PE Electro Fusion Joint for Pre-insulated pipeline

Polyethylene Electro Heating Fusion Tape / Sleeve/ hot meltTape Itis a kind of special-purpose pipe connection, which is made by embedding specific electric heating melt welding wire in the basis of high quality PE sheet with special technicals. Mainly used for Oil&thermal pipeline, such as Pre-insulated Pipes. Performance characteristic: good bonding strength, excellent seal, high air-tightness, no PU leak, corrosion resistant, aging resistant, and easy to operate. Electric hot melt sleeve is an emerging connect fitting in anti-corrosion and thermal insulating industries. Its largely outperforms heat-shrinkable strip in terms of aging-resistance, bonding strength, and ring stiffness, further more, it applies PU foam after melting the jacketed pipes, this process needs much less time than using a heat-shrinkable strip; therefore, electric hot melting sleeves are widely welcomed in joint coating and connecting of heat distribution pipeline and oil pipeline. Features & Benefits: Waterproof; good sealing capacity;Able to withstand axial forces initiated by axial moments of the pipe in the ground;Able to withstand radial forces and bending forces; high tensil strength;Able to withstand effects of temperature and temperature variatations.Have the same thickness of the pipeline insulation layer.Could be used as drawing pipe scope of application: DN200 DN3000mmTesting programRequired technicalTesting resultTesting methodAppearanceThe appearance of HDPE electric fusion sleeve is smooth and flat, no bubble, no split, no discolor because of decomposition; and the embessed fusion net is no disconnect and tilting.passTested by eye under the sunlight.Tensile strength≥13Mpa15.0MpaGB/T 8804.3-2003Hydraulic pressure test20°C,0.1Mpa water pressure, no damage and leakage after 1 hourpassGB/T 6111-2003Air leakage test20°C,0.1Mpa air pressure,no damage and leakage after 1 hourPassGB/T 6111-2003
