There are several noteworthy achievements in the technological innovation and research and development of HDPE pipe heat fusion butt welding machine. Firstly, the heat fusion butt welding connection method is one of the most commonly used connection methods for HDPE pipes at present. The quality of this type of connection is affected by a variety of factors, such as pipe wall thickness, pressure, temperature, time, ambient temperature and weather conditions.
Through the study of these key factors and engineering practice, a complete set of methods for controlling process parameters in the welding process of HDPE pipelines has been summarised, which greatly improves the quality of welded joints and construction efficiency.
In addition, some innovative and patented technologies have emerged. For example, Guangdong Power Grid Limited and Zhongshan Power Supply Bureau of Guangdong Power Grid Limited have invented a new device and method for heat fusion welding of HDPE pipes. This device includes parts such as base, pipe clamping mobile device, milling tool holder, heating plate, etc. It can reduce the problems of high waterproofing and water-stopping requirements at both ends of HDPE pipes during operation or high difficulty and low efficiency of steel wire threading construction due to water ingress into the pipes when the water level is high.
These achievements reflect the innovative ability of the enterprise in the technical research and development of heat fusion butt welding machine, which not only makes progress in technology, but also improves the efficiency and safety in practical application.
