What is saddle fusion? Saddle fusion (sidewall fuson) is, like butt fusion and socket fusion, another process based on hot plate welding. Saddle heat fusion differs from either socket, or butt fusion methods by performing fusion into the side of the pipe wall in a transverse orientation to the main pipe, rather than in line with the pipe. Hdpe saddle welding required workshop saddle fusion machines. This hdpe fusing process can be conducted while pressurized creating a [hot tap" when allowed by regulations and the pipeline owner. The pipe and saddle fitting surfaces are heated/fusing until they reach a proper temperature, the heating tool is removed and then the weld is formed. The process is complete following a cooling process. Always have a trained joining operator perform this procedure using properly maintained Pipe Fabrication Workshop Machines.
