What are the temperature requirements for electrofusion reducer during installation

During the installation of the electrofusion reducer, the control of the ambient temperature is crucial, and it is usually required to be maintained within the range of 5℃ to 45℃. This temperature limit is because the success of the electrofusion reducer depends on precise heat management. If the temperature is too low, the heat conduction efficiency during the electrofusion process will be significantly reduced, and the contact surface of the pipe and the pipe fittings may not reach the required melting temperature, resulting in insufficient connection strength and even the potential risk of water leakage or air leakage. Relatively speaking, too high a temperature will accelerate the melting of the pipe and the pipe fittings, which may lead to a decrease in the structural strength of the connection point, or even overheating and burning, thereby affecting the safety and stability of the connection. Therefore, in order to achieve the ideal electrofusion reducer effect, it is recommended to keep the ambient temperature between 20℃ and 25℃ to ensure that neither too cold nor too hot occurs.

In addition to the ambient temperature, the temperature of the pipe itself also has an important influence on the quality of the connection. In actual installation, the surface temperature of the pipe should not be lower than 5℃. If the surface temperature of the pipe is too low, the heat conduction capacity will be affected, the uniform transfer of heat during the welding process will be difficult to achieve, and the connection effect will be seriously weakened. In cold environments, the hardness of the pipe material increases, resulting in decreased processability, and cracks or incomplete connections are prone to occur during the welding process. To avoid such problems, installers usually need to preheat the pipe with the help of heating equipment to make its temperature close to the ambient temperature to ensure smooth welding of the connection surface.

In a high temperature environment, the plasticity of the pipe will be enhanced, which is conducive to the melting of the pipe during the electrofusion welding process. However, excessively high temperatures can also cause other problems, such as the expansion of the pipe, which in turn affects the connection state between the pipe and the electrofusion joint. When the temperature exceeds 45°C, the thermal expansion of the pipe may cause the pipe and the pipe fitting to fit loosely, thus affecting the quality of the electrofusion reducer. In this case, even if the electrofusion process is normal, the sealing of the welding point may be affected. Therefore, when installing in hot weather or high temperature environments, special attention must be paid to temperature control to prevent improper connection due to thermal expansion.

In view of the effect of temperature on the quality of the connection, the use of the electrofusion machine must also strictly follow the relevant standards. The electrofusion machine generates heat through electric current to heat the joint surface of the pipe and the electrofusion joint, so its operating temperature must be strictly controlled. During operation, the heating power and time of the electric fusion machine should be adjusted according to factors such as the material and specifications of the pipe and the ambient temperature. Usually, the temperature control system of the electric fusion machine will automatically adjust the current, time and temperature during the heating process, but the installer still needs to judge the suitability of the operating parameters according to the site environment and the specific conditions of the pipeline. If the site ambient temperature is low, it may be necessary to appropriately increase the heating power of the electric fusion machine; conversely, if the ambient temperature is high, it may be necessary to shorten the heating time to avoid damage caused by overheating.
