Pipe Connection
★ Main Pipeline Connection Methods:
1. For dn≤63, utilize hot melt socket or electrofusion connections for secure joining.
2. For dn≥75, hot melt butt or electrofusion connections are recommended for optimal integrity.
3. Connect with metal pipes and accessories using flange or transition pipe methods.
★ Electrofusion Connection:
1. Clean and mark the insertion depth on the pipe to be joined for precision.
2. Scrape the outer layer to ensure a clean and secure connection.
3. Align and sleeve the electrofusion fittings onto the pipe, maintaining straightness and alignment.
4. Perform electric welding, ensuring a slight melt is visible for quality assurance.
5. Allow for cooling to complete the electrofusion process, ensuring a robust connection.
