ISO9001 Origin: Qingdao, China HS Code: 39173900 Product Description Pipeline Joint Closure Sleeve HDPE Electro Fusion Wrap SleeveIt is a kind of connecting pipe fitting what is widely used on anti-corrosion, especially on Directly buried pre-insulated pipes field joint. It is made by Polyethylene sheets complex with the electro-fusion wireApplication:1. District thermal heating system construction,2. Pre-insulated pipes field joint welding and oil pipes joint welding;3. Preinsulated bonded pipe system for directly buried hot water networks;4. Three PE/PP layers with foam jacket insulation pipes connection;5. Steel pipes anti-corrosion etc.Performance:1. Waterproof; High adhesion, good airtightness, corrosion resistant capacity, long service life and convenient operation2. Able to withstand axial forces initiated by axial movements of the pipe in the ground;3. Able to withstand radial forces and bending moments;4. Able to withstand effects of temperature and temperature variations.5. Have the same thickness of the line pipe insulation layer.SpecificationSteel pipe outside diameter (mm)PE outside casing diameter (mm)Width(mm)Tic.mmDN1592856004DN2193156004DN2733656004DN3254206005DN3775006005DN4265506006DN4786306006DN5296556006DN6307606008DN7208506008DN82096060010DN920105460010DN1020115560012DN1220138060012Technical data:All of test according with the EN253-2003,ISO1183-2004,ISO6964-1986,EN728-1997Final TestUnitStandardTest ResultResultRaw material densityg/cm 3≥0.935≤0.961PASSRaw material melt flow rateg/10min≤0.500.46PASSAppearance check/Inernal and external surfaces is clean and free from other defects.PassPASSHeat reversion%≤3;shall not show any cracks0.89,No cracksPASSTensile yield strengthMpa≥1920.2PASSElongation at break%≥350656PASSStress crack resistanceh≥300PassPASS
