Product description of anti-corrosive heat shrink belt for pipeline:the anti-corrosive heat shrink belt for pipeline is designed for the anti-corrosion of welding joints of buried and overhead steel pipeline and the thermal insulation patch of thermal insulation pipeline.It is composed of radiation cross-linking polyolefin base material and special sealing hot melt adhesive, which can form good adhesion with polyolefin base material, steel tube surface and solid epoxy coating.during heating and installation, the base material is radially contracted while the inner composite rubber layer is melted and tightly wrapped at the filling mouth, forming a firm anti-corrosion body together with the base material outside the pipe, with excellent wear resistance, corrosion resistance, impact resistance and good anti-ultraviolet and light aging performance.Features of pipeline anti-corrosive heat shrink zone:-- high mechanical strength and strong aging resistance.Good resistance to environmental stress.-- excellent adhesion performance.-- easy to use.Executive standard:SY/T 0413-2002, NACE rp0303-2003The maximum operating temperature: 80 Suitable for exterior anti-corrosive coating:PE, FBE, PPSteel pipe preheating temperature: 75 Recommended derusting grade:Sa 2.5Product specification: the product can be used for dn100-dn1000 all steel pipesThe thickness of base material is from 1.0mm to 2.0mm, and the thickness of rubber layer is from 0.8-2.0mmHere is a Typical Value of the Property Test MethodBase materialThe Tensile Strength, Tensile Strength of GB/T1040-92 n/was 24Ultimate Elongation is 520% of GB/ t1040-92Dielectric strength GB/1408.1-99 33MV/ mVolume Resistivity Volume Resistivity GB/T1410-89 4.0 x10, mWater Absorption ASTM d570-2005Thermal aging (150, 21 days) GB/T1040-92Tensile strength 14.6n /mm2Elongation at break % 300%UV resistance to ageing EN12068Elongation at break % 480%Hot melt adhesiveSoftening point 123 GB/T4507Heat shrinkable sleevePeel strength GB/ t2792-98For primer steel N/cm 140N/cmThe PEN/cm 95 N/cmCathodic disbonding (60, 30 d, 1.5 v) 18 mm mm SY/T 0413-2002Hot water immersion astm d 870-2002 was not stratified and did not occur under test conditions There are signs of water erosion
