SIFFO HDPE (High-Density Polyethylene) electrofusion fittings are specially designed for joining HDPE pipes using electrofusion welding technology. These fittings have built-in heating wires that melt the pipe and fitting surfaces when an electric current is applied, creating a strong, leak-proof joint. They are widely used in gas, water supply, industrial pipelines, and mining applications due to their durability and corrosion resistance.
Key Features
·Strong & Leak-proof – Ensures a homogeneous fusion for a permanent joint.
·Corrosion Resistant – Suitable for aggressive environments.
·Easy Installation – Requires minimal equipment and labor.
·Long Service Life – Resistant to chemicals and UV radiation.
·High Pressure Resistance – Suitable for high-pressure fluid transport.
