Pipe Connection
★ Key Pipeline Connection Techniques:
1. For dn≤63: Opt for hot melt socket or electrofusion connections for optimal results.
2. For dn≥75: Hot melt butt or electrofusion connections are recommended for enhanced security.
3. For connecting with metal pipes or accessories: Utilize flange or transition pipe connections for seamless integration.
★ Electrofusion Connection Process
1. Prepare by thoroughly cleaning the pipe surface and marking the insertion depth for accuracy.
2. Scrape the surface layer to ensure perfect adhesion.
3. Align and sleeve the electrofusion fittings onto the pipe, ensuring straightness and axial alignment.
4. Perform the weld; a slight melt should be visible from the observation hole, indicating successful fusion.
5. Allow to cool, completing the electrofusion process with precision and care.
