Product Description Pipeline 3lpe Steel Gas Oil Water Supply Pipe Field Joint Coating Heat Shrinkable Sleeve INTRODUCTION PE heat shrinkable sleeve has a two-layer structure, it is composed of radiation cross-linked polyethylene backing and special heat melt adhesive. The shrink sleeve should be applied together with non-solvent two component epoxy primer for field joint coating for steel pipeline.Heat melt adhesive has good bonding with PE backing, steel pipe and epoxy primer. By heating PE back shrinks, adhesive layer melts, the sleeve closely wraps around the pipe joints. It forms together with the epoxy primer a firm and continuous anti-corrosion body, which is similar to the 3-layer anticorrosive coating in factory conditions. It is resistant to corrosion, wear, impact, UV and aging, easier to be operated. Application area:It is mainly used for field joint coating, wrapping around pipes, anti-corrosion of kinds of pipe joints, and repairing pipes. For example Oil and gas pipe, PU insulation pipe, 3LPE/2LPE steel pipe.Field joint coating of steel pipe with 3LPE coatingFeature of heat shrinkable sleeve HSD:1.fast shrinkage speed,2.good waterproof performance,3 good anti-corrosive performance,4.long service life5.using pure PE material and imported adhesive for ensuring the quality TECHNICAL PARAMETERSNOTest ItemUnitPerformanceTest ResultTest MethodBack Material1Tensile StrengthMPa≥1719.47ASTM D6382Elongation%≥400626ASTM D6383Vicat Softening PointoC≥9092ASTM D15254Brittleness TemperatureoC<-65<-65ASTM D2671C5Dielectric StrengthMV/m≥2533.13ASTM D1496Volume ResistivityΩ.m≥1*10131.1*1013ASTM D2577Environment Stress Crackh≥1000>1000GB/T1842 8 Chemicalresistance(7d)10%HCITensile strengthMPa≥85104.9ASTM D638Elongation %≥8596.3ASTM D63810%NaahTensile strengthMPa≥85102.1ASTM D638Elongation%≥8595.6ASTM D63810%NaClTensile strengthMPa≥85108.3ASTM D638Elongation%≥8594.1ASTM D6389Thermal aging(150oC,168h)Tensile strengthMPa≥1420.7ASTM D638Elongation%≥300630ASTM D638 NO.Test ItemUniPerformanceTest ResulTest MethodAdhesive1Softening PointoC≥9090.1ASTM E282Brittleness TemperaturoC<-15<-15ASTM D2671C3Lap SheaMPa≥1.01.5ASTM D1002 4Peel Strength(23±2oCSteelN/cm≥70145.6ASTM D1000PrimerN/cm≥70205.9ASTM D1000PE layerN/cm≥70190.0ASTM D1000Non-solvent Epoxy Primer5Shear of cured primerMPa≥5.012SY/T0041Ordering informationHeat shrink sleeve is available:·pre-cut sleeve and separate closure patch·pre-cut sleeve with pre-attached closure patch·tape in roll (closure patch to be ordered separately)Heat shrink sleeve workshopHeat shrink sleeve equipmentThe heat shrink sleeve equipment is designed and manufactured independently by our company and we also sell the equipment.Please click the link for more information.
