McElroy’s No.412 line of fusion machines fuses pipes at the ends of sizes from 4″ IPS to 12″ DIPS (110mm to 340mm). They come in various model configurations, to meet the demands of your pipeline project. Rolling412 changed the industry when it was introduced as the world’s first fully self-contained fusion machine

All units incorporate the interchangeable four-jaw trolley No.412, which can be easily removed for melting in the trench. In the case of very narrow installations, the external fixed jaw and skid can be removed from the trolley, turning it into a 3-jaw carriage to have an even more compact melting unit. These machines can manufacture segmented elbows with optional mitered inserts and are compatible with DataLogger®.
