Polyethylene pipe electric fusion welding process 
 Buried polyethylene pipe electric fusion welding process hot melt polyethylene pipe principle, through the electric heating method, the connector casing and pipe jacket melting, welding high strength, used in the form of a variety of laying insulation tube joint construction, the number of engineering Practice has proved that this construction process is convenient, reliable quality. 
 Specification 
 Buried insulation of the current production of the DN200 specifications prefabricated pipe are supporting electric hot melt section. 
 Configuration 
 Special electric welding sets section 
 A dedicated electronic control box 
 Clamping device 
 Technical Features 
 1 unique welding process, to ensure that the connector casing, pipe welding materials unified. 
 (2) does not exist in the hot fusion welding stress, and higher than the thickness of the jacket pipe weld thickness, so the tensile strength higher than the parent metal. 
 Dedicated electrical control box connector of different diameters heating process to achieve full automatic control of the procedures to get the best melt temperature control of process parameters of different diameters, compare Austrian and reliable welding quality. 
 4 to call for the construction of the energy, process adaptability, ease of field construction. 
 (5) does not involve other auxiliary, the main materials are prefabricated so convenient. 
 Uses: mainly used in anti-corrosion insulation pipes, heat pipe interface connection. 
 Features: good sealing performance, corrosion resistance, long life, easy to use
