At a recent pipeline project in Superior, Wis., near Duluth, a large national pipeline distribution company used E.H. Wachs Split Frames portable pipe cutting and beveling machine tools to deliver the precise fit-ups the project required. The scope of the project included installation of a replacement section that was remotely fabricated, cold cut and weld prepped on site, lowered into its cradle and final welded. Although this particular project used torch cutting for the destructive cuts, when it came time to cut the sections for the critical fit-ups (nicknamed the "money cuts") the client insisted on the precision that only cold cutting can deliver. Cold cutting, or more precisely using portable machine tools to machine the cuts and bevels, can maintain critical tolerances under 1/32-in. (0.0313 in. or 0.794 mm) that are difficult or impossible to achieve using other methods.
