What is Pipe Fusion Welding - Bryan Hauger Consulting

Similarly, heat fusion joining for pipes and pipe fittings is a large urella term that contains specific procedures and methods such as electrofusion, butt fusion, socket fusion, saddle fusion, and so forth. There are many different methods for fusion welding plastic pipe and they all have their specific uses. Typically, two plastic parts (such as two polyethylene pipes) are welded or

What is electrofusion? - HDPE & PE pipe (polyethylene pipe)

Electrofusion is a simple method of joining PE pipes in circumstances where butt fusion is not practicable, such as where valves, elbows, and tees must be added. Prefabried fittings are used, incorporating an electrical heating coil which melts the plastic of both the fitting and the pipe, causing them to fuse together.
