Product Description Two-layer Heat Shrink Tape for Oil Gas Pipeline Girth Welding Corrosion Protective Coating Ce CertificateProduct Description INSTRUSTIONPE 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.Detailed Photos 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 operationProduct Parameters Executive 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.Our Advantages The HUASHIDA Heat Shrink Sleeves have been exporting to many countries and win good reputation.Packaging & Shipping HUASHIDA at international exhibitionsCertificatesCertifications HUASHIDA production park viewHUASHIDA team
