napipelines.com OCTOBER 2 018 | North American Oil & Gas Pipelines 31 To better explain, Wingo discussed a recent job involving two lines, one with six miles of 24-in. 375 wall pipe and the other with seven miles of 30-in. 406 wall pipe. Wingo used two plasma torches mounted on a Mathey Dearman pipe cutter to bevel 57 pups in just over six hours. While one torch beveled, the other back beveled. He insists the number of cuts would have easily taken three times as long using oxyacetylene. The work was made even easier by Wingo's selection of two Freedom 38 PPA units from Hypertherm. The units are self-contained, combining a 38-kilowatt generator and air compressor, and include a 125-amp Power- max125 plasma cutting system. The unit is small enough to fit on the back of a welding rig, trailer or a crawler carrier. This makes it easy for pipeline crews to move the unit quickly and efficiently. ma for Pipeline Repair and Rehab
