Factors affecting the quality of PE electrofusion pipe fittings: First, the influence of voltage and current fluctuations on the quality of the interface. For the quality qualified electrofusion pipe fittings, the resistance value of the internal pre-resistance wire is constant; it cannot be directly connected to a high-power machine. The power supply for welding shares a single cable; generally, the input cable of 2.5mm2 is used when the welding machine is within 50 meters from the power supply. When the welding machine is 50-100 meters away from the power supply, a 4mm2 input cable should be selected. When the welding machine is 100 meters away from the power supply, the input cable should be thickened or a generator should be connected. The quality impact of electrofusion pipe fittings is generally based on the factory standard of electrofusion pipe fittings, and the welding time parameters are generally designed according to the ambient temperature of 20°C. If the ambient temperature is different during the welding process, it means that the heat conduction conditions of the pipe fittings change during the welding process, which directly affects the welding quality. Finally, the impact of improper operation on the quality of the interface, the pipe connection port is not scraped or processed properly, the pipe port is not chamfered or has debris; the positioning is incorrect, the pipe is inserted deep enough - not enough, the pipe and the pipe fittings are not on the same axis There is external stress; the coil pipe is not straightened before welding, or the pipe with large bending deformation has not been rounded.
