pipeline size: from Ø 108 to Ø 1554 (4''---60'') Sleeves width: 100mm, 150mm,200mm, 300mm,450mm,500mm,600mm Closure patch: 100mm, 150mm,200mm (4'', 6'', 8'') Model:HSS 3600/505/ Ø 1066.8 HSS--Heat shrinkable sleeves 3600------Roll length(mm) 505----- -Roll Width (as supplied) Ø 1066.8----Joint or pipeline Diameter 1.4 Technical Datas Width deviation (max) ±10% width or 0.25 in.(6mm), AWWAC216-5.3.1 Dielectric strength 400 V/mil(15 V/um) ASTM D149 Volume resistivity 1014 ohm-cm ASTM D257 Adhesion to steel 15 lb/in.width (25 N/cm) ASTM D1000 Lap shear 12 psi ASTM D1002 Heat shock No visual cracking,flowing, or dripping AWWAC216-5.3.8 Tensile strength 2200 psi min ASTM D638 Elongation 23 400% min ASTM D638 Impact resistance 25 in.-lb(282cm-N) ASTM G14 Impact Resistance ASTM G14 ≥50 Cathodic Disbondment at 23°C 30 days mm rad ASTM G 8 ≤25 Dielectric Breakdown Voltage 23°C MV/M ASTM D 149 ≥15
