Connection Method

1. Electrofusion Welding: This advanced technique utilizes specialized equipment to seamlessly meld the pipe ends and fittings. By heating and melting the materials, they fuse together to form a perfect bond, ensuring exceptional durability and reliability.

2. Butt Fusion Welding: This method offers a similar approach to electrofusion welding. By heating the pipe ends and pressing them together, a seamless and robust joint is created that maintains the integrity and strength of the piping system.

3. Flange Connections: Employing flange connections involves attaching flanges to the pipe ends. These flanges are then bolted together with gaskets, creating a highly secure and dependable seal, ideal for high-pressure applications.

4. Mechanical Couplings: This quick and efficient method uses compression fittings or clamps to join pipe sections. Mechanical couplings provide a rapid and straightforward connection solution, reducing installation time and effort.

5. Threaded Connections: Some of our steel wire reinforced PE composite pipes come with threaded ends. These allow for easy and secure connections with compatible fittings or adapters, offering versatility and ease of assembly.
