Product Description Oil Gas Pipeline Heat Shrinkable Tape for Field Joint Girth Weld Protecting Anticorrosion CoatingINSTRUSTIONPE backed heat shrinkable tape for pipeline is composed of two layers: radiation cross-linked polyethylene backing and special heat melt adhesive. The heat shrinkable sleeve is applied together with a solvent-free two-component epoxy primer to form a three-layer polyethylene anti-corrosion coating (3LPE) , which replicates the structure and performance of 3LPE coating in factory conditions, providing effective and long-term anti-corrosion for the welding joint of the steel pipe.During installation, the epoxy is applied to the prepared pipe surface and the heat-shrinkable sleeve is immediately wrapped around the joint over the wet epoxy. Heat is then applied to the sleeve which shrinks to form a tight fit around the joint. While curing, the epoxy forms strong mechanical and chemical bonds to the pipe surface and to the copolymer adhesive layer. The radiation cross-linked outer layer forms a tough barrier against mechanical damage and moisture transmission.Application:1. Field joint corrosion protection for gas oil steel pipeline.2.Field joint corrosion protection for water supply steel pipeline.3.3LPE coating repairing.Feature of our heat shrinkable sleeve:Brand new PE material and adhesive Strict quality controlFast shrinkage speedGood waterproof performanceGood anti-corrosive performanceLong service lifeEasy operationExecutive StandardProducts comply with national and international standards GB/T23257-2009, SY/T4054-2003, EN12068, DIN30672, GOST R51164-98 etc.TECHNICAL PARAMETERS NOTest 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 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.Text ItemUniPerformanceText ResultText MethodAdhesive1Softening PointoC≥9090.1ASTM E282Brittleness TemperatureoC<-15<-15ASTM D2671C3Lap ShearMPa≥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 informationA set of products includes heat shrinkable sleeve, closure patch and individually packaged epoxy primers.Max operating temperature: 60oCHSDS 60 is available:·pre-cut sleeve and separate closure patch·tubular sleeve·tape in roll (closure patch to be ordered separately)Specification of the pre-cut heat-shrinkable sleeve and seperate closure patch (or customized)Thickness: 1.5-3.5mmNo.Size, mmLength, mmPatchLength, mmWidth, mm1Ф159*500670500 802Ф219*5008601003Ф273*50010001004Ф325*50012001005Ф355*50013001006Ф406*50014601207Ф508*50018001208Ф610*50021701209Ф711*500250015010Ф813*500288015011Ф1016*500348015012Ф1219*500412020013Ф1420*5004780200Specification of heat shrinkable tape in roll (or customized)Width (mm)LengthThickness100The standard length is 5, 10, 15, 20, 30 meters per roll.PE layer 1.2mmHot melt adhesive layer, 0.8mm150200300450600HUASHIDA is a Heat Shrink Sleeve manufacturer with 20 years of production experience.The HUASHIDA Heat Shrink Sleeves have been exporting to many countries and win good reputation.HUASHIDA at international exhibitionsCertificatesHUASHIDA production park viewHUASHIDA team
