Comparison Between Butt Welding and Socket Welding for Plastic Pipes: Choose the Right Method for Peace of Mind

In the installation of UPVC, CPVC, PPH and PVDF plastic pipes, butt welding and socket welding are the mainstream connection methods. Butt welding requires no additional fittings; it involves heating and butting pipe ends, featuring high strength and good sealing performance. It is suitable for high-pressure and high-temperature working conditions with DN50 and above, such as PPH and PVDF chemical pipes, but has high requirements for equipment and operator skills. Socket welding is a socket connection, which is easy to operate and low in cost. It is suitable for normal temperature and pressure working conditions with DN50 and below, such as UPVC and CPVC pipes, but has the shortcomings of low strength and easy leakage. Jiangsu Hengda Plastic Pipe Industry reminds that it is necessary to select the type according to the pipe material and working conditions, and use high-quality pipes with standardized operation for longer service life.
