Product Name: Oil Gas 3PE Pipeline Girth Welding Coating Heat Shrink Sleeve Model NO.: HSD Application: Gas/Oil/HDPE Pipeline Joint Character: Fast Shrinkable Rate, Water Proofing Thickness: 2.5mm.1.8mm.2.0mm3.0mm Trademark: HSD Transport Package: Standard Package Specification: EN253-2003,ISO1183-2004,ISO6964-1986,EN728-1997 Origin: Qingdao China HS Code: 39201090 Product Description Oil Gas 3PE Pipeline Girth Welding Coating Heat Shrink SleeveINTRODUCTIonPE heat shrinkable tape (sleeve) is composed of cross-linked polyethylene back and special heat melt adhesive. Heat melt adhesive has good bonding with PE back, steel pipe and Fusion bonded epoxy (FBE layer). By heating PE back shrinks, adhesive layer melts, and closely wraps around pipe joints, then it forms together with FBE afirm and continuous anti-corrosion body. It is resistant to corrosion, wear, impact, UV and aging,easier to be operated.Wrap around productsApplication area:It is mainly used for wrapping around pipe, anti-corrosion of kinds of pipe joints, and repairing pipes.For example: Oil and gas pipe, PU insulation pipe, 3PE/2PE steel pipe.TEST PROCEDURE AND TEST RESULT TEST PROCEDURE1. Clean the steel pipe and heat it by fire till over 80 ºC2. Paint the steel pipe with Primer (mixed with A&B)3. Fire heat the heat shrink sleeve, be attention to start heating from middle of the sleeve, but act from up and down, and gradually move from middle to two sides of sleeve, in order to drive air out of the sleeve, after finish heating, the good result is that there is about 1-2mm hot adhesive melt at the edge of sleeve.TEST RESULT1. Test result after cooling about 40 minutes. Peel strength to primer is over 100N per 2cm(till the end of the spring balance). at 30.7ºC Co-adhesive: Half-half.2. Test result after cooling about 24hours. Peel strength to primer is over 172N per 2cm at room temperature about 30.7ºC Co-adhesive: Half-half.Application:Radiation cross-linked Polyethylene (PE) Heat Shrinkable Sleeve is mainly used in anti-corrosion pipe, oil gas pipeline, fit for 3PE oil gas steel pipe also, 2PE steel pipe, thermal insulating pipe, epoxy powder coating, and PE drainage pipe etc. We have National Patent certifications for this product.AdvantageRadiation crosslinked PE heat shrinkable sleeve is made by basic material and melt adhesive. Our product has strong adhensive to make sure good quality of product; Easy operation, quick shrinking, low cost, perfect anti-water, anti-chemical corrosion, good insulativity and aging resistance. It is ideal material of anti-corrosion and thermal insulating system.EVA is imported. Brand Matsui Japan or Dupont USAThe heat shrinkable sleeve has been exported to Vietnam, Sudan, Kenya, Russia, Kazakhstan, Australia, Turkey etc.Specifications---3 Layer PE Coating Pipe---Offeshore &Underground---Oil, gas, water pipeline---DIA2''-72''---Pipeline size: From Ø108 to Ø1554 (4''---60'')Sleeves width: 100mm, 150mm, 200mm, 300mm, 450mm, 500mm, 600mm, 900mmClosure patch: 100mm, 150mm, 200mm (4'', 6'', 8'')Product StructureThe 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.Features &BenefitsHeat Shrinkable Sleeves provide great corrosion protection, superior resistance to cathodic disbandment 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 has been welded and cleaned.NOText ItemUnitPerformanceText ResultText 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/T18428Chemicalresistance(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 D638NO.Text ItemUnitPerformanceText ResultText MethodAdhesive1Softening PointºC≥9090.1ASTM E282Brittleness TemperatureºC<-15<-15ASTM D2671C3Lap ShearMPa≥1.01.5ASTM D10024Peel Strength(23±2ºC)SteelN/cm≥70145.6ASTM D1000PrimerN/cm≥70205.9ASTM D1000PE layerN/cm≥70190.0ASTM D1000Non-solvent Epoxy Primer5Shear of cured primerMPa≥5.012SY/T0041
