Product Description Polyethylene Heat Shrinkable Sleeve for Anticorrsion Coating of Oil and Gas PipelineProduct DescriptionHeat shrinkable sleeve/belt is suitable for steel pipe with 3-layer PE or 2-layer PE anti-corrosion system,fusion bonded epoxy,insulated pipe jacket and HDPE drainage pipeline. On the basic of the original product(heat shrinkable sleeve/belt with 2 layers) Qingdao Huashida Machinery Co., Ltd. has developed the 3-layer fiber reinforced PE heat shrinkable sleeve/belt is composed of cross-linked polyethylene back, a middle layer of fiber and special heat melt adhesive. The 3 layer reinforced sleeve/belt gives better shrink ratio, and better strength. It is resistant to corrosion, wear, impact, UV and aging, easier to be operated. Application scope:The heat shrinkable sleeve/belt is designed to be applied with minimum preheating and is ideal for large diameter wastewater pipe, steel pipe with 3-layer PE protection system and pre-insulated pipeline joint closure.- application of heat shrinkable sleeve 1) Oil & Gas Pipe2) For pre-insulated pipe3) For metal reinforced HDPE corrugated pipe (drainpipe)4) Plastic manhole - application of heat shrinkable belt Construction 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.Feature of our heat shrinkable sleeve/belt :1.Fast shrinkage speed,2.good waterproof performance,3 good anti-corrosive performance,4.long service life, convenient transportation and fast construction.5.using pure PE material and imported adhesive for ensuring the qualityProduct Parameters Technical parametersNO Text Item UnitPerformanceText ResultText MethodBack Material 1 Tensile Strength MPa ≥17 19.47 ASTM D638 2 Elongation % ≥400 626 ASTM D638 3 Vicat Softening Point oC ≥90 92 ASTM D1525 4 Brittleness Temperature oC <-65 <-65 ASTM D2671C 5 Dielectric Strength MV/m ≥25 33.13 ASTM D149 6 Volume Resistivity Ω.m ≥1*1013 1.1*1013 ASTM D257 7 Environment Stress Crack h ≥1000 >1000 GB/T1842 8Chemical resistance (7d) 10% HCI Tensile strength MPa ≥85 104.9 ASTM D638 Elongation % ≥85 96.3 ASTM D638 10% NaAH Tensile strength MPa ≥85 102.1 ASTM D638 Elongation % ≥85 95.6 ASTM D638 10% NaCL Tensile strength MPa ≥85 108.3 ASTM D638 Elongation % ≥85 94.1 ASTM D638 9 Thermal aging (150oC,168h) Tensile strength MPa ≥14 20.7 ASTM D638 Elongation % ≥300 630 ASTM D638 NO Text Item UnitPerformanceText ResultText MethodAdhesive 1 Lap ShearMPa ≥1.01.5ASTM D10022Softening Point oC ≥90 90.1ASTME283Brittleness Temperature oC <-15 <-15 ASTM D2671C 4Peel strength(23+/-2oC ) SteelN/cm≥70145.6ASTM D1000PrimerN/cm≥70205.9ASTM D1000PE layerN/cm≥70190.0ASTM D1000
