What is an Electrofusion 90° Elbow?

An Overview of Electrofusion Technology

Electrofusion is a joining process for thermoplastic pipes wherein heat, generated by the electrical current, is applied to effect this. This technology entails heating the pipe surface and the fitting’s surface using built-in heaters contained in electrofusion fittings. The polymer surfaces of the pipes and fittings are melted when current flows through the coils on their sides, forming a homogeneous bond as they cool down. By so doing, it ensures a secure joint and that it upholds integrity within the piping systems, thus minimizing the chances of leakage or failure. High-pressure environments and applications that need challenging yet flexible options, like water distribution systems, gas supply lines, and industrial piping, choose this more often than others due to its ease of installation and dependable performance, promoting long-lasting and efficient HDPE pipe systems.
