What is the hot melt temperature of PE water supply pipe?
The hot melt temperature for joining PE (Polyethylene) water supply pipes through fusion welding depends on the specific type of polyethylene used and the fusion method being employed.
For HDPE (High-Density Polyethylene) pipes, which are commonly used in water supply systems, the typical fusion temperature range is approximately 200 to 240 degrees Celsius (392 to 464 degrees Fahrenheit). This range is suitable for most fusion methods used in joining HDPE pipes, including butt fusion and electrofusion.
Here are some details about the fusion methods and their associated hot melt temperatures:
- Butt Fusion: In butt fusion, the ends of two HDPE pipes are heated until they reach the fusion temperature, and then they are pressed together. The standard fusion temperature for butt fusion of HDPE pipes falls within the range mentioned above, typically around 220 to 230 degrees Celsius (428 to 446 degrees Fahrenheit).
- Electrofusion: Electrofusion involves using specialized fittings with built-in heating elements. The fittings are attached to the HDPE pipes, and an electric current is passed through them, heating the pipe ends and the fitting until they reach the fusion temperature. The fusion temperature for electrofusion is generally within the same temperature range as butt fusion, typically around 220 to 230 degrees Celsius (428 to 446 degrees Fahrenheit).
Please note that the specific fusion temperature can vary depending on the manufacturer’s recommendations, the pipe size, and the local regulations or standards applicable to your region. It’s crucial to follow the manufacturer’s guidelines and local regulations when conducting fusion welding for PE water supply pipes to ensure strong, leak-free joints and the overall integrity of the water supply system. Additionally, proper equipment and training are essential to perform fusion welding safely and effectively.
