How to solve the uneven connection during the connection process of PE Butt Fusion Fittings

PE Butt Fusion technology is an efficient and reliable way to connect pipes, which is widely used in the transportation of water, natural gas and chemicals. The core of this technology lies in the uniformity of the connection, because it is directly related to the strength of the joint and the overall safety and reliability of the pipeline system. Uneven connections may not only lead to insufficient joint strength, but also cause safety hazards such as leakage, so it is crucial to ensure the quality of the connection.
During the hot melt connection process, it is crucial to ensure the flatness and cleanliness of the end face of the pipe fitting. Uneven end face or contaminants are common causes of uneven connection. If there is dirt, grease or other impurities on the end face of the pipe fitting, it will directly affect the quality of the fusion and thus affect the performance of the overall system.
In order to ensure the cleanliness and flatness of the end face, first use appropriate cleaning agents and tools to thoroughly clean the end face of the pipe fitting to ensure that no contaminants remain. After cleaning, use a special milling cutter to mill the end face of the pipe fitting to ensure its flatness and smoothness. After milling, use a clean cloth to clean the end face again to avoid the influence of impurities on the quality of the connection.
Temperature control is another key factor affecting the connection effect. Improper control of the heating temperature may cause uneven heating of the connection surface, thus affecting the welding effect. For this reason, it is recommended to use high-precision temperature control equipment to ensure that the temperature of the heater is set within the range recommended by the manufacturer. In addition, the equipment should be calibrated regularly to ensure the accuracy of its temperature control. During the heating process, the temperature of the heating surface is monitored regularly, and real-time monitoring is carried out using equipment such as infrared thermometers to ensure the uniformity of heating.
During the connection process, reasonable pressurization time is as important as pressure setting. Improper pressure and time applied may lead to uneven connection. A dedicated press should be used to ensure that the pressure applied during the connection process is uniform and appropriate to avoid deformation of the joint caused by uneven pressure. At the same time, according to the specifications and material properties of the pipe fittings, the pressurization time should be reasonably set to ensure that the connection surface is fully contacted and melted to form a firm joint.
